Eastern California–a geologically dramatic region with the ever-present risk of volcanic eruptions, earthquakes, flash floods, and sand storms–boasts spectacular and easily viewed rocks and landforms. Authors Allen Glazner and Art Sylvester build on coauthor Bob Sharp’s insights to produce this full-color illustrated guide to 33 amazing geologic sites in Death Valley and the surrounding region. Learn how stones slide across the Racetrack playa, find the rocks missing from Dantes View, and visit the rim of the Long Valley caldera, an enormous depression left by a supervolcano eruption far larger than any that has occurred since the dawn of civilization.
