Be mesmerized all over again by the incredible landscape we call home. In the book, Roadside Geology of Southern California, geologists/authors Arthur Sylvester and Elizabeth O'Black Gans explain complex geology and geologic history of features such as the San Andreas Fault, Joshua Tree National Park, the Channel Islands, and the Mojave Desert with detailed color maps, diagrams, and photographs. The authors also explain why the Santa Ynez Mountains (behind Santa Barbara) trend east-west, whereas most mountains in California and North American trend northwest. Roadside Geology of Southern California's 37 road guides traverse the region's major highways through mountains and deserts, as well as scenic, winding two-lane back roads. Within an eight-hour drive of any point in southern California, you may view results of almost every type of geologic process, from desert erosion to glaciation, giant prehistoric landslides to active earthquake faults. This is definitely a book you want to carry throughout your travels of our "Golden State" to help you best understand our region and appreciate it all the more. Book will be available for purchase and signing after the presentation at REI.
