Nancy, Gunther, Rusty, and I are wintering in Las Vegas, Nevada. We arrived here at the beginning of November 2024, with plans to depart in early spring of this year. There are worse places to spend the winter than Las Vegas: the campground at which we’re staying is surprisingly inexpensive with friendly folks and lots of activities, there are a lot of good restaurants and entertainment options relatively nearby, and, as we found out last winter (we spent five months here), there are a unexpectedly large number of hiking and birding opportunities very close to the city.
Gunther, Nancy, and I took advantage of one of those birding opportunities during the waning days of 2024 with a visit to Clark County Wetlands Park, located just a few minutes’ drive from our campground. The Las Vegas Wash, which I described in last year’s posting about the Owl Canyon Hiking Trail at Lake Mead National Recreation Area, creates the wetlands aspect of the park. Those of you who have spent much time in the desert city of Las Vegas might be surprised to see that a decent-sized creek runs through the east side of the metropolitan area. Las Vegas Wash is bigger at times, especially after heavy rains, than others. For those used to even small-sized creeks and rivers, it’s probably not a very impressive waterway. However, the Las Vegas Wash is absolutely critical for the health and sustainability of this area; the water in it is collected wastewater and runoff from the city’s hotels, golf courses, and other businesses, as well as residential wastewater and stormwater runoff, on a 12-mile journey (including through wastewater treatment plants) to the Lake Mead impoundment east of Las Vegas. Ninety percent of the water used in the Las Vegas metropolitan area is drawn from Lake Mead (the rest is from groundwater sources), so it’s imperative that as much water that’s used in the city gets returned to the reservoir as possible.
We’re currently close enough to the Golden State that I thought this might be a California quail as opposed to a Gambel’s quail (Callipepla gambelii), but it is indeed the latter. It, along with three or four more of its kind, was hunting on the ground just off the trail shortly after we started our walk. In addition to southern Nevada, this bird’s range includes regions of California, Arizona, New Mexico, and Utah, as well as little parts of western Colorado.
Whether it’s moving, still, salty, fresh, or freshly treated, water makes a huge difference in supporting wildlife populations; without the wash, many species of birds, lizards, and mammals simply wouldn’t be in this place. That fact was made clear to us on the day that we visited. Like most avid birders, I keep a record of each bird species we see during the year. Before we began the five-mile loop walk through the wetlands, we’d seen 50 different bird species in 2024; by the time the three of us climbed back into the Goddard’s six-wheeled towing unit to drive back to the campground, we’d seen 18 additional species, 12 of which were species not yet seen in 2024, and four of which we’d never seen before. In other words, nearly a quarter of the bird species we saw in 2024 were seen on the on the 363rd day of the year during this 2 1/2-hour hike just outside of Las Vegas.
Much of the 2,900-acre (4.5 square-mile) Wetlands Park is a nature preserve, into which Gunther (very understandably) can’t go. However, there’s a very fine concrete trail that skirts the outer perimeter of the preserve and also goes over a bridge that crosses the wash. It was from that bridge that we saw three of the four “lifers,” or bird species we hadn’t ever seen before.
This is a view from the Las Vegas Wash looking west toward Las Vegas Boulevard, or “The Strip.” It was an overcast and hazy day in the Las Vegas Valley, but you can just barely make out some of the structures on The Strip. Mandalay Bay Resort and Casino, the southernmost casino on The Strip and indicated by the green arrow, is about nine miles directly west of this position. The Stratosphere Hotel, Casino and Tower (I think it’s just going by The STRAT now) is indicated by the blue arrow and is located about six miles to the north of Mandalay Bay. (Incidentally, at 1,149 feet the Stratosphere’s observation tower is the tallest in the United States and is second in the Western Hemisphere only to Toronto’s CN Tower at 1,815 feet – but that’s a conversion from metric so who knows what’s really going on?) Anyway, the Spring Mountain Range is on the horizon, and in between Las Vegas Boulevard and the mountains is Red Rock Canyon National Conservation Area, which we visited last winter. Those are American coots swimming in the Las Vegas Wash on the right.We’ve seen lots of little white-crowned sparrows (Zonotrichia leucophrys) since becoming full-time RVers, especially in New Mexico and Arizona, but it’s always a pleasure to see (and hear) them again. Of all the little brown birds (LBBs), they are one of the easiest o identify. Small but mighty, these birds are exceptional migrators and have been tracked flying as many as 300 miles in one night.
