Coachella Valley

The Coachella Valley is a desert valley in Southern California which extends for approximately 45mi in Riverside County southeast from the San Bernardino Mountains to the northern shore of the Salton Sea. It is the northernmost extent of the vast trough which includes the Salton Sea, the Imperial Valley and the Gulf of California. It is approximately 15mi wide along most of its length, bounded on the west by the San Jacinto Mountains and the Santa Rosa Mountains and on the north and east by the Little San Bernardino Mountains. The San Andreas Fault crosses the valley from the Chocolate Mountains in the southeast corner and along the centerline of the Little San Bernardinos. The fault is easily visible along its northern length as a strip of greenery against an otherwise bare mountain.The Chocolate Mountains are home to a United States Navy live gunnery range and are mostly off-limits to the public. In comparison to the "Inland Empire (IE)" (Riverside-San Bernardino area and the California desert), some people refer to the IE's sub-region Coachella Valley as the "Desert Empire" to differentiate it from the neighboring Imperial Valley. Geographers and geologists sometimes call the area, along with the Imperial Valley to the south, the "Cahuilla Basin" or the "Salton Trough".
