In addition to the Cosmosphere, a world-class space science museum, the city of Hutchinson, Kansas, features another prominent attraction: the only salt mine in the country that’s open to the public. Have I got your attention yet? Read on!
Formerly known as the Kansas Underground Salt Museum, Strataca is owned by the Hutchinson Salt Company, which began operations in 1923 as the Carey Salt Company. Nancy and I visited Strataca in late May 2022.
The salt extracted from the mine is not the type that you’ll find in your kitchen salt shaker. There are a number of impurities in the mineral, which makes it ideal for managing icy roads and for feeding livestock.
Strataca’s story begins, as do all of the good ones, in the late part of the Paleozoic Era, known as the Permian Period, about 275 million years ago. Kansas, along with much of the rest of present-day North America, was covered by a vast inland sea. The waters eventually receded, leaving behind an immense deposit of salt that, over tens of millions of years, was covered with layers of shale and other sediments like sand, gypsum, and silt. That 275-million-year-old deposit of salt is now 650 feet below the Kansas prairie.
The museum has been at this location on the east side of Hutchinson since 1986. Of the 15 salt mines in the United States, Strataca (née the Kansas Underground Salt Museum; the name was changed in 2013) is the only one that is open for visitor tours. I’m trying to remember to take pictures of the exteriors of the museums we see; it seems that the American flags are flying at half-mast more often than not. We visited Strataca on Memorial Day.
A double-deck elevator takes two sets of up to 15 people each on a four-minute trip 650 feet down into the bowels of the earth. (It’s not really the bowels of the earth; the top crust of the earth, which makes up about 1% of the radius of our planet, has an average thickness of nine to 12 miles. In other words, the 650-foot elevator ride takes visitors down about 1% of 1% of the earth’s radius. Still, the elevator ride is pretty neat!)
Excavating the shaft for this visitor elevator was no mean feat. In addition to penetrating hundreds of feet of sedimentary rocks, the shaft also had to descend through part of the Ogallala Aquifer – one of the world’s largest natural underground reservoirs. The aquifer is about 130 feet thick at the site of the museum. To construct the shaft, engineers used liquid nitrogen to freeze the area of the aquifer immediately surrounding the planned shaft, then excavated the ice and replaced it with a concrete liner. The process was completed in 15-foot increments, and took just over a year between March 2004 and March 2005.
Upon exiting the elevator, visitors enter a large chamber filled with interesting exhibits that tell the wondrous story of sodium chloride (NaCl). As you can see, every visitor has to wear a hard hat. I jostled my way to get a blue one. The temperature in the mine year-round is 68 degrees Fahrenheit, with a relative humidity of 45%.
Let’s go back topside for a moment. This map, located in the museum’s visitor center, shows the extent of the mine (in yellow) with the rest of the city of Hutchinson to the west (left). The 1.5-square-mile mine is immense; if each of the excavated areas was lined up in a straight line, the chamber would extend for 150 miles. Pillars of solid rock salt, 40 feet square, are left to separate each chamber and support the upper level of salt.
Okay, back down into the bowels of the earth 650 feet below the surface. Here’s a closeup of the salt deposit. As you can see, it’s quite different from the Morton’s that’s in your kitchen cabinet. The sodium chloride is mixed with a number of other minerals, including shale and sulfur compounds, which is why it’s primarily used to de-ice roadways.
The year 2023 will mark a century of mining by the Hutchinson Salt Company (formerly Carey Salt). It mines in the room and pillar process. This involves excavating, with the use of explosives, large chambers alternating with square pillars, measuring 40 square feet, that support the upper level of the mine. The process results in something of a checkerboard pattern, if it could be viewed from above. The mine’s chambers are very large, ranging from 2,500 to 15,000 square feet in size, with ceiling heights of 11 to 17 feet. The room and pillar method differs from traditional precious metal mining, in which miners follow the vein of gold or silver ore, for instance (unless it’s more cost-efficient to simply take an entire mountain apart, which seems to be happening more often).
Strataca has retained a lot of Carey Salt’s equipment from the early days of the mine (I’m guessing partly because it would cost time and money to return them to the surface, but it’s still fun to see the specialized equipment). The machinery is fairly well-preserved, considering the relatively high humidity; the salt can’t be good for metal parts, though. This machine was used to cut long slits at the bottom of a salt wall; when explosives in the wall were detonated, the slit ensured that the salt fragments fell forward into the chamber.
The excavation takes place in much the same way today, but using modernized equipment. The rock salt fragments are transported via conveyors to crushers, then taken to the surface using large buckets on a hoist. When operating at capacity, the skip, or mine elevator, can carry four tons of salt to the surface every three minutes. The skip is also used to transport miners into and out of the operation. Miners formerly used a rail system to move about the operation underground, but have since started using old junk cars that have been modified to run on bio-diesel fuel. Developed almost entirely from old cooking oil, the burning of bio-diesel doesn’t leave particles suspended in the environment. There are many instances of several generations of Hutchinson families being employed by the mine.
This was an interesting exhibit; it’s essentially a waste dump site. Early in the mine’s history, employees would leave their empty food packaging underground because it was more cost-effective to use the skip to transport either rock salt or miners. The salty environment, well away from the sun’s ultraviolet rays, has preserved the trash remarkably well; a lot of the sandwich wrappers and empty drink cups look like they were tossed aside last week instead of in the 1950s.
Nancy and I went on a couple of different guided tram rides through the mine. We got to see chambers that were excavated decades ago, using earlier mining methods. The mining company has placed a number of environmental sensors throughout the operation, which provide early detection of any possible shifting of the rock salt walls. The Mine Safety and Health Administration, which oversees operations in U.S. mines, considers this salt mine one of the safest in the world.
Nancy really enjoys being underground. I mean, really. She’d been looking forward to visiting the Hutchinson salt mine for a number of years, and we both had a great time. Luckily for us, our underground adventures were only beginning – we’d be able to descend into the bowels of the earth natural caves at two U.S. national parks in the months to come. Multiple times at each cave, even!
A salt mine might seem like something of a “so what?” kind of experience. But it’s the salt that comes from this mine, and others like it, that keep our roads safe to drive in wet and freezing weather. We’re glad we went, and, combined with the Cosmosphere, Strataca makes an excellent reason to visit Hutchinson.