Prior to becoming full-time RVers and when we still lived in Denver, Nancy and I visited Las Vegas at least once a year. Like most visitors, we arrived via airplane at Harry Reid International Airport (née McCarran International Airport), and took a cab to our hotel, either on The Strip, or, later and more regularly, in downtown Las Vegas. We’d spend a few fun-filled days, some more profitable than others, and then take a cab back to the airport and return home. A lot of people don’t realize that when they fly into Harry Reid International Airport, spend a few days recreating on The Strip then return to the airport to go back home, they’re not ever actually in Las Vegas – unless they go to the Stratosphere (I don’t care what it’s going by now; I’ll still call it the Stratosphere because I just got used to not calling it Bob Stupak’s Vegas World) or to downtown Las Vegas. Otherwise, each of the roughly 40 hotels and casinos, including places like The Bellagio, Caesar’s Palace, New York New York, The Luxor, The Wynn Las Vegas, and dozens more) along Las Vegas Boulevard, with the exception of the Stratosphere, is in unincorporated Clark County (as is the airport). Those hotels have a total of nearly 89,000 rooms (The Wynn Las Vegas alone has almost 4,800 rooms); compare to, say, downtown Denver which has about 11,000 hotel rooms and the biggest one, the Sheraton Denver Downtown, has 1,231 rooms). The point is, there are a lot of hotel rooms in Las Vegas (and tens of thousands more in unincorporated Clark County), and all of them have bathrooms with showers and flushing toilets, and all of that water needs to go somewhere.
Where it needs to go is into Lake Mead, and how it gets there is via the Las Vegas Wash. Wastewater treatment plant facilities clean up the water as it makes its way to the reservoir; during our visit to the wetlands on December 28, I was reminded of walking and biking on the Cherry Creek Regional Trail in Denver because of the unmistakable (and not entirely unpleasant – certainly more pleasant than it had been before) smell of wastewater under the process of being treated.
Anyhow, and as someone once wrote, back to the birds.
Here’s the first of the never-before-seen-by-us species: the Crissal thrasher (Toxostoma crissale). It’s very similar to a curve-billed thrasher, but the Crissal’s beak is even longer (and more curved, I think). This particular species prefers to stay on the ground, foraging for food, rather than fly about to fill its belly. In the United States, this bird is found only in the southern parts of California, Nevada, Arizona, New Mexico, and far western Texas. I usually avoid editing my pictures, other than cropping and re-sizing, but I decided to adjust the contrast on this one to bring out the bird better. The overcast conditions on the day we visited weren’t the best for photography, and many of the birds were far away (in the nature preserve, where, thanks to Gunther, we weren’t allowed. Thanks again, Gunther.)Happily, the sun happened to be out a bit more when we were on the bridge in Wetlands Park, and I got what I think are some pretty good photos. These ducks were far enough away that I didn’t know what species they were until we got back home and I could have a closer look at the images. This is another new-to-us species, the ring-necked duck (Aythya collaris). As is sometimes the case, the identification feature that’s in the name of this species isn’t really helpful in identifying it: the ring on the neck is very faint, and was probably more visible to early naturalists on captured birds. As a migrator, this species is found throughout North America in different parts of the year; during the fall, Minnesota lakes supporting beds of wild rice can sometimes have flocks of ring-necked ducks numbering in the hundreds of thousands. In this species, as with many other ducks, the male (right) and female (left) genders have remarkably different coloration most of the year (note the extreme difference even in their eye color). As was pointed out to me a few days ago by a full-time resident of this campground, the females of many bird species have to stay more camouflaged to protect the young hatchlings (in that case, we were talking about hummingbirds, but it’s true for many bird species). We’ve had the opportunity to see plenty of double-crested cormorants (Nannopterum auritum), especially at St. Vrain State Park in northern Colorado, but they were usually swimming. For some reason, there were a lot of cormorants on the wing this day at Wetlands Park. This one is showing off its wingspan, which can get to four feet long. Interestingly, despite being a water bird, cormorants do not have waterproof feathers – it’s why they’re often seen on shore with their wings spread. I recently listened to a very interesting audiobook about the Cretaceous-Paleogene Extinction Event, in which an asteroid struck the Earth 66 million years ago and brought the Age of Dinosaurs (mostly) to an end. The author consistently mentioned, though, that only non-avian dinosaurs, or those reptiles that couldn’t take to the air, were made extinct. I’ve mentioned it before, but double-crested cormorants (the white crests appear above the eyes of adult birds only during the breeding season) are one of the best reminders that, in an indirect way, avian dinosaurs still populate the earth.I’ve long been struck by how majestic and powerful most birds look when viewed from the side, or perhaps a three-quarter angle, and how they don’t look at all majestic and powerful when viewed face-on. This is a great blue heron (Ardea herodias), which spent a considerable amount of time among the reeds on the hunt for small fish.The angle makes all the difference: same exact bird. Great blue herons are a lot of fun to watch – they’re very patient while hunting and move almost imperceptibly, but then strike lightning-quick to pull fish from the water. If you look away for a moment, you may have missed all of the action. GBHs grow to a height of almost 4.5 feet and can weigh 5.5 pounds, with wingspans measuring more than 6.5 feet.I originally thought this was a snowy egret (and thus a lifer), but when editing the photo for this posting I realized that its beak is all yellow and its legs are all black (and it’s overall bigger than a snowy egret, which have black beaks and yellow legs). Thus, it’s a great egret (Ardea alba), which we’ve seen plenty of times elsewhere but are still very gratifying to watch. This bird is the symbol of the National Audubon Society, which was created to save this species and others from extinction. Because of their white brilliance, the feathers of great egrets were once valued as decorative accessories for people. This one was just taking off from creekside of the Las Vegas Wash, affording a good view of its feet just above the water. Again, this bird was far enough away while I was photographing it that I wasn’t really sure what species it was, but upon getting home and reviewing it on a bigger screen I discovered that it is an American bittern (Botaurus lentiginosus). This, the third of the “lifer” birds for this walk, was flying about the wash looking