Hike Level: Easy – Moderate

On this field trip, we will visit the major faults in and around Joshua Tree National Park. These faults have been and will continue to be responsible for the land forms of JTNP. Our drive will take us north of Yucca Valley to the Landers Area where we will see offsets and uplifts that resulted from the 1992, 7.3 magnitude Landers earthquake. We will see roads, phone poles and fences that were offset as much as 8 feet. Next, we will follow the Pinto Mountain fault from Yucca Valley to Twentynine Palms. At the Twentynine Palms Visitor Center we will take a short walk along the Pinto Mountain Fault and discuss the fault activity that resulted in the Oasis of Mara. We will then travel to Key’s View where we will see the Blue Cut Fault and the San Andreas Fault. At Key’s View, we will be standing on the North American Plate looking across the San Andreas to the Pacific Plate. Our discussion will include the formation of the Little San Bernardino Mountains and the implications of the collision of the Pacific Plate with the North American Plate. If time permits we will visit fault features along the San Andreas in the Desert Hot Springs area.
