FIGURE 14.1 Algodones Dune Field, Sonoran Desert, near the California-Mexico border. Algodones Dune Field is about 10 km
(6 mi) wide and 70 km (45 miles long). The long axis of the dune field is oriented northwest-southeast, along the direction of the prevailing
northwest winds. Notice in this astronaut photograph how Interstate Route 8 and the All-American Canal cross the dune field. The 85-mile
(53-km) canal and its branches carry water westward, from the Colorado River (at 26,000 cubic feet per second) to homes and farms of California’s
Imperial Valley. It is the largest irrigation canal in the world. Runoff from land irrigated by the canal system drains into the Salton Sea. (Astronaut
