California's geology makes headlines when faults shift, volcanos puff steam, and waves crumble the coast. This popular book explores the recent rumblings and tremulous past of northern and central California. With expanded coverage, new maps and photographs, and the latest geologic interpretations, this nontechnical guide describes the region's rocks and landforms - from the sea stacks along the north coast to the tufa towers at Mono Lake, and from the flood basalts of the Modoc Plateau to the creeping fault of the Carrizo Plain.
