Heart of the Palm Springs Valley Situated in the geographic center of the Palm Springs Valley, Rancho Mirage’s location has played a major role in its development and success. Because it lies among the coves and alluvial fans of the Santa Rosa Mountains, Rancho Mirage proved to be an ideal getaway destination within easy driving distance from the Los Angeles area. The development of 18-hole golf courses with country club living and its proximity to Palm Springs helped Rancho Mirage blossom into the high-quality resort city it is today.
Rancho Mirage is geographically situated in the Colorado Desert, protected from most prevailing weather systems off of the Pacific Ocean by Mt. San Gorgonio (the highest peak in Southern California) and Mt. San Jacinto (the second-highest peak in Southern California). Average annual rainfall in Rancho Mirage is just 3.38 inches. The sun usually shines 350 of the year’s 365 days.
Many year-round and seasonal residents are refugees from colder areas of North America who have escaped the snow and freezing temperatures for this “oasis of gracious living.”
No discussion of the geography of the Palm Springs Valley would be complete without mentioning that the valley lies in a seismically active area, like all of California. There are small and moderate earthquakes from time to time in the area; however, none in modern history have done significant damage in Rancho Mirage. The San Andreas Fault runs through the Palm Springs Valley, parallel to Interstate 10 north of the freeway. The Palm Springs Valley is fairly stable on its bedrock foundation and doesn’t experience the soil liquefaction that is a common occurrence in Los Angeles area quakes. That being said, it is still recommended that every resident be prepared with an earthquake survival kit, a minimum three-day supply of food and potable water and have a plan of action for their families just in case.
