Twenty-five years after writing the groundbreaking Roadside Geology of Northern California, David Alt and Donald W. Hyndman have written an entirely new book--with expanded coverage, new photos and maps, and the latest interpretations of California's turbulent rocks. Geologic road guides include tours of Lake Tahoe, Yosemite National Park, Lassen Volcanic National Park, Lava Beds National Monument, Kings Canyon National Park, Point Reyes National Seashore, and the San Francisco Bay area. Learn about earthquake prediction, gold mining, pillow basalts, cinder cones, and more with this book as your guide.
Description: Eastern California boasts the greatest dryland relief in the contiguous United States, between 14,499-foot Mt. Whitney in the Sierra Nevada and minus-282-foot Badwater Basin in Death Valley. That relief offers a rich variety of environments--and spectacular geology. Through driving and walking tours, Geology Underfoot in Death Valley and Owens Valley provides an on-the-ground look at the processes sculpting the terrain in this land of extremes.
Illustrated with photographs, maps, and diagrams, each geological vignette weaves the tale of a particular scene, feature, or relationship in the landscape. Some sketches ponder questions that have puzzled geologists: what formed the turtlebacks in the Black Mountains and how do stones mysteriously slide on desolate Racetrack Playa? Others spotlight the role of volcanoes and earthquakes as landscape artists: the superb lava columns of Devil's Postpile, the massive steam explosion at Ubehebe Crater, and fault scarps that shape a golf course's greens. Still others focus on less obvious but equally powerful geologic processes: boulders shattered by salt crystals and rocks blasted by windblown sand. Together, these snapshots introduce readers to eastern California's rich, dynamic geology.
Standing before any of southern Utah?s enigmatic landforms, it?s clear there?s a story here. What carved the goblins in Goblin Valley, the domes at Capitol Reef, the towering sandstone walls of Zion Canyon, and Bryce?s hoodoo fairyland, not to mention all those arches and natural bridges? Geology Underfoot in Southern Utah explores the stories behind 33 handpicked sites, some world-famous, others off the beaten path. Marvel at tales of ancient eruptions, deserts, seas, and swamps; the movements of massive rock units over eons; and the rock?s interactions with the life above it, including humankind. Along the way, visit dinosaur trackways, old mines, rock glaciers, oysters in the desert, and more.