Hutchinson, Kansas, seems to be an unlikely place for a world-class museum devoted to space exploration. The state’s main economic driver, by far, is agriculture: Kansas ranks in the top 10 states in the country for revenue from beef cattle, corn, hay, hogs, soybeans, sunflowers, and wheat (40 percent of all the winter wheat grown in the United States comes from Kansas).
However, the Sunflower State’s motto is “ad astra per aspera,” which, as you’ll recall from your Latin learnin’, means “To the stars through difficulties.” The motto is more a recognition that the state succeeded despite struggles with Black slavery, relationships with Native Americans reluctant to give away their homelands, and the U.S. Civil War than a resolution to actually travel to space, but I think it’s inspiring nonetheless.
Nancy and I visited the Cosmosphere in late May 2022.
The Cosmosphere (which is, again, smack-dab in the middle of Kansas) is home to the largest combined collection of U.S. and Russian spaceflight artifacts in the world. Numbering more than 13,000 pieces, the Cosmosphere’s collection is second to only the Smithsonian Institution’s Air and Space Museum for U.S. artifacts and is second only to Moscow for its number of Russian artifacts.
Given Kansas’s agrarian economy, it shouldn’t be a surprise that the Cosmosphere started as a planetarium, with a used projector and rented folding chairs, in the Poultry Building on the Kansas State Fairgrounds in 1962. It was one of the first public planetariums in the country. Four years later, the planetarium moved to the campus of Hutchinson Community College. In 1980, the Cosmosphere was expanded to a 35,000-square-foot facility, which included one of the country’s first IMAX® Dome Theaters and a three-level exhibit gallery (my first and only other visit to the Cosmosphere occurred sometime in the mid-1980s, while visiting family in Kansas). The Cosmosphere tripled its size in 1997, becoming an impressive 105,000-square-foot facility with room for educational events and other programs.
The German V-2 Rocket
The Cosmosphere has several large independent exhibits that tell the story of how the space race developed. One of these exhibits focuses on the development of the Vergetlungswaffe 2 (“retaliation weapon 2”), the V-2 rocket, and it’s simply an outstanding experience, with interesting displays of original hardware and plenty of explanatory panels.
It’s safe to say that putting mankind in space, beginning with launching manned rockets into the sky in the early 1960s, progressing to the Apollo missions to the Moon that started in 1969, and continuing with programs like Skylab (1970s), the space shuttles (1980s), and the present-day International Space Station, started with weaponry development during the buildup to World War II. Simply put, many of the other rockets exhibited in the Cosmosphere wouldn’t have been possible without the development of the V-2.
The Nazis sunk incredible financial resources into the development of the V-2, believing it would turn the tide of World War II because of its ability to strike opposing targets from more than 200 miles away. The V-2 was developed by a team led by Dr. Wernher von Braun, a brilliant rocketry scientist whose early work was influenced heavily by the tests performed by Dr. Robert Goddard (early in his career, von Braun corresponded with Goddard regarding the latter’s experiments). Von Braun was very interested in sending mankind to space, and saw the V-2 program as a way to further his research into rocketry. His interest in space exploration almost led to his execution by German officials, who believed von Braun wasn’t sufficiently focused on creating a weapon of destruction and instead wanted to create a way to travel to the stars. Only the doctor’s relationship with a Nazi official who had Hitler’s ear saved his life.
The V-2 was the first long-range guided ballistic missile. Between September 1944 and March 1945, Germany launched more than 3,200 of the rockets at targets in England, Belgium, and other areas in western Europe. The rockets were fired from mobile launch pads, which made it extremely difficult for Allied forces to find and destroy the launch sites. A V-2 firing battery consisted of 152 self-propelled vehicles, 70 trailers, and more than 500 men. Each battery could fire up to nine missiles per day.
A V-2 rocket stood more than 46 feet tall, weighed 27,000 pounds and flew 50 miles into the sky, but the engine was just over five feet long and weighed just over one ton. Incredibly, that engine created 56,600 pounds of thrust while burning 33 gallons of alcohol and liquid oxygen every second.
The rocket carried a one-ton payload of high explosives to the edge of space, 250,000 feet above the earth, more than 200 miles to its target. When it began its return to earth, the V-2 reached speeds of 3,500 miles per hour – faster than the sound that it created, which meant that it exploded on the ground before the thunderous roar of its descent could be heard. Latter-day research has shown that a V-2 explosion created a crater 66 feet wide and 26 feet deep, displacing about 3,000 tons of material. From launch, the V-2 took only 4 minutes to reach its target (for reference, the width of the state of Colorado is a little less than 400 miles, or about twice the distance that a V-2 traveled).
V-2 attacks killed more than 1,700 Belgians in Antwerp, and injured 4,500 more. In London, more than 2,700 civilians were killed by the rockets, with an additional 6,523 injured. As horrid as those numbers are, it’s estimated that development of the V-2 cost the lives of as many as 20,000 people in Germany – most of them Jewish prisoners who died either from overwork or from accidental explosions.
In its time, the V-2 was a defenseless weapon – when everything worked. Fortunately, the rocket involved incredibly complex engineering and everything rarely worked. While the Nazis continually refined the engineering to improve the weapon’s efficiency, the V-2’s development came too late in the war to have the kind of impact the Nazis expected. By war’s end, the development of the V-2 (and its predecessor, the V-1) cost Germany the equivalent of $3 billion – roughly twice the amount of money that the United States poured into the Manhattan Project to produce the atomic bomb.
World War II is ripe for “what-if” scenarios, and the V-2 development is a good one. Considering that the V-2 had an insignificant impact on the war’s outcome, compared to the carnage that occurred otherwise, the money and manpower that it cost could have been allocated to the production of more fighter aircraft and anti-aircraft missiles. If the Germans had better control of the skies over western Europe in 1944, the Allied invasion on D-Day may not have been possible and the slow but steady encirclement of Berlin by Allied and Russian forces wouldn’t have happened.
The exhibit at the Cosmosphere does point out, however, that if the invasion at Normandy hadn’t been possible, Berlin – rather than Hiroshima – may have been the first target of the atomic bomb.
In the immediate aftermath of Germany’s capitulation, both U.S. and Russian forces were on the hunt for von Braun and his team of rocketeers. Both sides wanted the expertise and equipment, but von Braun surrendered to the United States and he and his colleagues were brought to this country. The V-2 was examined and led to the development of the Cold War’s intercontinental ballistic missiles (ICBMs), and, in the interest of science, the rockets that would carry mankind into space beginning in the 1960s.
