Big Morongo Canyon Preserve contains some of the oldest rocks in California which are dated to almost two billion years. It's located in San Bernardino and Riverside Counties in Southern California where you will find two distinct ecosystems.


High Desert and Low Desert ecosystems are defined by differences in elevation, climate, native vegetation, and animal life. The Preserve elevations which are considered High Desert, range from 1,700 feet to over 4,000 feet. This desert oasis on the canyon floor is a fertile wildlife sanctuary for bighorn sheep, deer, and mountain lions to rare and usual birds, butterflies, and reptiles.
