The Salton Sink is a geographic sink in the Coachella Valley and Imperial Valley)[citation needed] of Southeastern California near the Arizona border. It is in the Colorado Desert subregion of the Sonoran Desert ecoregion.[citation needed]
Geology
The Salton Sink,[specify] in the Salton basin,[citation needed] is a pull apart basin resulting from the combined actions of the San Andreas Fault and the East Pacific Rise which are co-terminous with each other in this area.[citation needed]
History
In California in the autumn of 1904, the river's[specify] waters escaped into a diversion canal from the Colorado River a few miles below Yuma, Arizona, creating the New River and Alamo River, and over two years re-forming the Salton Sea. The river re-created the Salton Sea,[citation needed] an area that it had frequently inundated before. Previously in 1884 and 1891 the river semi-abandoned its regular course through Mexico to the Sea of Cortez, and flowed into the Salton Sink. However, it was effectively dammed in the early part of 1907 and it returned to its normal course, although from which there was still much leakage to the Salton Sea. In July 1907 a permanent dam was finished to keep the Colorado's normal course through the Colorado and Yuma Deserts towards the Colorado River Delta and the Gulf of California (Sea of Cortez).[citation needed]