I’ve struggled – a lot – with how to write about this particular blog posting; it’s one reason I haven’t posted anything for several months, and I considered leaving all of the V-2 material out of it. However, I think it’s important to not shy away from the fact that humans can be horrible to one another. I’ve read a lot about German’s leading up to and including World War II, trying to understand why humans can be horrible. I’ve also read extensively about Wernher von Braun, trying to understand why he contributed his considerable scientific intellect to the development of a terrible weapon that killed thousands upon thousands of innocent people, either in targeted cities or in forced labor. Von Braun was absolutely furious that the Russians were first into space, first with a dog and then with a man, but he lived to see the results of the Apollo program that sent the first men to walk on the moon – using technology that von Braun helped develop while he worked at NASA. I’ve come to the conclusion (and it’s open for revision) that von Braun really did want to expand the science of rocketry – to send mankind into space – and he was able to do that. I’m a big proponent of many facets of space exploration, but I need to be more cognizant that much of that research has come at horrific costs.
There are a great many other fine exhibits (of which I took a lot of photos that seem to have disappeared into the ether; that’s probably okay because this posting would be even longer than it is) at the Cosmosphere, and it’s well worth a visit when you’re in central Kansas. I think I’ve written about this before, that museums like the Cosmosphere are a great opportunity to stretch one’s mind. Even if museums don’t have all of the answers, and, perhaps particularly if they sometimes don’t, it’s never a bad thing to learn.
It’s bold to call a town theBarbed Wire Capital of the WorldTM, but that is indeed what La Crosse, Kansas does. The designation came about because of another of La Crosse’s claims to fame: it’s the home of the Post Rock Museum. But before we get into post rocks, let’s go back to barbed wire (if you really want to read about post rocks, scroll down to the bottom of this post but you’re going to miss out on the truly exciting barbed wire content). In the early 1960s, volunteers at the Post Rock Museum noticed that a large number of visitors took special notice of the small barbed wire exhibit.
In response to that interest, in 1966 a group of La Crosse businesspeople formed the Kansas Barbed Wire Collectors Association. As with any association, it conducted an annual event: the first Barbed Wire Swap and Sell Convention occurred at the Rush County Fairgrounds in May of the following year. More than 2,000 barbed wire collectors and enthusiasts attended the show. La Crosse has since hosted the event each year (the 2022 festival was May 5-7) and that’s one way you get to be called the Barbed Wire Capital of the WorldTM.
Another way is to develop a museum. The first building that housed the Kansas Barbed Wire Collectors Association’s collection of barbed wire and associated materials was a small structure on Main Street in La Crosse. The museum was dedicated on April 30, 1971; the day included a parade as well as appearances and remarks from various local and state dignitaries. The 500-square-foot building was home to displays of 500 types of barbed wire, tools, and other artifacts, the majority of which came from the collections of two Kansas men, Leo Schugart of Hoisington and Don Wigington of Quinter.
Alas, less than two decades passed before the museum had outgrown the Main Street building. The La Cross chamber of commerce commenced a fundraising campaign to construct a new building, measuring 5,400 square feet, in the town’s Grass Park. The new facility, built in a year, was dedicated on May 4, 1991. The Kansas Barbed Wire Museum, which is owned and operated by the Kansas Barbed Wire Collectors Association, is also home to the Antique Barbed Wire Society’s Historical Research Center as well as its Hall of Fame. The museum welcomes visitors from around the globe each year.
Two of those visitors this year were Nancy and me, in late May. Nancy, recognizing my enthusiasm for barbed wire exhibits during our travels (we’ve seen an impressive number of exhibits in city museums in New Mexico and Arizona), surprised me with an early birthday gift of a visit to the museum. At the time, we were camping in Hays, Kansas, which is located about 25 miles due north of La Crosse. For those unclear or simply unaware of where Hays is, it’s about 160 miles east of the eastern border with Colorado, conveniently located in the north-central part of Kansas on Interstate 70.
You might be asking yourself: “Why is there a museum dedicated to barbed wire?” It’s a fair question, I suppose, and for the answer we must go back to the formation of the North American continent and its place on the earth. Imagine a vertical line hugging the eastern borders of North and South Dakota, continuing south near the eastern border of Nebraska, and then across the eastern thirds of Kansas, Oklahoma, and Texas. That line is the 98th Meridian, meaning that it’s 98 degrees (out of the globe’s 360 degrees) west of the Prime Meridian at Greenwich, England (all meridian lines extend north and south to the poles of the earth). The 98th Meridian is significant because most all of the land in the United States west of that line (with the exception of the Pacific northwest and the west coast) gets less (and some get much less) than about 20 inches of precipitation each year, and everywhere east of that line receives more than 20 inches. To compare five cities in which we’ve recently been:
Annual inches of precipitation
99th (one degree west of the 98th)
23.8 (plus an additional 13.9 inches of snow)
34 (plus an additional 33 inches of snow)
There are altitude-based and other geographic exceptions to the annual precipitation amounts, of course: a mountain town in Colorado such as Ouray, in the San Juans, can receive 20 or 24 inches of rain and almost 12 feet of snow each year. The point is, there are some places in the United States that are better suited to growing moisture-dependent crops such as, say, corn than others.
In the last year of being on the road, Nancy and I have experienced single-event rainstorms in Arkansas and Indiana that would have provided a third of Denver’s annual precipitation. That arid nature of the western United States results in different types of flora (such as buffalograss and saguaro cacti) and fauna (such as desert bighorn sheep and horned lizards), and, to get back to the subject of barbed wire, much fewer trees.
East of the 98th Meridian, trees are pretty common thanks to the arable soils and relatively high levels of precipitation. Because of their ready availability, trees provide wood with which to build fences to contain livestock and protect crops. However, in the high plains of the west, most trees grow naturally only along waterways like year-round rivers or seasonal creek beds; many of those trees, like cottonwoods and mesquite, are not anything with which you’d want to build a house or even construct a livestock fence.
While it doesn’t support any real kind of tree growth, the Great Plains does have a great variety of other plants. The native grasses of the prairies west of the 98th Meridian developed deep-growing roots in order to reach reserves of moisture in the soil. In addition to keeping the soil from blowing away during wind events, the grasses wouldn’t turn over easily with farm implements developed for eastern croplands. Further, those native plants had evolved to need much less moisture to survive than did crops such as wheat and especially corn that grew readily in the eastern United States.
