After World War Two

Preservation and Visitor Services

After World War II, national and international visitation to national parks and monuments grew. Facilities were needed, and the first park ranger house was constructed in 1950. Visitation that year reached 17,700 and the need for modern facilities increased. The old parking lot, which accommodated 6 to 8 cars, was expanded in 1950 to help with growing traffic. Funds for excavating and stabilizing the Lower Cliff Dwelling were received and archeologist Lloyd Pierson undertook this work; evidence of this historic stabilization project is still visible today.Interpretive signs were installed along the Lower Cliff Dwelling and Cactus Patch trail. Thousands of visitors came to see the dwellings.

In 1951, a concrete water tank was built in Cave Canyon to store water from the nearby spring. Water lines were laid to the visitor use area and down the canyon where ranger housing would soon be built. The days of rangers sleeping in tents and visitors using outhouses were over.

By 1960, Phoenix's population was 438,000. Major highway projects in Arizona had opened up the country, with Route 66 bringing people west by the millions. Visitation at the cliff dwellings for 1960 was documented at 46,000.

Mission 66- National Park Service 50th Anniversary

Barely keeping pace with growing visitation, In 1956 the National Park Service devised a 10-year plan to upgrade facilities in numerous Park Service sites. In 1964, as part of Mission 66, a building which housed the Visitor Center, Museum, and administrative functions was constructed. The construction of the Visitor Center was completed in 1965.
Mission 66 would transform Tonto National Monument into a 20th century preservation and educational facility. Construction of the new Visitor Center was a declaration that the cliff dwellings were now stable and could be enjoyed by all.

National Historic Preservation Act

In 1966, President Lyndon B. Johnson signed the National Historic Preservation Act (NHPA) into law and formally recognized historic preservation as an important policy of the United States. As a result, Tonto National Monument was automatically placed on the National Register of Historic Places. This register identifies and documents significant historical and cultural sites to facilitate their preservation.

Visitor Services and Resource Management

In 1970, visitation at the park exceeded 53,000 people. Now, modern facilities awaited visitors which included displays on the archeological findings at Tonto National Monument. In 1974, the entrance road and Lower Cliff Dwelling trail were paved.

In 1985, archeologist Martyn Tagg completed the first systematic archeological survey of the entire monument. The object was to locate, record, and evaluate all archeological significant remains within the Monument boundaries and provide a full picture of its archeological resources for the first time.

In 1998, the National Park Service's Vanishing Treasures program was established. The Vanishing Treasures program supports the preservation of traditionally-built architecture in the Western United States, facilitates the perpetuation of traditional skills, and promotes connections between culturally associated communities and their places of heritage. Tonto National Monument was among the first to secure Vanishing Treasures funds for personnel and projects.
