An agricultural area immediately south and southeast of Phoenix shows cultivated fields whose crops use water provided by an extensive irrigation network. Barely discernible are the west-flowing Gila River and streambed; the northwest-flowing Santa Cruz River; and smaller stream drainage channels across the desert landscape. Also discernible are the southern end of the Maricopa Mountains, southwest of Phoenix, and the darker, brown hills and low mountains that are scattered throughout this arid region. The Gila Bend area is barely visible at the upper right corner of the photograph.