Some of the earliest expeditions by the U.S. Army into what is known today as the Great Plains showed that the land probably wasn’t fit for much at all. In an 1810 journal recounting his adventures in the U.S. West, First Lieutenant Zebulon Pike wrote “these vast plains of the western hemisphere may become in time (as) equally celebrated as the sandy deserts of Africa.” Major Stephen H. Long, who traveled more than 26,000 miles in five expeditions across the West, in 1820 called the area “a great desert,” which later led to the term “the Great American Desert.” The plains area from present-day Nebraska south to Oklahoma was, according to Long, “unfit for cultivation and of course uninhabitable by a people dependent on agriculture.”
The passage of time shows that both Zebulon Pike and Stephen Long were wrong* about the prospects of people living in the High Plains. However, it took unimaginable hard labor, perseverance, and technological breakthroughs, in addition to that passage of time, to prove them incorrect. In 1820, the entire United States had a population of less than 10 million. Today, more than 14.5 million people live in the states of Nebraska, Kansas, Oklahoma, and Colorado. The Front Range of Colorado, which stretches from Pueblo in the south to Fort Collins in the north, has a population of more than 5 million people alone [and the Front Range also has views of two of Colorado’s most prominent mountains, Pikes Peak (elev. 14,115 feet) and Longs Peak (elev. 14,259 feet); I don’t know why the names don’t have possessive apostrophes, but these namesakes show that you can get mountains named after you even if you’re wrong].
*Actually, I don’t know that Pike and Long were entirely wrong. At least along the Front Range, that population of 5 million people is largely possible only by water being brought from somewhere else: snow runoff in western Colorado rivers that’s diverted under the Continental Divide to the Front Range, and water being pulled from the underground Denver Basin aquifer through wells. States downstream from Colorado are making increased (and, to this point, entirely legal) demands for Colorado’s western slope water, and the Denver Basin took tens of thousands of years to fill but is now being further depleted every year. Many farms in eastern Colorado and western Kansas and other parts of the area irrigate their corn (the crop doesn’t have much of a chance of success in the Great Plains without irrigation) with a lot of water pulled from the Ogallala Aquifer, which is being similarly and rapidly depleted, without a possibility of being refilled on a human timescale.
But I digress. Back to barbed wire. The 98th Meridian, then, served as a kind of barrier to westward expansion of the United States during and after the U.S. Civil War. The native grasslands were too tough to efficiently plow for use as cropland, and there was no guarantee that there would be enough precipitation to help crops survive even if their seeds could be planted. Add to that the fact that there was very little lumber for building or burning, and it was a land most inhospitable for development.
What was the land, which supported at the time only a number of nomadic Native American tribes that hunted immense herds of bison and other native animals, good for? Well, some folks decided it could support cattle. Between 1866 (the year after the Civil War ended) and 1880, nearly 5 million head of cattle were driven from Texas north into Kansas and beyond for transport by railcars back east.
Along the way, some cattle were sold to ranchers in Texas, as well as present-day Oklahoma, Kansas, and other states. Those cattle helped establish ranches that, in a few cases, are still around today. The Homestead Act, signed into law in 1862, brought droves of people to the west with the intent of acquiring free land upon which they could build homes and develop farms. Moreover, the railroads, in addition to transporting cattle east, brought more people from the eastern United States to the west where public sentiment thought it increasingly likely that livings, if not fortunes, could be made – despite the treeless aspect of the plains.
Those eastern sentiments, such as putting up fences to protect their crops and livestock, conflicted with the open range rights that the cattlemen enjoyed. However, the plains still weren’t any good at providing trees with which one could make fences. Until farmers could cost-effectively keep free-range cattle from tromping their crops and their own livestock from wandering away into the vast expanse of the plains, there was no way for livings to be made. That changed on November 24, 1874, when Joseph Glidden was awarded a patent for barbed wire.
Glidden (January 18, 1813 – October 9, 1906) was an Illinois farmer (I’m writing this blog posting at Kankakee River State Park in Illinois, about 90 miles southeast of Glidden’s farmstead in DeKalb) who developed one of the first methods of mass-producing barbed wire using a coffee mill to create the preliminary experimental barbs. With another twisted wire keeping the barbs in place, Glidden developed “The Winner,” which he considered his best design effort and for which he received the U.S. patent. The development was an immediate success and quickly found its way west, where, since much less wood was needed to build fences, it ended the open range era of the American west and it turned the Great Plains into innumerable pastures. When he died in 1906, Glidden was one of the richest men in America.
Today, drive along any road – multi-lane paved Interstate highway or dusty gravel byway – in the West and you’ll likely see galvanized steel barbed wire fencing that can stretch for miles on into the horizon. It’s cheap, durable, and relatively simple to install, without the use of much wood (except where there isn’t any wood; see below).
Glidden’s “The Winner” wasn’t the only barbed wire design, and many before and many after him developed their own styles that they thought would work better in certain situations or environments. Those hundreds of other barbed wire designs, all with the intent of keeping animals in (or out) of a certain area, kept and continue to help keep Americans and the world fed and clothed for generations – and that’s the reason there’s a Kansas Barbed Wire Museum.
What to Do When There’s No Wood
Prior to the coming of the railroads to the west in the late 19th century, vast tracts of lands in the west couldn’t be fenced because there were no trees with which to provide wooden posts and rails. Even after the continent was crossed and after barbed wire was easily available, wood was still scarce and therefore best reserved for building living and work structures.
But spools of barbed wire can’t be used to build a fence without some sort of solid material used for a post, so what do you do? In the case of central Kansas, you use readily available material: rocks. Present-day Kansas, like much of the rest of America, was once under a great inland sea. Over millions of years, organic material from recently departed marine creatures fell to the sea bottom, and over further millions of years was compacted into a rock called limestone.
The inland sea eventually drained away and, millions of years later, left present-day Kansas relatively dry and treeless under buffalograss-covered topsoil. Needing materials which which to build fenceposts, early settlers resorted to extracting the limestone rocks from just under the area’s topsoil. The area in which the limestone rests covers a 200-mile-long swath of Kansas land stretching southwest from the north-central border with Nebraska to about the location of Dodge City (a town, like many others in Kansas, that was made possible by the cattle trails of the late 19th century) in the southern part of the state. The swath measures in width from 10 to 60 miles wide. Farmers and people who specialized in quarrying post rocks would spend a day extracting about 25 posts, each of which could weigh between 200 and 450 pounds, from the ground.
