4WD Field Trip: Ancient Lake Cahuilla

ABDNHA Parking Lot 652 Palm Canyon Drive, Borrego Springs

Special Earth Science Series!

Leader: John Peterson, Hydrologist and Geologist

Approximately 12,000 years ago, the Colorado River altered its course, forming a massive prehistoric lake known as Lake Cahuilla, which is now the Salton Sea.   The lake served as a vital resource for the Cahuilla, Kumeyaay, and Cocopah peoples. Over the centuries, the lake filled and dried up many times. It last filled between 1731 and 1733. Hydrologist John Peterson will lead a half-day field trip to the Salton Sea, where participants can explore the ancient lake's remnants, including visible "bathtub rings" and fishing traps. Meet at ABDNHA at 8:15 am. General Public: $18, Members: $12, Volunteers: $10. Register online or at the Nature Center, 760-767-3098.