for a good place to land. They weigh between 13 and 17 ounces (just over a pound), with a three-foot wingspan. In true Vegas style, we were lucky to see this bittern while on the wing; this species is somewhat rare to observe in the wild because it takes advantage of that striping pattern on its neck and chest to hide motionless among reeds and other tall waterside plants while hunting. American bitterns, also migrators, are found from central and southern Canada down into Mexico at different parts of the year. During the winter months in North America, this species is found only in the extreme southern parts of the southern states and along the eastern and western seaboards. That’s an American coot on the right. We’ve seen American wigeons (Mareca americana) before as well, most memorably near Willcox, Arizona, but it was good to see another one near Las Vegas. We didn’t see any wigeon drakes; only this hen; drakes have a green head and a white crown. Wigeons’ bills are shorter and more goose-like than those of other dabbling ducks, and for that reason more of their diet is plant-based than those of other duck species. That’s an American coot on the right.Compare this egret to the great egret pictured above: notice the black beak and the yellow feet of this one? That’s right: it’s a snowy egret (Egretta thula), and thus the final lifer of the day! Another difference between the two species is their size: great egrets can grow to a height of just over 40 inches and a weight of 35 ounces, while snowy egrets only grow to about 26 inches and a weight of 13 ounces. Regrettably, and although I waited for what seemed like a reasonable time, no American coots made their way into the background of this photo.The “wetlands” aspect of Wetlands Park ends pretty abruptly; in fact, within just a few feet of the water’s edge, the landscape reverts back to extraordinary desolation. The Las Vegas area is in the extreme northeast corner of the Mojave Desert, 54,000 square miles of a dry and sparsely vegetated area that also includes Death Valley. The desert gets between 2 and 6 inches of rain each year, and summertime temperatures regularly climb into the 120-degree-Fahrenheit range. Still, there’s plenty of opportunity for my favorite desert plant, creosote, to grow (although these are, by far, the lowest-growing creosote bushes I’ve ever seen). We’re facing away (east) from the Las Vegas metropolitan area in this view. Yonder, about 20 miles beyond those picnic shelters, lies Lake Mead.Nancy was the first to spot this Say’s phoebe (Sayornis saya) as it flitted about in the shrubbery to our left (well, if Gunther saw it first, he sure didn’t point it out to me). The bird seemed to want to follow us down the trail for a while, giving me plenty of opportunities to snap its picture. These birds are found only in the western United States and Canada, and most of Mexico. They’re actually fairly gregarious, as birds go, and will often roost in buildings. Their diet consists mostly of insects. It’s possible that their name will change sometime in the future: there’s a movement in the birding community to re-name all birds that are named after individuals because it turns out that some of the individuals for whom birds have been named after were not themselves very nice people. Dunno if that’s the case for American naturalist Thomas Say (1787-1834); I do think that individual names are on their way out just for consistency’s sake.The walk that Nancy and Gunther and I were on was a balloon loop, in which you start walking and sooner or later make a left or right turn, then keep walking until you get back to the point at which you made a turn (completing the loop) and then walk back to the start of the hike (completing the “string” of the balloon). This allowed us to make a repeat visit to the bridge under which the Las Vegas Wash ran, and gave us another opportunity to see birds attracted by what the water makes possible – basically, fish and bugs and waterplants. The overcast and hazy conditions of the day were already pretty bad, and the mid-afternoon sun was fading, too, but I did get a few pictures of this belted kingfisher (Megaceryle alcyon) perched over the wash. This photo, too, has been edited to bring out the contrast and colors of the bird. This photo still isn’t that great; the white spot above the kingfisher’s bill is just that: a white spot, and its eyes are black and above and just behind those spots. We’ve seen exactly two belted kingfishers, which is a flying marvel of a waterbird, since we became full-time RVers a little over three years ago. Both of them were seen in Las Vegas, which averages about four inches of rain each year (we saw the other one last winter at another wildlife preserve in Las Vegas proper; I’ll get around to writing about that super-cool place someday). Water really is a crucial aspect of wildlife diversity. We were highly fortunate to see this one actually fishing; it’s an laccomplished flyer and is capable of quickly diving down to the water to catch fish and crawdads with that magnificent bill.We’re nearly to the other end of the bridge now, and running out of water in which to see waterbirds. The ducks to the left, of course, are mallards (Anas platyrhynchos), including the drake at far left and the hen in the middle. Mallards are found all over North America, Europe, and parts of Asia and even Africa. I read recently that domestic ducks (the familiar white ducks of many a barnyard) are domesticated from the mallard species, and the mallard genome is so prevalent in ducks that it’s prone to cross-breeding in wild populations that some species struggle to remain distinct. This lovely couple gives a good size perspective on the snowy egret at right – they’re really not very big, are they?Alright, alright … one more bird before we leave the waterway. This is the fabulous American coot (Fulica americana), which, although it floats like a duck is more closely related to sandhill cranes than anyone in the duck family. I wasn’t going to include this, but there were (obviously) about three kajillion coots on the Las Vegas Wash that day and it doesn’t seem right to exclude an exclusive photo. This is, incidentally, the best picture of a coot I’ve ever taken; their black color and tendency to hide amongst water plants makes them difficult to photograph well. This was probably the biggest bird we saw during our walk. It’s hard for me to resist taking pictures of aircraft flying overhead, even while enjoying the serenity of nature. This is a Boeing 737 Max 8, registration number N17341 and operating as United Airlines Flight 1981, shortly after its scheduled departure from LAS (Harry Reid International Airport) at 2:05 PM Pacific time, with scheduled arrival at EWR (Newark Liberty International Airport in New Jersey) at 9:59 PM Eastern time. N17341 saw a lot of the country on December 28: it left Charleston International Airport (CHS) in South Carolina at 6:00 AM Eastern, flying first to EWR, then flew cross-country to LAS, then had this flight back to EWR. More than 1,050 flights arrive at and depart from LAS every day; it’s the country’s eighth-busiest airport.
