  • Geology Hike: Ash Wash

    ABDNHA Parking Lot 652 Palm Canyon Drive, Borrego Springs, CA, United States

    Speaker: Don Barrie, Geoscience Educator, ABDNHA Board Member

    Join Don Barrie for this moderate 5-mile loop hike to Ash Wash, a tributary of Coyote Canyon. Our destination will be the Bishop Tuff—an ash layer deposited around 760,000 years ago when an enormous volcanic eruption created the Long Valley Caldera in the eastern Sierras. During this eruption, huge volumes of ash were blown into the atmosphere, resulting in widespread deposition as far away as the Midwest. At the entrance to Ash Wash, we’ll examine the Coyote Creek Fault—the western branch of the San Jacinto Fault Zone. Max 23 people (carpooling is encouraged). Bring lunch and water. 4WD vehicle recommended. Hiking poles, if you have them. Meet at ABDNHA. No charge, but registration is required at the Nature Center, 760-767-3098.

  • 4WD Field Trip: Ancient Lake Cahuilla

    ABDNHA Parking Lot 652 Palm Canyon Drive, Borrego Springs, CA, United States

    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.
