Population Growth in the Southwest


Four years after Bandelier's visit, population in the Arizona Territory began to increase rapidly. People were brought west first by wagon trains and trail rides then by the Southern Pacific Railroad which came to Phoenix in 1887. Business and industry followed. By 1900, Phoenix's population was 5,554.

With a growing population, farming, water, and flood control in the Southwest became an issue, thus setting in motion a series of events that would have dramatic effects on the cliff dwellings and their future.

Water and the Roosevelt Dam

Phoenix suffered through numerous catastrophic floods as the Salt River ripped and tore through ineffective earthen dams. Water storage, availability, and control had reached their limits. The Salt River Water Users was formed and, with other states and territorial delegations, lobbied Congress for action. In 1902, President Theodore Roosevelt signed the National Reclamation Act authorizing damming of western rivers; the Bureau of Reclamation was created and the Arizona Territory was selected for the first dam. By 1903, plans were in place to build Theodore Roosevelt Dam at the confluence of Tonto Creek and the Salt River.

Located just four miles from the construction site, the cliff dwellings felt the impact. Workers, their families, and sightseers began exploring the cliff dwellings. Rare photos of this period show change in the dwelling's conditions through the early 20th century.

Tonto National Monument

What was happening to the cliff dwellings was occurring across the American Southwest. Due to a growing concern over the destruction and looting of archeological sites, the American Antiquities Act was passed in 1906. This act authorized the president to establish monuments for places of natural and cultural significance. Areas such as Devil's Tower, Montezuma's Castle, Gila Cliff Dwellings, Chaco Canyon and many more were given protection under the Antiquities Act.

The Roosevelt Dam project and associated completion of the Apache Trail made the Tonto cliff dwellings a popular attraction. As their popularity grew, sentiment and concern for their future had grown as well. On December 19, 1907, President Theodore Roosevelt signed Proclamation 787, creating Tonto National Monument. Four hundred and eighty acres surrounding the Lower and Upper Cliff Dwellings were set aside and placed under the authority of the U.S. Forest Service.

Southern Pacific Railroad

Roosevelt Dam was completed in 1911; Arizona became a state in 1912. By then, the Southern Pacific Railroad had constructed a hotel near the dam and was offering tours. Tonto National Monument was one of the highlights on their Apache Trail Tour.

In 1929, in cooperation with the US Forest Service, the Southern Pacific made a road to a large parking area at the mouth of Cholla Canyon, where the current picnic area is located. A pit toilet was dug, and a 1-mile trail was cut to the Lower Cliff Dwelling. Ray Stevens was hired as caretaker and was paid $30 a month to serve as the first maintenance person and tour guide.

By 1932, Tonto National Monument had become a popular tourist destination. The Southern Pacific extended the dirt road to where the current parking lot is and built a stone caretaker's house.

For the next three decades, this structure served as the Monument's Headquarters, Visitor Center, and Museum. Chain link fences were erected and locked at night to control access at the dwellings. Fences helped, but unknown numbers of people entering these unstable areas damaged the cliff dwellings. The Tonto Cliff Dwellings suffered more damage and loss in the 1920's and early 1930's than during the previous 600 years.

By 1932, Phoenix's population had grown to 48,000. A growing road system allowed exploration of central Arizona by automobile and an estimated 100 people a month were climbing through the cliff dwellings.

National Park Service Early History

The official history of Tonto National Monument dates from 1907, but the period of protection and preservation began in July 1933. On that date, Tonto National Monument was transferred from the Department of Agriculture, U.S. Forest Service, to the Department of Interior, National Park Service.

Charlie Steen was the first National Park Ranger assigned to Tonto. During 1934, Steen was assigned to spend time at many newly established monuments.

Rangers in this remote area lived in tent houses and drew water from the local spring. Flooding, scorpions, rattlesnakes, and hard work were part of the daily routine. As primitive as the conditions were, Steen and the rangers that followed persevered. The road was improved and a trail was cut from the parking lot to the cliff dwellings. Archeological and biological studies were initiated to better understand the cliff dwellings and the surrounding environment. A park ranger could now be present at the cliff dwellings to inform visitors of the Monument's archeological value and protect what remained of the fragile structures.

Also in 1934, the Gila Pueblo Archeological Center took samples from the timbers in the dwellings for dating purposes. Dendrochronology, or tree ring dating, is a method of using growth rings on trees as a calendar in order to date archeological sites.

The first indication of how many people were visiting came in September 1935 when Steen reported 305 people for the month. Read Steen's Monthly Reports.

In 1937, President Franklin D. Roosevelt added 480 acres to the Monument. Eventually, nearly 70 archeological sites were discovered on the now 1120 acre preserve.

Preservation and Visitor Services

Establishing facilities, preparing trails, and stabilizing the cliff dwellings were routine activities conducted by rangers. In 1937, the Lower Cliff Dwelling was excavated and stabilized for the first time by William Duffen, a graduate student from the University of Arizona.

In 1938, more than 5,000 visitors came to Tonto National Monument. Infrastructure was basic at the time and rangers made do with what they had or what they could borrow. By today's standards, ranger housing was little more than camping out.

Charlie Steen returned in 1940 to stabilize the Upper Cliff Dwelling. Published in 1960, his "Excavations at the Tonto Cliff Dwellings" is the earliest detailed report of architecture and artifact observations at the cliff dwellings. With the asisstance of the Civilian Conservation Corps Navajo “Mobile Unit,” they were able to stabalize those walls and build that trail.
