The introductory section of the book has an overview of the geology of the Pacific Northwest to give the necessary background and context for understanding the origin and evolution of large-scale landscapes. The Theory of Plate Tectonics revolutionized every aspect of earth science when it was formulated in the 1960s. This great unifying theory gave us a conceptual understanding of the origin and evolution of the major features of the continents and ocean basins. Throughout most of geological time archipelagos and microcontinents (the building blocks) have accreted to continents and continents have broken apart by rifting. Few continental margins of the Earth have been as affected by these processes as the American West. The Introduction also includes a timeline for the important events through geologic time and an overview of the common rocks and minerals of Idaho. Part two features geologic provinces and major rock types occurring in Idaho, and in many cases, extending over other States in the American West. Geologically significant landforms and features are scattered throughout Idaho and adjacent states. Many of these features are scientifically significant because they are among the best examples of their kind regionally, nationally, and in a few cases, globally. Part three describes water resources and features formed by water. Part four covers lode, placer, and gemstone deposits, using many Idaho examples.Idaho has outstanding examples of almost every type of landform, scientifically significant feature, rock type and mineral deposit. The oldest rocks are more than 2500 million years old and contain a record of many the events that transpired during that vast span of geologic time, including accretion of a significant portion of the Pacific Northwest terranes. During the last 20,000 years, Idaho has experienced major earthquakes, catastrophic floods, huge glacial ice sheets and volcanic eruptions. By visiting these diverse geologic environments, it is possible to develop a broad background in field geology applicable to understanding geology almost anyplace on earth.

Geology professor Willsey aims to inspire more Idahoans and visitors to take an interest in one of the most compelling and fascinating regions of the earth. He aims to bridge the gap between geologists and the interested public by passing along a collection of fascinating stories told by southern Idaho's rocks and landscapes. Southern Idaho's geologic history spans about 2.5 billion years--more than half that of the Earth. Chapters represent a sampling of the unique geologic features that formed during this immense amount of time. Willsey selects accessible locations that are exceptional in terms of either location or geologic history. --Publisher.

In this book, the first written on the geology of Hells Canyon, a world-class scientist tells the story of the deepest gorge on the North American continent. Born as islands in the Pacific Ocean, the rocks in Hells Canyon moved slowly northward with the North American continent after it broke loose from the Pangea supercontinent. Finally, the islands collided with the North American continent and were zippered to it. Bathed again by the sea, deeply eroded, and subsequently covered beneath a mile of lava flows, the entire area was lifted by, and along, large faults. In addition to telling the geologic history of the canyon, the book includes a mile-by-mile guide to the major features of Hells Canyon. A glossary and an annotated bibliography also complement the author's narrative along with his personal reminiscences and more than 100 photographs, many in full color.
