Colorado Desert
Colorado Desert: Colorado is derived from the Spanish word for “colored red”,
The Colorado Desert is a subregion of the larger Sonoran Desert, covering about 7 million acres. The desert occupies Imperial County, parts of San Diego and Riverside counties, and a small part of San Bernardino County in California, as well as the northern part of Mexicali Municipality in Baja California, Mexico.

Most of the Colorado Desert lies at a relatively low elevation, below 1,000 ft , with the lowest point of the desert floor at 275 ft below sea level, at the Salton Sea, not very far from Borego Springs visitor center. That is a lot of desert and as stated in previous post San Diegos portion is 640,000 acres.
