"Since Mountain Press started the Roadside Geology series forty years ago, southern Californians have been waiting for an RG of their own. During those four decades-which were puntuated by jarring earthquakes and landslides-geologists continued to unravel the complexity of the Golden State, where some of the most dramatic and diverse geology in the world erupts, colides. With dazzling color maps, diagrams, and photographs, Roadside Geology of Southern California takes advantage of this newfound knowledge, combining the latest science with accessible stories about the rocks and landscapes visible from winding two-lane byways as well as from the region's vast network of highways."
