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. General Public: $18, Members: $12, Volunteers: $10. Register online or at the Nature Center, 760-767-3098.
