Investigate the natural architecture and origin of Joshua Tree National Park’s landscape with Richard Hazlett, co-author of Joshua Tree National Park Geology. Starting in the classroom participants will be introduced to basic geologic principles including major rock groups, plate tectonics, mountain building, and the impact of weathering. Hazlett will discuss how these processes worked together to form the fantastic desert landscape of the park. The class will venture into the field on two excursions to observe and identify monzogranite, gneiss, aplite, and basalt rocks as well as inselbergs, tafoni, and pediment formations. For those new to geology or experienced geologists, Hazlett will make learning about this complex and unique landscape comprehensible and fun.
