Only recently has the astonishing modern theory of moving crustal plates enabled us to understand fully how the picturesque landscape of the San Francisco Bay Region and its surrounding areas has come into existence. In this book Howard tells the dramatic story, illustrated by clear, graphic sequential drawings: the continual remaking of the earths surface on a time scale so immense human minds can scarcely grasp it.

  • Roadside Geology of Oregon

    Until about 200 million years ago, the western margin of North America lay to the east, along the present Idaho border, and a broad coastal plain spread westward into Oregon. The rest of the state was ocean floor. Then the continent began moving slowly westward away from Europe and the floor of the Pacific Ocean began sliding beneath the western edge. That is what created Oregon, and this book tells how it happened.

  • Roadside Geology of Louisiana

    After Hurrican Katrina, the fanlike pile of sand, mud, and silt that formed near a breached levee was unique in the urban environment of New Orleans. Over the 7,500-year history of the modern Mississippi River delta, however, it was just another splay deposit. Author Darwin Spearing explains the geologic forces behind the formation of the delta, shedding light on the human struggle to control the powerful river that breaches its own levees and switches its own deltas. With sections on wetland loss and land subsidence, Roadside Geology of Louisiana is a must-read for understanding the vulnerability of the Mississippi River delta to floods and hurricanes.

    First published in 1995, Roadside Geology of Louisiana is back in print by popular demand, with several updated sections. The introduction presents an overview of Loiusiana's geological history, and 57 road guides discuss the landforms visible from a car window, including sand ridges, natural levees, oxbow lakes, and the Five Islands salt domes.
  • Geology of the Sierra Nevada, Revised Edition

    The Revised Edition of Mary Hill's popular book on the Geology of the Sierra Nevada published in April 2006. One of the California Natural History Guides, this volume makes a potentially dull subject come alive with clear descriptions of geomorphology, history, maps, drawings and color photographs.

    Mary Hill tells the story of the magnificent Sierra Nevada - the longest highest, and most spectacular mountain range in the contiguous United States. She takes us from the time before the land which would be California even existed., through the days of roaring volcanoes, violent earthquakes, and chilling ice sheets, to the more recent history of the Sierra's early explorers and the generations of adventuresome souls who followed. For thirty years, the first edition of Geology of the Sierra Nevada has been the definitive guide to the Sierra Nevada's geologic history for nature lovers, travelers, hikers, campers, and armchair explorers. This edition offers new chapters and sidebars and incorporates the concept of plate tectonics throughout the text.

    • Gives detailed information on where to view outstanding Sierra Nevada geology in some of the world's most beloved natural treasures and national parks, including Yosemite.
    • Superbly illustrated with 117 new color illustrations, 16 halftones, 39 line illustrations, and 12 maps.
    • Features and easy-to-use, interactive key for identifying rocks and a glossary of geologic terms.
  • The Geomorphic Evolution of the Yosemite Valley and Sierra Nevada Landscapes Solving the Riddles in the Rocks

    This book provides a new interpretation of the formation of Yosemite Valley and the entire Sierra Nevada range. Whereas previous interpretations said that the Sierra Nevada was a relatively young mountain range and that most of its deep valleys were carved by glaciers, this new view indicates that the Sierra is an old range and that most of the canyons and valleys owe their existence to mass wasting, or rockfall. Contrary to what most of us learned as the truth about the formation of the Sierra, Schaffer presents evidence that glaciers performed very little erosion.
    Jeff Schaffer is a naturalist and Yosemite climber who started exploring the Sierra Nevada in 1962. He has hiked more miles and explored more Sierran terrain than any other past or present naturalist or geologist, including John Muir and Fran?ois Matthes.
  • Roadside Geology of Texas

    The geologic panorama of Texas is as wide as the state is big, sweeping from volcanic mesas and thrusting mountains in the west to the red canyons of the Panhandle, along tropical sand barriers of the Gulf Coast, and across central limestone plateaus to the hard granitic terrain of central Texas. Learn about the rocks as you come to them - what they are, when they formed, what they mean, and how they fit into the big picture of the geology of Texas.
  • Roadside Geology of Wisconsin

    Robert H. Dott, Jr., and John W. Attig wrote Roadside Geology of Wisconsin to help residents and visitors alike "envision mastodons roaming in front of glaciers 12,000 years ago, feel storm waves pounding sea cliffs 500 million years ago, and hear volcanoes exploding 1,900 million years ago." With lively prose, detailed maps, black-and-white photographs, and shaded-relief images, the authors succeed in their goal: unraveling the 2,800 million years of geologic history recorded in Wisconsin's rocks.

    Introductory sections describe the geology of each region, and thirty-five road guides locate and interpret the rocks, sediments, and landforms visible from the state's highways, including the Great River Road in the Mississippi Valley. Roadside Geology of Wisconsin delves further into the geologic history of specific sites such as Apostle Islands National Lakeshore, the Wisconsin Dells, the geologically renowned Baraboo Hills, and more than twenty-five state parks. Features of and access points to the Ice Age National Scenic Trail are noted.