The next couple of photos aren’t from the Las Vegas Wetlands Park walk – they’re ones I took in our campground in which we’ve been staying the winter. There’s not necessarily a lot of variety of birds here, but they’re still fun to keep an eye out for.
I often see this little dude, a male Anna’s hummingbird (Calypte anna), when Gunther and I are visiting our campground’s dog park in the mornings. While Gunther is attending to his business, I look to this same little branch on this same little tree, and about half the time he’s there, just about 10 yards from the dog park’s fence. The legs of all hummingbirds are so small that the birds can neither walk nor hop on the ground or on a branch. They, like all hummingbirds, are tiny: Anna’s have all the volume of a ping-pong ball and the all the mass of a shiny U.S. nickel (between a tenth and two-tenths of an ounce). As small as they are, they’re powerful fliers: males can soar up to 130 feet in the air. This species of hummingbird, one of 360 in the world, is found year-round in the Las Vegas area, as well as the western halves of California, Oregon, and Washington. Say, that reminds me: I’ve recently learned the German word for “pineapple” is “Ananas,” so the imperativ (command) for “Anna, eat pineapple!” in German is “Anna, esse Ananas!”Here’s another reminder that we share this planet with dinosaurs’ descendants: imagine the slashing terror of these razor-sharp talons, the brute strength of these powerful claws, the raw crushing horror of …… a rock pigeon (Columba livia), which is found year-round all over North, Central, and South America, and the campground in which we are spending the winter.Gunther thanks you for joining him (and Nancy and me) on this Las Vegas Wash adventure, and hopes you have a healthy and happy 2025 filled with lots of fun walks!
Here’s a list of the birds (not all are pictured above) we saw at Wetlands Park; it was one of the more successful birding walks we’ve ever enjoyed, and just a fun way to spend an afternoon in The Entertainment Capital of the World.
About 190 million years ago, much of the present-day southwestern United States was covered in an immense field of sand dunes – one of the largest that has ever existed on the planet. Many of the dunes happened to carry iron pigment, which turned red when it was oxidized by the sun.
Over the course of millions of years, and with the help of chemical compounds like calcium carbonate and iron oxide, the dunes were slowly cemented into a rock called Aztec sandstone.
These sandstone formations are the primary feature of Red Rock Canyon National Conservation Area, located only about 15 miles west of the casinos, hotels, nightclubs and other delightful debauchery of Las Vegas, Nevada. The area includes nearly 200,000 acres (about 300 square miles) of the Mohave Desert, and it’s visited by 3 million people each year – a little less than what Yellowstone National Park in Wyoming receives.
It’s an impressive number of visitors, to be sure. I think, however, that most of Red Rock Canyon’s visitors are from the Las Vegas area. Its canyons and sandstone cliffs make it remarkably unlike most of the rest of the flat desert surrounding the city, and it’s extremely popular with hikers, cyclists, and rock climbers. Consider that Las Vegas’s Harry Reid International Airport (until 2021 McCarran International Airport) saw almost 58 million passengers arrive and depart in 2023, and it’s easy to see that most of those people aren’t coming to The Entertainment Capital of the World to entertain themselves by visiting a national conservation area.
Being avid hikers with interests in geology and biology, Nancy and I (and Gunther) went to Red Rock Canyon National Conservation Area in early December 2023. We were happy to be joined by a Canadian couple we met at the campground in Las Vegas at which we were staying; it turns out that Canadians enjoy hiking as well. They also joined us for a visit to the Hoover Dam, a hike in Lake Mead National Recreation Area, and a hike in Valley of Fire State Park north of Las Vegas (not all on the same day).
A one-way scenic drive, a loop 13 miles in length, at Red Rock Canyon provides many pullouts and parking lots with access to hiking trailheads (beginning a total of 22 trails ranging in length from under one mile to more than 10 miles), overlooks, and other points of interest.
