Salton Sea, Gran Desierto de Altar and Mouth of Colorado River, USA and Mexico33.2N 115.7W
Visible in the upper left quadrant of this image is the Salton Sea, a huge but shallow, saline, endorheic rift lake located directly on the San Andreas Fault, predominantly in California’s Imperial and Coachella Valleys.
The lake occupies the lowest elevations of the Salton Sink in the Colorado Desert of Imperial and Riverside counties in Southern California. The sea is fed by the New, Whitewater, and Alamo rivers, as well as agricultural runoff drainage systems and creeks. Visible south of the sea is irrigated land in southern California and Mexico.
In the lower right quadrant, sediments from the Colorado River can be observed spilling into the Gulf of California or Sea of Cortez. The Gran Desierto de Altar, one of the major portions of the Sonoran Desert of Mexico, can also be seen extending across much of the northern border of the Gulf of California. It reaches more than 100 kilometers east to west, and over 50 km north to south, and constitutes the largest continuous wilderness area within the Sonoran Desert, as well as including the only active erg dune region in North America.
