Geology Hike: Ash Wash
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.