It’s easy to see how Red Rock Canyon got its name. The sand originally forming the dunes contained an abundance of minerals, one of which was iron that was oxidized by the elements over millions of years. The area began its federal protection in 1967, when the Bureau of Land Management (BLM) designated 10,000 acres as the Red Rock Recreation Lands. Further legislation over the years and significant additions of acreage eventually led to the National Conservation Area designation in 1990.I was struck by the clear delineation of colors in the rock. These two different colors of rock are both types of sandstone, but water moving through the sand at the bottom millions of years ago took away the red minerals and left behind calcium carbonate. The sand later developed, over even more millions of years, into sandstone.Erosional forces like water and wind result in some really cool-looking rock formations. Note, also, that the light-colored and red layers of rocks are the reverse of the photo above (and I didn’t post it upside-down).These huge sandstone blocks are not naturally formed: they’re remnants of one of the earliest industries in the Las Vegas area. The Excelsior Stone Quarry began operations in 1905, extracting blocks of sandstone for use as building materials. The blocks, some weighing up to 10 tons, were pulled with a 17-ton steam-traction engine to the just-built railroad in Las Vegas and loaded onto railroad cars bound for Los Angeles and San Francisco, where they served as decorative building material. While the sandstone was judged to be of exceptionally fine quality, quarries closer to California’s coastal cities were later developed and the Excelsior Stone Quarry and other operations in the area shut down for good in 1912. The plant growing in front of the large block is a species of yerba santa, which is Spanish for “sacred herb.” The name comes from the plant’s medicinal properties to treat respiratory and digestive ailments – even today, yerba santa extracts can be found in western U.S. herbal medicine stores.Part of the day included a hike on the Calico Tanks Trail. The long views and beautiful multicolored rock formations along the trail reminded Nancy and me of several places in Colorado, including Garden of the Gods in Colorado Springs and the Red Rocks Amphitheater near Morrison. Two hikers can be seen in the lower-left corner of this image. The BLM has classified the Calico Tanks Trail as “moderate”; I’d say, based on the elevation gain and necessity to scramble up and over rocks, it’s on the far end of “moderate.” It was a beautiful hike, though.These curves in the sandstone were created while the materials were still in the form of loose sand. Wind blowing across the dunes created these lifted layers before the grains of sand were cemented into the sandstone of today.This specimen of Spanish dagger (Yucca schidigera, also known as Mohave yucca) reminded us that we were in the desert. It, like many plants found in the Mohave and other deserts, looks pretty savage.Speaking of savage, Gunther takes a break on the Calico Tanks Trail to enjoy the scenery. He got along really well with the Canadians; he gets along really well with pretty much everyone, no matter their country of origin.This is the feature for which Calico Tanks Trail gets its name: a seasonal pond, or tank, created by water seeping or flowing into a depression in the sandstone (there was a much smaller water feature earlier in the trail, thus the plurality of the trail’s name). The Spanish word for this formation is “tinaja,” which means “clay pot.” The sun on this early December day was pretty low in the sky, making for some considerable shadows from the rock formations. Those of you who have been to Las Vegas will probably think this tank is the third-largest standing body of water in the area after Lake Mead and the fountains in front of the Bellagio resort on the Las Vegas Strip; I would not disagree with that assessment. Formations like this make possible a huge diversity of plant and animal life that otherwise couldn’t survive in the desert.If you squint, the hotels and casinos of Las Vegas can just barely be made out near the horizon in this image, taken at the end of the Calico Tanks Trail. This vantage point took some rock scrambling to get to; along with my phone, with which I took this and most of the rest of the photos in this posting, I was also carrying my digital camera with a large and heavy zoom lens in case we saw any wildlife. A fellow hiker noticed the camera and said I was brave for bringing it along; I corrected him and said I was dumb.So that I didn’t bring my heavy camera lens on the Calico Tanks Trail for naught, here’s a picture of a rock climber I took with it. Rock climbing is a pastime in which I have absolutely no interest in participating.Yeah, this looks like just heaps of fun. The BLM’s website states that rock climbing at the national conservation area is among the best in the world. Red Rock Canyon National Conservation Area is one of more than 850 areas managed by the BLM’s National Landscape Conservation System, which totals 27 million acres of areas designated as National Conservation Areas, National Monuments, Wilderness Areas, Wilderness Study Areas, Wild and Scenic Rivers, and National Historic and Scenic Trails.Longtime readers of this blog know that I won’t pass up an opportunity to post an image of lichen. I have no idea what species this is, but I think the shade of green is best described as “obscene.” Together with wind and moisture, plants and lichens do their part to erode the rocks into all kinds of fantastic formations.This is a view from High Point Overlook (elev. 4,771 feet) looking east toward the city of Las Vegas, which is 15 miles on the other side of the rock formation. High Point Overlook is just a little shy