Because of their strength and stability, post rocks were needed only every 30 feet or so to support a barbed wire fence. Today, with the ready availability of steel and treated wood posts, post rocks aren’t nearly as high in demand. But in their heyday, from the mid 1880s to 1920s, post rocks were found in 40,000 miles of fencing in that swath of central Kansas – and, because of their durability (they’re rocks), many are still in use.
Back to Barbed Wire
Barbed wire, at first glance, may not seem like a significant development. But without it, the expansion of Anglo-Europeans westward across the 98th Meridian would have been, at best, substantially delayed. Beyond the economics and geographic expansion, barbed wire had huge cultural impacts as well: because it disrupted the migration of bison herds, barbed wire also led to the displacement of dozens of Native American tribes that had considered the region their homeland for many generations. Barbed wire, with a solid assist from the railroads, is what made the Anglo-European development of the Great Plains possible.
The city of Colorado Springs is home to a number of U.S. military installations, including the U.S. Army’s Fort Carson; the U.S. Air Force’s Peterson Air Force Base, Schriever Air Force Base, and Air Force Academy; and the U.S. Space Force’s Cheyenne Mountain Station, Space Command, and Space Operations Command.
I spent some of my early years (1975-1979) growing up just south of Colorado Springs, and it was fun to be able to camp in the Goddard for a week in April a few miles from my childhood home. I’d forgotten how common it was to see people in military fatigues while walking around Colorado Springs: almost 10 percent of the population is active-duty military, and the defense industry is responsible for about 40% of the Pikes Peak region’s economy.
The U.S. military’s strong presence in Colorado Springs makes the city a fine host for the National Museum of World War II Aviation, which opened in 2012. The museum has a collection of 28 aircraft dating from the 1920s through just after World War II, and here’s what makes this collection unique: each of them still flies. Nancy and I have been to plenty of aircraft museums to see hundreds of aircraft, but this was the first one in which all of the aircraft could be taxied to a runway and take off. The airplanes are used in a number of airshows across the country, and therefore must be maintained to be reliable and safe in the air.
The non-profit museum is co-located at the Colorado Springs Airport with a private business called WestPac, which specializes in restoring and maintaining vintage aircraft. Our tour of the museum on April 29, 2022, also included a good look at what WestPac does to restore these beautiful birds and keep them in the air.
North American Aviation T-6 Texan
The Waco JYM doesn’t have anything to do directly with World War II but as is the case with all aircraft, its service record helped develop the technology used in later airplanes. The museum is right to be proud of having this airplane in its collection: it’s one of four Waco JYMs produced for Northwest Airways, and this 93-year-old aircraft is the only one still capable of flight (note the pan underneath the engine to catch oil – all of the aircraft in the museum’s collection have those). Mr. Lynch, a U.S. Navy veteran of the Vietnam War, provided a thoroughly educational and entertaining tour; he was able to speak not only about the mechanics required for powered flight from the viewpoint of an engineer, such as wing and propeller design, but also the global developments of World War II from a historical perspective. He’s one of the better docents Nancy and I have had the pleasure of meeting.
Douglas Aircraft Company SBD Dauntless
I don’t think Nancy nor I were prepared for how big these Navy planes were – I guess we’re just used to primarily seeing, in person at least, fighter aircraft that were used in the European theater of the war. An SPD-5 had a length of 33 feet, wingspan of 41.5 feet, and a height of 13.5 feet, all with an empty weight of 6,400 pounds. Interestingly, the Goddard, the fifth-wheel trailer in which we live, has a length of 35 feet and a height of just over 13 feet, but it has a dry weight of 14,000 pounds — it’s not expected to take to the air, though.
If you’ve seen either version of the movie “Midway” (the 1976 release with Charlton Heston or the 2019 edition starring a number of CGI pixels), the Dauntless is the airplane that gets the most screentime while showing the events of the battles of the Coral Sea and Midway. In the latter battle, these aircraft sank or disabled four Japanese aircraft carriers. Also serving in the Battle of Guadalcanal, the Dauntless was, despite its slow speed and relatively light armament, a very hardy and reliable dive bomber. These airplanes sank more enemy ships in the Pacific Ocean than any other World War II bomber. As aeronautic and armament technology increased rapidly during the war, the production of SBDs ceased in 1944.
It was a great experience to see an example of the aircraft that was able to so effectively counterattack the Japanese naval forces during the early weeks and months of the United States’ involvement in World War II. This particular aircraft has an interesting story: it crashed into Lake Michigan in May 1944, during aircraft carrier training exercises, and wasn’t extracted from the lake until the mid-1990s. It has since been restored to be a fully functional flyer, one of only six SBDs in the United States still capable of flight (one-tenth of one percent of the original total of 5,936 produced between 1940 and 1944).
Grumman TBM 3-E Avenger
TBF Avengers were not an immediate success story: of six unescorted aircraft that participated in the Battle of Midway in early June 1942, five were shot down and the sixth returned with one crewman dead and the other injured. As the war progressed, however, crews gained invaluable experience (each aircraft had a pilot, a gunner/radio operator, and a bombardier) and the Avenger played a pivotal role in naval operations; the airplanes destroyed two Japanese super-battleships and sank dozens of Japanese submarines in the Pacific and German U-boats in the Atlantic. The TBF/TBM had a maximum speed of 200 mph, with a range of 1,000 miles. It carried one 2,000-pound torpedo or 2,500 pounds of bombs, in addition to three .50 caliber machine guns and one .30 caliber machine gun.
George H.W. Bush, who would later serve as a U.S. President from 1989 to 1993, was shot down by Japanese forces during a September 1944 bombing mission while flying an Avenger. He parachuted from the plane and was picked up offshore by an American submarine.
Lockheed P-38 Lightning
This particular P-38, like many of the other aircraft in the museum’s collection, has an interesting history – including the deepest combat history of any other airplanes in the museum. Pilot Ken Sparks, on a mission on the last day of 1942, was credited with two aerial victories while flying this airplane. He downed one craft with gunfire, and then inadvertently clipped another with the Lightning’s right wing. The wingtip lost several feet of material, but the aircraft survived while the Japanese craft crashed. Sparks would have 11 more victories in several additional aircraft. This airplane was buried for decades near an airfield in Papua New Guinea, and was restored by WestPac in 2017.
