Tonto National Monument

▪ cliff dwellings, Arizona, United States

      cliff dwellings located in the Tonto Basin of southeastern Arizona, U.S. They lie 110 miles (175 km) east of Phoenix, in Tonto National Forest. Between about AD 1150 and 1400, the Salado people—a farming culture named for the Rio Salado ( Salt River), which flows through the valley—established permanent apartment-style residences by constructing clay walls in shallow, naturally eroded alcoves within the hillsides. Ranchers and soldiers came upon the ruins in the 1870s, and in 1907 President Theodore Roosevelt (Roosevelt, Theodore) proclaimed the site a national monument. Tonto is a Spanish word meaning “fool.”

      Major features of the 1.8-square-mile (4.7-square-km) monument are the Lower Ruin, consisting of a 16-room ground floor with some second-story rooms and a neighbouring 12-room annex, and the Upper Ruin, which has a 32-room ground floor, a second story, and terraces and rooftop space. Although some of the rooms are well-preserved, exposure to weather has taken a toll. Traces of irrigation canals (now flooded by Theodore Roosevelt Lake, impounded by a dam on the Salt River) and other archaeological evidence indicate that the Salado cultivated crops such as corn (maize), beans, and cotton. They wove the cotton into exquisite textiles and created decorated red clay pottery. They also made excellent use of the native plants of their desert environment—saguaro, yucca, prickly pear, mesquite—for food, tools, clothing, baskets, and construction materials, and they hunted mammals, birds, and reptiles. Wildlife in the area includes deer, coyotes, jackrabbits, javelinas, Gila monsters, and rattlesnakes. Additional plants include creosote bush, palo verde, agave, and, along the river, Arizona black walnut. The monument's visitor centre displays pottery and other artifacts.