of the midway point of Red Rock Canyon’s scenic drive. The vegetation in the foreground gives an idea of what the flat parts of the area are like; it appears kind of sparse, but it’s much more heavily vegetated than other areas we’ve seen around Las Vegas. There are about 600 species of plants found in the conservation area, a number boosted considerably by the presence of year-round water: the sandstone allows water to percolate, creating springs, pools of standing water like the Calico Tanks, and even small creeks and waterfalls .This is Turtlehead Peak (elev. 6.323 feet), also photographed from High Point Overlook. There’s a trail to the top, but it’s 5 miles round-trip with a 2,000-foot elevation gain, and Gunther didn’t want to try it so we didn’t. That’s a heavily laden Utah juniper (Juniperus osteosperma) on the left, with Mormon tea (Ephedra nevadensis) growing at its base.I wasn’t planning to see any natural bodies of water in Red Rock Canyon National Conservation Area, let alone one that was flowing. This is Lost Creek, along which we saw a huge diversity of plant life flourishing in early December. I will remember this very short hike off the scenic loop for a couple of reasons: this stream, and the fact that Nancy bonked her head on a low-hanging ponderosa pine branch that was overhanging the trail; she didn’t see it because of her hat brim. If she hadn’t been in the lead of our hiking party, any of the other three of us would probably have bonked our heads (even though he was ahead of Nancy, Gunther didn’t bonk his head because he’s an expert hiker. And he was able to just walk under the branch, without making note of the obstruction to Nancy.) We’ve discovered that the maintenance of trails in the federal system can vary greatly; BLM trails are perhaps the most … rustic. It’s really not a problem, and I’m certainly not complaining. It’s just interesting to see.Here’s an example of the diversity of plant life in Red Rock Canyon National Conservation Area: a specimen of ashy silktassel (Garrya flavescens), growing along Lost Creek. I’ve never knowingly seen it before. It can grow up to about 10 feet high. Another short trail from the scenic loop leads to a grouping of petroglyphs and pictographs, created by native Americans thousands of years ago. The minerals in rock exposed to the intense desert sun over the millennia develop a dark patina called desert varnish. The native Americans removed the patina with stone tools to expose the lighter colors of the original rock beneath, creating designs known as petroglyphs. Pictographs, in contrast, are designs created with paints made with clays, charcoal, and other minerals, and then applied to the rocks.Here’s a closer view of the petroglyphs in the photo above this one. The meanings or significance of these designs have been lost to time; the only communicative records of the people who created these designs that still exist are the petroglyphs themselves. Nancy and I have seen quite a few petroglyphs in New Mexico and Arizona, but it was a bit surreal to see these ancient designs just 15 miles from the (barely) controlled 24-hour party of the Las Vegas Strip.Here’s an example of a pictograph, or an image painted on the rock, located just a few yards away from the petroglyphs. It’s a little hard to see in this photo, but petroglyphs and pictographs are themselves sometimes hard to see in the wild. There’s a closer view of the pictograph below.The pictograph looks like a figure 8 with a vertical line inscribed through it (it’s just to the right of dead center in the photograph above). Again, we have no idea what its significance is, but it must have been important to someone a very long time ago. The BLM and other federal agencies take great care to protect these cultural artifacts; like in other areas around the country, the precise locations of many of the pictographs and petroglyphs in Red Rock Canyon are not made available to the public. Six major groups of native Americans have lived in what is now Red Rock Canyon, beginning with the Tule Springs Paleo-Indian culture 11,000 to 8,000 years ago.
A visit to Red Rock Canyon National Conservation Area had been highly recommended by one of our Lyft drivers who happened to be a native of Las Vegas, and she was right to do so. I mean, we would have gone regardless, but our visit definitely blew past what I thought it would be like. I sure wasn’t expecting to see those incredible views, enjoy fascinatingly colorful rock formations, and go on a hike next to a running stream, let alone appreciate imagery left by native Americans thousands upon thousands of years ago, but Red Rock Canyon had all of that and more. If you do find yourself in the Entertainment Capital of the World and want to experience something completely unlike what Las Vegas is known for, Red Rock Canyon National Conservation Area is a wonderful place to spend a day.
Lake Mead National Recreation Area Near Las Vegas, Nevada – January 6, 2024
Impounded behind the concrete and steel of the magnificent Hoover Dam, Lake Mead in southeastern Nevada and southwestern Arizona is, by volume (and when full), the largest inland reservoir of water in the United States. There are a couple of U.S. reservoirs that have a larger surface area, but they don’t have the depth of Lake Mead (when full). The reservoir, made by the result of damming the Colorado River, is the primary feature of Lake Mead National Recreation Area – the nation’s first NRA as well as its largest at 1.5 million acres, or just over 2,400 square miles. For perspective, Lake Mead NRA is a couple hundred square miles larger than Kit Carson County in far eastern Colorado.
When full, Lake Mead has a surface area of 247 square miles, a surface elevation of 1,229 feet above sea level, and a maximum depth of 532 feet. When it’s full.