This is another very large airplane, especially for a fighter, which made getting a good photo difficult – it has a wingspan of 52 feet. Empty, it weighs 12,800 pounds – twice the weight of the Douglas SBD Dauntless.
Republic P-47D Razorback
Republic P-47D Thunderbolt
Douglas A-1E Skyraider
Curtiss SB2C Helldiver
The National Museum of World War II Aviation is tremendously fascinating. Seeing a range of aircraft developed for both air combat as well as bombing was illuminating. It has fewer aircraft than most aviation museums we’ve seen, but the idea that all of the restored airplanes are still capable of flight really sets the museum’s collection apart. If you’re in the Colorado Springs area, the museum is well worth a visit – the aircraft there are really quite beautiful machines.
Progressing east and west, Interstate 40 divides Petrified Forest National Park into northern and southern sections. The interstate generally follows the path of historic U.S. Route 66, which connected the midwestern United States to the country’s west coast in the first half of the 20th century. Although Route 66 stretched more than 2,200 miles from Chicago to Los Angeles, Petrified Forest is the only national park with former segments of the historic highway within its boundaries. The area south of the interstate, much larger in size than the northern part, contains most of the petrified wood specimens in the park. The northern area, however, boasts incredible roadside vistas of the Painted Desert and a sizable national wilderness area. Nancy and I visited the northern part of the park in late March. Gunther stayed with Rusty in the Goddard, but Nancy and I would enjoy the dog’s company when we returned to the park the following day.
We briefly stopped in at the northern visitor center, which was undergoing significant renovation at the time, then proceeded to drive along a route that included a number of overlooks of Petrified Forest National Park.
I decided to use my 14mm wide-angle lens for taking pictures the day we visited the Painted Desert. I got it a couple of years ago to primarily take pictures of the night sky but thought its properties would help capture the feeling of the vast open landscapes of Petrified Forest National Park. There is a disadvantage to using this lens, though: it’s not automatic, so the aperture, ISO, and other settings all must be set manually. I’m no good at any of that. Many of the photos I took were over- or under-exposed, and I had to make manual adjustments using a couple of pieces of photo editing software.
Petrified Forest National Park contains only a small part of the Painted Desert, which stretches across almost 8,000 square miles of northeastern Arizona. The colorful rocks, primarily mudstone and sandstone, of this region are called the Chinle Formation. Deposited from 227 to 205 million years ago during the Late Triassic Period while most of the land area on Earth was on the single supercontinent Pangaea, the rocks have been buried, lifted, and eroded during Pangaea’s breakup and shift into today’s major continents.
During the Late Triassic Period, the land comprising Arizona’s Petrified Forest National Park was located just north of the equator and supported a much different environment (different enough, for example, to support a forest of 180-foot-tall trees that would later become petrified). As Pangaea divided, the land mass migrated north and the land itself underwent massive changes.
The Chinle Formation is itself divided into five members: Mesa Redondo, Blue Mesa, Sonsela, Petrified Forest, and Owl Rock. Each member represents a transition of the land from wet to dry environments over millions of years: the Mesa Redondo, the oldest layer and therefore the one underlying the rest of the formation, consists of red sandstone originally laid down 226 million years ago, and the youngest, Owl Rock, includes pink and orange mudstone at the top of the formation that was deposited 207 million years ago.
Older rock formations in the Painted Desert are at the bottom of the geologic column, and the layers of rock grow younger in age as the elevation increases. The colors of these rocks come from the iron they contain. Drier climates allow the minerals to become exposed to oxygen, causing the iron to rust and develop distinctive red, brown, and orange colors. When the climate is wet, moisture essentially covers the sediments and prevents their oxidation. Those layers are colored blue, gray, and purple.
Nancy and I took a short hike along the rim of the basin, and one of the highlights of that walk was a stop at the Painted Desert Inn, which was originally built as a respite for travelers on Route 66. The highway passed just a short distance south of the building, and a spur road brought visitors to the inn for refreshments.
The interior of the Painted Desert Inn now serves as a visitor center for the Painted Desert as well as a museum with artifacts from the inn’s heyday. It’s all very impressive and you’re going to have to take my word on that because none of the pictures I took inside turned out.
Despite my photographic foibles, we really enjoyed this first visit to Petrified Forest National Park. I grew up on the eastern plains of Colorado, and I know long, uninterrupted distances. They are nothing compared to what can be seen in northeastern Arizona.
We’d see more of the park, and a little bit of actual fossilized wood, the next day. (Actually, we’d see a lot of fossilized wood. So. Much. Fossilized. Wood.)
Holbrook, Arizona, located in the northeastern corner of the state, is the seat of Navajo County, which was split off from neighboring Apache County in 1895. Both counties are still huge: Navajo measures 9,960 square miles, and Apache still has more than 11,000 square miles even after the division. Navajo County is bigger than the state of Vermont and just slightly smaller than Massachusetts. (For reference, my home county in eastern Colorado, Kit Carson, is considered very large at 2,162 square miles; in fact, Navajo County is about a tenth the size of the entire state of Colorado.)
Nearly two-thirds of Navajo County is designated Native American reservation land, including parts of the Hopi Indian reservation, the Navajo Nation, and Fort Apache Indian Reservation.
We camped in Holbrook for a week because of the town’s close proximity to Petrified Forest National Park – the park is only 25 miles northeast of the city – but we found plenty to like about the town itself.
The Navajo County Courthouse, completed nearly 125 years ago, is now home to the Navajo County Historical Society’s museum. Built in 1898 at a cost of $15,000, including a $3,000 jail, the courthouse was in use until 1976 when the Navajo County Correctional Complex was constructed on the south side of Holbrook.
The museum was open on a Sunday afternoon in March after the Goddard’s arrival in Holbrook, so we were able to spend a few pleasant hours touring the exhibits.
The first exhibit in the museum is the county jail, which is to the right after one enters the courthouse. The jail was built in Kansas City, Missouri, by the Pauly Jail Company, which began operations in 1856 and is still in business today – be sure to consider it for any incarceration needs you may have. The jail was then shipped by rail to Holbrook and placed in the still-under-construction courthouse.
