  • Sunset at Mojave Desert in Twentynine Palms, CA

Stretch your legs and enjoy the spectacular scenery of the Cottonwood Mountains with Ted Reeves, in this all-day field class. Reeves will discuss the geologic history of Joshua Tree National Park, and the rocks and plants of the Cottonwood Mountains. We will also discuss some human history of the Cottonwood Spring area during the late 1800s. Participants will walk six miles through the rolling hills of the Colorado Desert to see mills, mines, and more. Along the trail, Reeves will share the adaptations of plants and animals to the desert environment. A portion of the walk will follow a prominent freight road built in the 1880s. Attendees will learn what is known about the road’s creation and use. Don’t miss the opportunity to learn how geology is connected to cultural history at Cottonwood Spring!

California is a state defined by plate tectonics, motion, continental drift, and subduction zones. Join geologist Ted Reeves as he explains the origin and effects of the San Andres Fault system. Reeves will unfold the geologic story of the Indio Hills, the Mecca Hills and SaltonTrough in this all-day field class. Participants will meet at the Coachella Valley Preserve and walk a short distance to see fault features. We will then travel to Box Canyon and Painted Canyon and observe spectacular faults and folds where the Pacific plate is forcing up the Mecca Hills. Reeves will illuminate fault-related features in the field with special emphasis on physical deformations of the landscape. Don’t miss this unique opportunity to explore the San Andreas fault zone and the palm oases!

Investigate the natural architecture and origin of Joshua Tree National Park’s landscape with Tor Lacy, geology professor, Cerritos college. 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 and erosion. Tor 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, veins, and basaltic rocks as well as inselbergs, alluvial fans, and pediments. For those new to geology or experienced geologists, Tor will make learning about the complex and unique landscape of Joshua Tree National Park comprehensible and fun.

Volcanoes of Southern California? We are famous for faults, and earthquakes, and maybe for other geologic phenomena, but not volcanoes. Still, when we look to our landscape we find evidence of volcanic activity, some of it quite recent. In this class we will learn basic concepts of geology and explore Amboy Volcano and the surrounding lava fields to understand why they formed, and if they could become active again! Designated a National Natural Landmark in 1973, Amboy Crater was recognized for its visual and geological significance. There are a number of dormant volcanoes in the Mojave desert, and Amboy crater is a perfect example of a cinder volcanic cone very similar to the volcanoes throughout the region. Join Professor Alessandro Grippo on this all-day field trip.
