Los Angeles is completely destroyed, and the collapse of dams throughout California causes the San Joaquin Valley to become an inland sea. The second half of this novel focuses on an enclave of civilization in the fictional "Silver Valley", located slightly east or northeast of Springville, and just north of the Middle Fork of the Tule River. Several key scenes in Alfred Hitchcock's Saboteur take place at a ranch in Springville.