Firmly deciding to continue living our lives on the straight and narrow path, Nancy and I proceeded to other parts of the museum. Volunteers for the Navajo County Historical Society spend more than 2,000 hours each year curating and conserving artifacts from Holbrook’s past. The items represent the lives of Native Americans, Euro-American settlers, ranchers and cowboys, bankers, homemakers, railroad employees, teachers, merchants, and travelers through the area over the past centuries. Like many community historical museums we’ve visited, the exhibits in the building show a tremendous range of cultural, social, and economic pursuits. I wish other museums, however, were as well curated as Holbrook’s: the society has really done a fine job of keeping the exhibits relevant and reasonably sized.
The Mother Road
Holbrook makes much of its location on the former Route 66, one of the original highways of the U.S. Highway System. Established in 1926, Route 66 connected Chicago, Illinois, with Santa Monica, California, and passed through the states of Missouri, Kansas, Oklahoma, Texas, New Mexico, and Arizona in its 2,448 miles.
Route 66 was an extraordinarily important highway in the first half of the 20th century, serving as the primary means by which Americans migrated to the West – especially during the Great Depression (John Steinbeck’s novel “Grapes of Wrath” alludes heavily to the highway). The route proved to be an essential economic driver for dozens of cities and towns along the way, as businesses provided food, fuel, shelter, and services to those who traveled the highway. Route 66 was officially removed from the U.S. Highway System in 1985, having been mostly replaced by a variety of segments of the U.S. Interstate Highway System.
The Hashknife Outfit
In addition to the town’s Route 66 connection, the Holbrook museum also features extensive exhibits on the Aztec Land & Cattle Company. The company was founded in Boston, Massachusetts, in 1884 to take advantage of significant drops in cattle prices in Texas. Many large ranches in that state had continued to add to their herds, intending to reap profits when the beef markets improved. However, lingering drought caused prices to drop even further.
Aztec bought the Continental Cattle Company and its Hashknife brand (so called because the cattle brand resembled a bladed kitchen utensil), then shipped a total of 60,000 cattle and 2,200 horses from Texas to northeastern Arizona. The cattle were grazed on land purchased for 50 cents an acre from the Atlantic & Pacific Railroad. The grazing lands stretched about 300 miles from just south of Flagstaff to the New Mexico border (Arizona and New Mexico were both U.S. territories until 1912). With the ranch headquarters in Holbrook, the company’s employee base was a significant economic force for the town. However, Holbrook’s population of 300 residents found that not all of the Hashknife Outfit’s cowboys were of the law-abiding type. Cases of armed robbery and cattle rustling escalated, and there were 26 shooting deaths in 1886 (again, in a town of 300 people).
As was typical in the days of the Old West, range wars involving different ranches and their possessions were common. Many of the cowboys involved, either current or former Aztec employees, were incarcerated or outright killed.
The original end of Aztec as a beef-raising company came in 1902, with a drought, flooding, and overgrazing that destroyed the land on which the cattle were grazed. Aztec sold off its land and its remaining cattle, and the Hashknife brand was sold to a family in Flagstaff (and Aztec continues today as the third-largest private landowner in Arizona).
However, many of the cowboys of the Hashknife Outfit would go on to become respectable citizens of Holbrook and the surrounding area as independent ranchers, law enforcement officers, businessmen, and community leaders.
Although it was definitely the largest, the Aztec Cattle & Land Company wasn’t the only cattle concern around Holbrook and the museum has many artifacts about the ranching way of life.
Charles Goodnight, a Texas rancher and cattle trail developer, is credited with introducing the chuckwagon, a mobile kitchen used to keep cowboys’ bellies full, in 1866. Goodnight’s model was a modified wagon from the U.S. Civil War, to which he added a box with drawers and shelves for food and supply storage. Goodnight’s cattle drives took cattle from Texas to New Mexico on the Goodnight-Loving Trail (which also followed part of the Butterfield Overland Mail route). He’d later go on to drive cattle from New Mexico up into Colorado and Wyoming. Cooks for the cattle drives would also serve as barbers, dentists, and bankers for the outfits, and were so important that they were usually second in command to the trailbosses.
Back to the Triassic
One of the things I really appreciate about community historical museums is the breadth of items they display. The artifacts can range in dates from the times of ancient Native American cultures up to the Great Depression of the 1930s and even more recent. As I wrote, the Navajo County Historical Society has excelled at displaying just a few items from each era in order to abstain from overwhelming visitors. Let’s go back even further in time for a moment:
We enjoyed a one-week stay in Camp Verde, Arizona, in mid-March of 2022, which allowed easy access to two National Park Service (NPS) sites. The first was Montezuma Castle National Monument, a cliff dwelling on which construction began a thousand years ago and which we visited on a couple of consecutive weekday late afternoons. The second was Tuzigoot National Monument, another ancient Native American dwelling site located about 20 miles northwest of Camp Verde. Tuzigoot was declared a national monument on July 25, 1939. Nancy and I visited the monument on a pleasant but overcast Saturday in mid-March.
Like the nearby Montezuma Castle, the Sinagua Native Americans began construction on Tuzigoot pueblo about a thousand years ago. Also like Montezuma Castle, Tuzigoot is misnamed: it’s a corruption of the Tonto Apache phrase “Tú Digiz,” which means “crooked water” and refers to a bend in the nearby Verde River. The pueblo, located on a hilltop with 360-degree views for miles around the area, featured 110 rooms.
The proximity to Montezuma Castle, and to other pueblo communities like those in New Mexico’s Aztec Ruins National Monument and Bandelier National Monument, as well as Colorado’s Mesa Verde National Park, points to the fact that the residents traveled frequently between the dwellings and traded ideas and goods with each other. Again, much like the other pueblos in the area, the dwellings were abandoned beginning in the 1300s most likely due to a variety of reasons (depletion of natural resources, climate change, possible threats from other native cultures) rather than just one. Also, the Hopi, who count themselves among the Sinagua culture’s descendants, believe their forebears were naturally nomadic and didn’t like to stay in one place for too long.
The Tuzigoot National Monument experience begins with the site’s visitor center, which is itself a historic structure (although not as historic as the pueblo, since the visitor center dates only to 1936). The visitor center was built as a museum by local Clarkdale residents, who also helped professional archeologists with the initial excavation of the Tuzigoot pueblo. The center contains actual artifacts – not reproductions – that were found during the site’s excavation in the 1930s.
The visitor center is on the National Register of Historic Places and has a collection of 3,158 objects, not all of which are on display. The collection includes ollas (large pottery pieces serving as bowls or baskets), woven baskets, projectile points, and jewelry.
