Along with our day and half-day classes and programs, ABF also offers extended, multi-day programs that will take participants much deeper into the subjects being discussed. These trips range in length from two days to two weeks.
Join earth scientist Paul Remeika on a seven-day, two-wheel-drive geologic trek across the uneasy crust of California’s easternmost frontier. This special Desert Hostel field trip highlights the natural wonders between the subsiding Owen’s Valley and the uplifted tilt-block of the Sierra Nevada mountain range. We will follow immense earthquake fault escarpments through the boulder-strewn fantasyland of the Alabama Hills, to the Volcanic Tableland north of Bishop, California at the foot of California’s spectacular Sierra Nevada mountain range. Witness the volatile volcanic terrain inside of the Long Valley Caldera and its Resurgent Dome from atop Mammoth Mountain and Obsidian Dome. This active Quaternary volcanic center was created by a catastrophic eruption some 750,000 years ago, that sent tremendous ash clouds into the atmosphere, blanketing much of the western United States including the Anza-Borrego Desert.
