Yuma, Arizona, U.S.A. February 1994 This photograph of part of the Sonoran Desert, which includes southeastern California, southwestern Arizona, and a small section of Mexico, shows the great extent of crop irrigation in the floodplains of the Colorado and Gila Rivers. The outline of the small desert city of Yuma and some circular center-pivot irrigated fields to its south are discernible near the center of the photograph. Several natural features are visible�the elongated northwest-southeast-trending Sand Hills in southeast California; the merging east of Yuma of the west-flowing Gila River and the south-flowing Colorado River; and the low, heavily mined Gila Mountains southeast of Yuma.