The Tuzigoot site was first described by Anglo-Americans in the 1850s but wasn’t professionally excavated for nearly a century after that. Following the departure of the Sinagua, centuries of neglect, along with countless rain- and snowstorms, freezing temperatures, and the desert heat, left the pueblo in severe disrepair. The site was first excavated in the early 1930s and Portland cement was used to stabilize the rocks. Unfortunately, that material can, over time, damage the original rocks used in the buildings. In the late 1990s, researchers began to replace the Portland cement with mortar that is a better match with the bonding materials that were used a thousand years ago during initial construction.
The 190-mile-long Verde River, which flows to the north and east of the Tuzigoot pueblo, drains an area of almost 6,200 square miles. The Verde flows just a few feet from where our campsite was in Camp Verde, which derives its name from the river. It eventually empties into the Salt River east of Phoenix, which in turn flows into the Gila River west of the city. A nice trail leads north from the Tuzigoot visitor center to a natural area called Tavasci Marsh (named after the family that once owned a dairy there). About 10,000 years ago the marsh was part of the river but it has since been separated through erosion and other geological forces to become a separate, but connected, wetland. There were, hundreds of years ago, many marshes in the Verde Valley. They’ve since been drained for human development and pasturelands, and today marshes are very rare in Arizona. The trail is a half-mile walk to an observation deck that overlooks the marsh, and there are more opportunities for birdwatching and plant appreciation.
Tuzigoot National Monument is a fine example of the diversity of ancient Native American pueblos. As conserved by the National Park Service, the monument is a great opportunity to not only learn about its former residents, but to also see some great natural attractions.
We’ve found that many museums and other attractions in the southwest allow visitors to bring their dogs along. That policy is probably, at least in part, so that people don’t leave their dogs in their cars. For whatever reason it is, we’re good with it.
Gunther was able to join us on the second of our two visits to the Pima Air & Space Museum in Tucson. The exhibits that we saw on March 6 were all outside. It was a lovely day and there happened to be an airshow training program taking place at a nearby airfield, so we saw plenty of planes on the ground and in the air. As I wrote in the posting about our first day’s visit, there are hundreds of airplanes on the grounds of the museum, and taking them all in, even with a two-day pass, is a lot to handle.
There are about 400 aircraft at the Pima Air & Space Museum, inside hangers and outside on the ground, and each of them has an interesting story to tell. I wanted to limit the number of photos in this posting to 10 or 12, but couldn’t decide what to exclude. I didn’t include photos of the EWACs (early warning and control) airplanes like the Grumman E-1 Tracer that flew over Europe during the Cold War, or the bombers like the couple of Boeing B-52 Stratofortresses on display. Even with the two-day pass, we could have spent a lot more time looking at these airplanes and learning about their place in history.
Nancy and I decided to pay a visit to the Tucson Botanical Gardens on a quiet Saturday morning in early March. The garden grounds are located in the northwest corner of the city, in a pleasant area of residential neighborhoods and small businesses. The gardens are at an expansive former family home, which adds a decided sense of intimacy to the experience of visiting.
We spent most of the morning wandering around the Cactus & Succulents Garden, which afforded us an opportunity to see some really interesting cacti and some birds as well.
The Cactus & Succulents Garden features plants from around the world that also perform well in the southern Arizona environment. The plants have been divided into four major areas representing the:
Sonoran Desert of North America
Chihuahuan Desert of North America
Desert regions of South America
Desert regions of Africa
Mexico has between 750 and 800 different species of succulents. The United States has about 200 native species, and South America has about a thousand species.
We saw a number of birds at the Botanical Gardens, including five species I’d never seen before.
We were really happy to visit the Tucson Botanical Gardens. It’s always fun to visit a garden that, like Denver’s, is in a residential area, and there were several more habitats in the gardens that showed even more diversity in plants. Even in early March, there were plenty of blooming flowers to enjoy throughout the gardens.
Until 1947, the U.S. Air Force was a component of the U.S. Army (during World War II the branch was known as the United States Army Air Forces). In 1966, during a celebration of the anniversary of the establishment of the U.S. Air Force, military commanders in the Tucson area realized that many of the historic World War II- and 1950s-era aircraft stored on Davis-Monthan Air Force Base were being lost – as was much of U.S. military history. Airplane parts were being sent to smelters so their metal could be used in modern aircraft production. Base officials began to set aside examples of the aircraft along the base’s fenced perimeter so that the public could see them. Although the practice saved many aircraft from the smelter, this wasn’t an ideal solution. The Tucson Air Museum Foundation of Pima County was formed that year, and the foundation found a 320-acre site of BLM land just south of the Air Force base. The foundation’s first aircraft acquisition was a B-24 Liberator. Many years (and hanger constructions and aircraft acquisitions and hanger expansions) later, the Pima Air & Space Museum is the country’s largest non-government-funded aviation museum. The museum has more than 100 civilian, military, and experimental aircraft in its four indoor hangers (totaling a quarter-million square feet) alone, as well as many more parked on the grounds outside for a total of about 400 aircraft.
Recognizing that its collection is large and takes aircraft enthusiasts a lot of time to visit, the museum smartly offers a two-day pass that Nancy and I took advantage of. Because March 4 was pretty breezy, we opted to spend that day looking at the aircraft inside the hangers. I’ll share just a few of the ones that I enjoyed viewing, listed in order of their year of introduction.
Even if it represents a smaller percentage of its total collection, the aircraft inside the hangers of the Pima Air & Space Museum are truly impressive. They’re historic, they’re beautiful, and some of them are terrifyingly efficient at what they were designed to do. There were dozens of other aircraft that I didn’t include in this posting: a McDonnell FH-1 Phantom, a Grumman F-14 Tomcat, a Hawker Hurricane, a Grumman F-11 Tiger, a Fairchild-Republic A-10 Thunderbolt … the list of aircraft just under a roof at this museum is incredible. Seeing a Huey up-close again, as well as other aircraft that my dad has flown, was really rewarding. Here’s a fun fact: my birth in June 1969 was induced a few days early so Dad could see me before leaving for Vietnam. I was born in McPherson, Kansas, where my two great-uncles (the B-24 Liberator crewmen) were friends a quarter-century before I was born.
In another post, we’ll return to the Pima Air & Space Museum and take a look at the aircraft outside the hangers (some of which my dad has also flown).
