Tonto National Monument Nature and Science

Situated within rugged terrain at the northeastern boundary of the Sonoran Desert, Tonto National Monument preserves cliff dwellings and other archaeological sites of the prehistoric Salado. For three hundred years, a vast culture lived within the Tonto Basin, surviving and adapting to the arid environment. Built in shallow caves, perched over a thousand feet above the river valley, the cliff dwellings are representative of the final phase of occupation in this area.

The river valley below, once a thriving settlement with farm fields and stone dwellings, is now covered by Roosevelt Lake. The surrounding mountains built by sedimentary layers and then uplifted, are continually being shaped through erosion and weathering. From the valley rising 2000 feet to the mountain tops, spreading through open areas, sheltered among rocks, nestled in canyons, and hidden among washes are different local environments, each with their own community of wildlife. This is the tremendous diversity and interconnection of life that is the Sonoran Desert.

This area of the desert experiences hot summers. Both people and wildlife are more active during the cooler morning and evening hours. Cool winters are an active time for the monument. Many animals are more visible during the day and visitation by people is much greater. Even with two rainy seasons, the average rainfall is only fifteen inches. Storms entering the valley sometimes leave moisture and other times just pass on through to other places.

Through the play of light and shadow, vistas change -- hour by hour, season by season. Within the dwellings themselves, or looking out over the valleys and steep slopes of surrounding mountains, the ever-changing scenes emphasize the need to guard the resources of this desert environment.

The pika is a close relative of the rabbits and hares, with two upper incisors on each side of the jaw, one behind the other. Being rock-gray in color, pikas are seldom seen until their shrill, metallic call reveals their presence.
