When the first edition of Roadside Geology of Oregon was published in 1978, it was revolutionary�the first book in a series designed to educate, inspire, and wow nongeologists. Back then, the implications of plate tectonic theory were only beginning to shape geologic research and discussion. Geologists hadn�t yet learned that Oregon�s Klamath and Blue Mountains were pieces of far-traveled island arcs and ocean basins that had been piled against the growing North American continent. Steaming volcanoes, ghost forests, recent landslides, and towns heated with geothermal energy attest to Oregon�s still-prominent position at the edge of an active tectonic plate. Author, photographer, and geologist Marli Miller has written a completely new second edition based on the most up-to-date understanding of Oregon�s geology. Spectacular photographs showcase the state�s splendor while also helping readers understand geologic processes at work. Roadside Geology of Oregon, Second Edition, is a must-have for every Oregon resident, student, and rockhound.

Since the first edition of Roadside Geology of Washington appeared on the book shelves in 1984, several generations of geologists have studied the wild assortment of rocks in the Evergreen State, from 45-million-year-old sandstone exposed in sea cliffs at Cape Flattery to 1.4-billion-year-old sandstone near Spokane. In between are the rugged granitic and metamorphic peaks of the North Cascades, the volcanic flows of Mt. Rainier and the other active volcanoes of the Cascade magmatic arc, and the 2-mile-thick flood basalts of the Columbia Basin.

"To discover astonishing rocks and landforms in the Beaver State, all that is required is a good map, a sense of adventure, and Oregon Rocks, a guide to 60 of the most compelling geologic sites in the state. The well-chosen destinations span the state's geologic history from the Triassic marble at Oregon Caves to the 240-year-old lava dome on Mt. Hood. With more active volcanoes than any other state in the Lower Forty-Eight, Oregon boasts towering behemoths, steaming fumaroles, and eroding cinder cones. Geologist Marli Miller will guide you through the ash and lava from recent eruptions to find evidence of older ones, including a supervolcano possibly produced by the Yellowstone hot spot before it tracked east, and lava that flowed all the way to the coast from eruptions near the Oregon-Idaho border. Although residents of eastern and western Oregon may not admit they have anything in common, the barnacled sea stacks near Cannon Beach and Tillamook are composed of the exact same rock as stacked lava flows on the Columbia Plateau. With beautiful photographs and informative figures and maps, this guidebook will unite Oregonians in their pursuit of outdoor exploration, be it rock hounding, peak bagging, beachcombing, or contemplating their place in the long history of the Earth"--

The book begins with an introductory chapter that briefly reviews California's geology followed by a series of road guides with the local particulars. The authors tell you what the rocks re and what they mean. Useful graphics and charts supplement the t

California's geology makes headlines when faults shift, volcanoes puff steam, and coastal bluffs fall into the sea. This book explores the state's recent rumblings and tremulous past with the aid of full color illustrations. Photographs showcase multihued rock, from red chert and green serpentinite to blue schist and gray granite. The geologic information, particularly for the Klamath Mountains, Modoc Plateau, and northern Sierra Nevada, has been updated to reflect new geologic understanding of these complex areas. Features detailed, easy to read color geologic road maps based on the 2010 Geologic Map of California.

The geologic history of the Pacific Northwest is as unique as the region itself. Created via tectonic plate movements and accretionary events, the original terranes were subsequently covered by sedimentary layers, ash, lavas, and glacial debris. These processes, begun millions of years ago, continue to affect the area, as seen in the eruption of Mount St. Helens and catastrophic Japanese tsunamis created by earthquakes in the Pacific Northwest. Understanding of the regions geology has led to new insight in volcanic eruption prediction, disaster preparedness, the environmental effects of mining, and urban development as it relates to geologic hazards. The Orrs detailed and informative writing style appeals to those with geologic training as well as beginners with an interest in the region. Each chapter covers a specific subregion, allowing for maximum flexibility both in the classroom and for the casual reader. The authors central theme that continental plate tectonics are the fundamental processes of Northwest geologic history permeates throughout the book.