Lake Mead is, at the moment, not full. Not even close, really. In fact, it’s a couple hundred feet below its capacity, and it hasn’t been this empty since it was first filled after the construction of the Hoover Dam in 1937. A multi-decade-long drought in the southwestern United States, as well as unprecedented demand for agricultural and municipal water in the multi-state region served by the reservoir, have led to a stunning drop in the water level of Lake Mead. The reservoir’s capacity is so large that one inch of water in the lake equates to about 2 billion gallons. Two billion multiplied by 2,400 inches (200 feet) means Lake Mead has 48 trillion fewer gallons of water since the reservoir was last full in the mid-1980s. That number is so large as to be effectively useless, but in terms of acre-feet (which is the amount of water needed to cover an acre with 12 inches of water), Lake Mead is currently a little over a quarter of its capacity.
Geologists and hydrologists, along with other concerned -ogists, are working, and have been working for several decades, to address this issue. Many millions of people rely on Lake Mead’s water to continue flowing through the reservoir, providing electricity as well as drinking, municipal, and agricultural water. Mother Nature, while a powerful force in her own right, will take a long time to refill the reservoir: even after the remarkable upstream snowpack of the 2022-2023 winter in the Rocky Mountains, the reservoir rose only a few inches. It would take many consecutive decades of consistently above-average snowpack to refill the lake. That’s highly, highly unlikely to happen.
While the situation awaits a hopeful solution, that change in Lake Mead’s water levels also presents new opportunities for recreation: the receding water has left behind areas for great hikes. Recreation managers have developed at least 14 hiking trails all around the area, ranging from short and easy strolls to a 34-mile-long bike loop to strenuous hikes that are meant for the truly hardy among us.
Which neither Nancy, nor Gunther, nor I, are. We lucked into a great hike called the Owl Canyon trail on the first weekend of 2024, and saw some pretty cool sights while enjoying a 4-mile out-and-back trail.
We saw several of these beautiful buttes along the trail to Owl Canyon. The creek flowing below the butte at lower left is Las Vegas Wash, a 12-mile-long arroyo that channels most of the excess water from the Las Vegas metropolitan area into Lake Mead. The wash contains water from urban runoff, reclaimed water from golf courses and parks, and stormwater; in short, it’s probably best to not dip your tin cup in it for a cool, refreshing drink – although the plants and rocks of the wash do filter a lot of the contaminants out of the water before it reaches Lake Mead. This photo was taken perhaps a half-mile from the trailhead, which was a boat ramp that used to provide watercraft with access to Lake Mead. More on that later.Thousands of these small white mollusk shells can be found in several locations along the Owl Canyon trail. They point to a time, years ago, when this entire area was covered by a vast body of water: Lake Mead, which, when it’s full is about 60 percent bigger than the area covered by the city and county of Denver. As recently as the 1980s, mollusks like these were free to frolic or fritter away their days or whatever it is that mollusks do. Now, every foot of the trail we were on is high and dry.
Here we see an intrepid hiker and her ill-behaved dog (it’s Nancy and Gunther) approaching the mouth of Owl Canyon, about a mile and a half from the trailhead on the boat ramp to the west. The canyon can also be accessed by a trailhead resulting in a shorter hike (2.2 miles out and back) coming from the northeast, but we wanted a bit more of a challenge for this first hike of 2024.
As you can probably tell from the earlier photos, it’s rather arid in the Lake Mead National Recreation Area (it’s in a literal desert, the Mohave, and the region is a convergence of the Mohave, Great Basin, and Sonoran deserts). Depending on which resource you use for reference, the area gets between 4 and 6 inches of precipitation each year. Except for a great blue heron, a small family of mallard ducks, and a large flock of goldfinches, we didn’t see much in the way in wildlife on the day’s hike. However, we did see some examples of desert plants that we hadn’t yet encountered on our travels. This is a specimen of desert stingbush (Eucnide urens), also known as velcro plant. It’s found in the desert regions of the southwestern United States and Baja California. It looks a lot like holly leaves seen around the December holiday, but, true to its name, the serrated leaves have stinging hairs to protect the plant from browsing animals. It’s yet another desert plant one wouldn’t want to lick (although the desert bighorn sheep native to the area seem to like them quite a lot).The walls of the canyon, which were under the waters of Lake Mead for many years, is made of a conglomerate of many different kinds and sizes of rocks, ranging from particles of sand to basalt stones the size of footballs or larger. Owl Canyon existed before Lake Mead; it was carved by an intermittent watercourse to create a winding natural path through the desert.The previous photo of the canyon walls’ conglomerate was taken near a spot in the canyon where we stopped for lunch. This photo was taken from the same spot. It shows Gunther alertly listening to Nancy about further instructions regarding the hike, especially to be constantly aware of impending threats from wildlife. (He’s really just waiting for Nancy to offer him some of her tuna salad sandwich; ultimately, he was disappointed to be denied the same.) The bandana he’s sporting around his neck was acquired gratis from a pet grooming service in Idaho over the summer; it looks like I neglected to iron it before we left on that day’s hike.Owl Canyon gets its name from the many holes in the rock walls that have eroded away, providing perches for owls and other roosting birds. Walking through its winding course was a ton of fun, although Gunther appeared to be ready to leave at any