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.

Arches National Park. Bryce Canyon. Zion. When one thinks of Utah, it's rocks and iconic landforms—preserved in a nearly endless list of national parks and monuments—come immediately to mind. Perhaps more so than any other state, Utah is built for geologic exploration, and geologists/authors Felicie Williams, Lucy Chronic, and Halka Chronic are its expert tour guides.The Beehive State is splitting at the seams with wondrous geological contrast. Utah's high mountains, showcasing the results of what happens as the Earth bends, folds, and breaks itself apart, run like a backbone down the center of the state. To the east, the Colorado Plateau's flat-lying sedimentary rock is wondrously exposed in canyons, arches, and breaks. To the west is the immense Great Basin, a region characterized by rank upon rank of long, narrow, gaunt mountain ranges alternating with desert basins that are among the flattest surfaces on Earth.Roadside Geology of Utah's 65 road guides traverse the state's major thoroughfares as well as its dusty, sleepy, winding two-lane highways. With fresh prose and more than 300 color photos, maps, and figures to boot, you too will become expert at reading Utah's rocks.

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.

British Columbia was built by some 500 million years of geologic discord along the western margin of the North American tectonic plate. That turmoil continues today, as the Juan de Fuca tectonic plate inches beneath Vancouver Island, triggering earthquakes and generating the magma that feeds the volcanoes of the Cascades. This book explains the province's geologic history in simple terms, covering southern British Columbia from the northern tip of Vancouver Island to the BC-Alberta border. Thirty-one descriptive road guides, complete with maps, photographs and diagrams, help you locate and interpret the rocks and landforms visible from the provinces highways and ferry routes. Discover a lava flow that chilled beneath ice, learn how Ripple Rock claimed 24 ships before engineers finally blew it up, and drive across a slow-moving earthflow that has played havoc with roads since the gold-rush days. The book a sense of the geology's importance to everyone who lives in and passes through the province.
