The Geological Wonders of California’s Channel Islands

From volcanic sea caves to out-of-this-world sedimentary formations, the Channel Islands are a collection of geologically varied islands. Keri Dearborn will take us on a tour of the Channel Islands to see some of their unique geology, including San Nicolas Island which is a U.S. Navy Base and closed to the public.

The geology of the Channel Islands directly affects the plant and animal species that live there. This is called biogeology. We’ll look at the role geology has played in shaping the living species on the islands in the past and how it continues to do so today. We’ll look for fossils, archaeological sites, and evidence of islands on the move.  

Join Keri for an evening discovering the geologic wonders of the Channel Islands.

Emmy Silverman - Program Chair

Report on our Malibou Lake Event - Saturday, October 1, 2022

Yes, there is a Malibou Lake in the Santa Monica Mountains. And, it has been there for 100 years! Who knew? I didn’t but our club was invited to their centennial festival through the efforts of our member, Jon Meredith. Our booth consisted of two 10 x 10 canopies from 10 am to 6 pm and we talked to a constant flow of people. They were all interested in the free educational game, touch and feel area, spin-a-wheel with its goodies and many kinds of rock materials available for purchase as well as providing general information on the local rocks and fossils. Our members, Chris Ward and Maxine Dearborn gave a one hour PowerPoint talk on the history and geology of the Santa Monica Mountains and they had a very large audience. They also had a lot of questions about the subject because a lot of the people were from the surrounding local areas. Our club had a great time at this festival. It was a long day but we had a lot of help and the weather was just right. Members attending: Chris Ward, Bob Knox, Shellie Van Winkle, Bernadette Friedman, LaVere & Christine Schmidt, Jon Meredith, Jeff & Emmy Silverman and Bob & Maxine Dearborn.         Bob Dearborn-Education Outreach