time.Of course, Gunther was right to be terrified. One drawback presented by the canyon’s winding rock walls was the inability to see anything around an upcoming bend, such as these remarkable multi-stone sculptures located just before a culvert in the canyon, until they suddenly appear before you. They were encountered on our return path through the canyon; they weren’t there when we walked through the culvert earlier and gave us something of a start. Their sudden appearance shall forever remain a mystery. (Seriously, a family also walking through the canyon must have put quite a bit of work into stacking these stones, and they did it in pretty short order. Park managers are strict when it comes to building even small piles of rocks: like graffiti on rock walls or otherwise defacing natural resources, despite how cleverly they’re designed, putting these formations together is forbidden.) That’s Lakeshore Road above the culvert.Here are Nancy and Gunther on the other side of the culvert pictured above. Walking through its galvanized confines as we hiked underneath Lakeshore Road was an interesting experience. I found, to Nancy’s delight, that it provided quite an echoing experience. There are two culverts in Owl Canyon; they allow seasonal water runoff to continue on its natural course through the canyon on its way to Lake Mead.Erosion from water and wind creates some spectacular rock carvings. Vertical formations like this, like the much larger butte pictured earlier, are created when the erosional forces of water and wind take away rock material surrounding a structure, but the formation itself is protected on its top by a layer of less permeable rock. I’d guess that this formation at the top of the canyon wall is 12 to 15 feet tall.Nancy and Gunther emerge from the canyon and prepare to return to the trailhead; Gunther, in particular, appears pretty happy to be out. That’s a brittlebush (Encelia farinosa) plant in the lower left, displaying its bright yellow blossoms on this early January day. Perhaps unsurprisingly, brittlebush is a member of the sunflower family.On our walk back to the trailhead, we saw this striking shrub we hadn’t noticed while hiking to the canyon. I inset a closeup of the plant’s leaves in the lower right. It’s a pretty plant, isn’t it, with its deep red limbs and attractive dark green and juniper-like leaf structures? Don’t be fooled! This is the scourge of the southwest, an invasive plant called tamarisk (Tamarix ramosissima) that’s native to Europe and Asia. Land and river managers throughout the southwestern United States spend a lot of resources trying to control the spread of tamarisk, the flowers of which each contain thousands of tiny seeds. Younger tamarisk plants compete with native plants for water along riverways; tamarisk doesn’t grow well in shade, so if the native plants are able to outgrow tamarisk (which can grow to heights of 25 feet in full sun and with sufficient water), the natives will usually win out. This particular plant was growing quite a ways from Las Vegas Wash.This is a view of the length of the boat ramp that now serves as a parking lot for a couple of hiking trailheads, including the Owl Canyon Trail. I took this photo as we were driving away from the trailhead. You can barely make out the white paint on a couple of vehicles parked on the right side of the ramp near its end. Las Vegas Wash is just beyond the end of the ramp. When the lake is full, a lot of this ramp would be underwater. Keep scrolling to see what it would take to get this boat ramp functional for launching boats into Lake Mead again.Here’s some perspective of how low Lake Mead is. This is a screenshot from Google Maps, using satellite imagery taken from about 250 miles above the earth, of the area in which Nancy, Gunther, and I hiked. The boat ramp pictured in the photo above this screenshot is the small gray strip in the upper left corner; we parked the Goddard’s six-wheeled towing unit approximately where the red dot is. Owl Canyon is in the red circle; we hiked from the boat ramp, to and through the canyon, and back again. Las Vegas Wash is the creek at the top of the image flowing into Lake Mead in the upper right corner; when the lake was full, it extended west all the way to cover a lot of the boat ramp on the left side of the image. In short, the end of the boat ramp is at least three miles from the current waters of Lake Mead, and the lake would still need to fill much more in order to actually launch a boat from the ramp. When we finished our hike we happened to meet an construction engineer on the boat ramp who was doing some preliminary evaluation to prepare for its eminent demolition and extraction of the concrete, rebar, and other materials. As he told us, “This lake isn’t filling in our lifetimes.”
It’s easy to think that it’s not the end of the world if Lake Mead continues to dry up: the Colorado River flowed freely through this area for millions of years, supporting all kinds of native plant and animal life. But that’s not the world in which we currently live, and the disappearance of Lake Mead would be an absolute catastrophe: without constant flowing water to turn Hoover Dam’s turbines, many metropolitan areas in the southwest, like Phoenix, Las Vegas, and Los Angeles (to say nothing of the many thousands of smaller cities in the region), would suffer calamitous losses of electricity as well as a reliable source of water. Simply put, water impoundments like Lake Mead (and, to lesser but still vital extents, Lake Powell and Blue Mesa Reservoir upstream) make habitation of the southwest possible. Ain’t nobody living in Phoenix or Las Vegas in the 120-degree temperatures of July without air conditioning provided by electricity, to say nothing of being able to turn a faucet and expect water to come out.
It’s sobering to think that every step we took on this hike was once well underwater in Nancy and my lifetimes. Fortunately, smart and committed people are working on ways to continue developing and encouraging water conservation in the American southwest, but committed people will also need to actually take those steps in order to keep water flowing through Lake Mead.
