March 14 & 15, 2022 – Near Camp Verde, Arizona
Having nothing at all to do with Montezuma, the early 16th-century emperor of the Aztecs (known now as Moctezuma II), nor a castle in any sense of the word, Montezuma Castle National Monument is still a very rewarding site to visit.

Because access to enter the actual structures is limited to those who really need to go in them, the park also focuses a lot on native species of flora found in the region and provides a lot of interpretive signage next to examples of plants to explain how the plants were used by the occupants of the dwellings. As an (extremely) amateur botanist, this was fine by me.

We were able to make a couple of late weekday visits to fully explore this monument, which is located just a few miles north of our campground in Camp Verde, Arizona. It was also the first opportunity for Gunther to earn a B.A.R.K. Ranger certification (more on that later).

The structures in the monument were built by the Sinagua, Native Americans who migrated to this area about 1,400 years ago and began building the cliff dwellings about a thousand years ago – hundreds of years before Moctezuma II was born. The current name of the monument, Montezuma Castle, comes from European Americans who in the mid-1800s were extremely interested in the Aztec, Mayan, and Incan cultures of present-day Central America and wanted to bestow exotic names on nearly everything they found.

The cliff dwellings are built in Verde Formation limestone, a relatively soft sedimentary rock. Over millions of years, the erosional forces of water and wind have had their way with the limestone to carve many holes into the rock. The erosional holes that are enlarged by humans into structures are called cavates by archeologists. At Montezuma Castle, most cavates extend about 10 feet into the cliff. By closing up naturally open spaces, and building exterior and interior walls with masonry, the Sinagua were able to construct secure housing for their culture.

The Sinagua built and occupied the dwellings between the years 1100 and 1425, leaving the residences about 70 years before Columbus set sail. Montezuma Castle was at the crossroads of a Native American trading network that stretched from the coast of present-day California to eastern New Mexico, and from Utah into Mexico. That central location provided the Sinagua with many resources that weren’t available in the Verde Valley:
- Obsidian, used for projectile points, came from the San Francisco Mountains north of the castle
- Wild game and plants were taken from the Mogollon Rim, located east of the structure
- Strong trading relationships with the Hohokam culture, in present-day southern Arizona, provided much more than was available in the Verde Valley
Contrary, perhaps, to popular opinion, because of that trading network the Sinagua had an awareness of their world that stretched for thousands of square miles.
Where the Sinagua went, and why, after about the year 1425 is still up for debate, but most researchers believe the exodus was due to at least one of three factors: drought, depletion of food resources, and threats from newly arrived cultures.
The Hopi culture, which may be descended partially from the Sinagua, believe this structure wasn’t meant to be the final home of their ancestors. When a culture stays too long in one place, the Hopi believe, environmental disasters and societal collapses remind them of their migratory nature – and they move on. The Zuni and other Puebloan groups are also said to be descended from the Sinagua.

Between 1991 and 1994, an inventory of the plants and animals at this national monument was taken by a team of researchers from Northern Arizona University and the United States Geological Survey. That research resulted in the cataloging of 784 species of plants and animals in this 859-acre (less than 1.5 square miles) site; only 11 percent were non-native species.


Looters of the 19th century took many of the contents of the structures, and today the ruins are open only to scientists for research, inspection, and maintenance. This is in contrast to Gila Cliff Dwellings National Monument in southwestern New Mexico, in which visitors are allowed to enter the structures. Part of that policy us is perhaps due to proximity. Gila Cliff Dwellings National Monument is one of those places you have to want to get to, since it’s nearly a two-hour drive from the closest large city; Montezuma Castle is just a couple of miles off Interstate 17 in central Arizona. About 350,000 people visit Montezuma Castle each year; Gila Cliff Dwellings gets about 42,000 visitors annually.


Montezuma Castle National Monument was established by the administration of U.S. President Theodore Roosevelt. During his administration (1901-1909), five national parks, 18 national monuments, 150 national forests, and 51 bird sanctuaries. In all, Roosevelt authorized a total of 230 million acres (almost 360,000 square miles) for the enjoyment of future generations like ours.

We didn’t see much in the way of wildlife while at the monument (Nancy and I were both surprised at the number of late-day visitors each day, but that was probably due to the monument’s easy access from the Interstate); however the habitat’s diversity (holes in cliffs to dry meadows to riparian areas) supports all kinds of bats, foxes, mice, owls, songbirds, snakes, lizards, and turtles.

Being open only to researchers is also due to the fact that ladders must be used to access the cliffside ruins: the buildings were definitely at least partially planned with defense in mind. Additionally most of the cliff faces south, which allows the dwellings to be warm in the winters and cool in the summers. The elevated location also protects the dwellings from occasional flooding of Beaver Creek, which flows beneath the cliffs.







The National Park Service has a pretty nifty program in which dogs can earn their B.A.R.K. Ranger certification in certain parks and monuments. Gunther knows, and you should too, that B.A.R.K. Rangers:
- Bag your poop. Always have your humans bag and dispose of your waste properly.
- Always wear a leash. When in the park, always wear a leash (6 feet or less) and don’t let your humans leave you unattended.
- Respect wildlife. Don’t harass or harm wildlife by making noise or chasing them.
- Know where you can go. B.A.R.K. rangers are permitted in parking lots, campgrounds, picnic areas, roads, and designated trails.


The B.A.R.K. Ranger program is really clever: it keeps dogs out of hot vehicles while their owners visit national parks and monuments, while encouraging those owners to be responsible for their pet. Since that great day at Montezuma Castle, Gunther has also earned B.A.R.K. Ranger certification at Petrified Forest National Park, also in Arizona, and Pecos National Historical Park in New Mexico. Look for future blog postings about those visits and more, and look for Gunther on the trails!
