Book Description
To discover the unworldly geologic novelties of the Gem State, all that is required is a good map, a sense of adventure, and Idaho Rocks!, a guide to 60 of the most compelling geologic sites in Idaho. The well-chosen destinations span the state's geologic history from the 2.6-billion-year-old gneiss in the Panhandle to 2,000-year-old lava at Craters of the Moon, and from gold and silver deposits hidden in Idaho's mountains to visible scars from recent earthquakes and landslides. With its beautiful photographs and informative figures and maps, this guidebook will get you up to speed on every aspect of Idaho's diverse geology. Northern and central Idaho's sparkling rivers flow past algal mounds in 1.4-billion-year-old limy sediments, sandy beaches eroded from crystalline granite, and exotic rocks of ancient volcanic islands. Southern Idaho has been shaped by calderas of the Yellowstone hot spot, along with active faults of the Basin and Range, and one monumental flood that carried boulders the size of cars. Rock hounds can search for star garnets along Emerald Creek, zeolite crystals in basalt cavities, and eye-shaped feldspar in ancient gneiss. Fossil enthusiasts can discover leaf imprints at Clarkia Fossil Beds, learn about Pliocene horses at Hagerman Fossil Beds, and contemplate the bizarrely whorled teeth of the buzz saw shark who prowled the sea 290 million years ago when Idaho's phosphate deposits were accumulating.

Book Description
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.

Book Description
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.

Book Description
How many states claim quartz as their official state gem? This guidebook answers this question and more as it explores the treasures that are designated official state gems and minerals. Over 150 photographs showcase these marvels, from the Star Blue quartz of Alabama to the jade nephrite of Wyoming. Each state entry is presented with details about the state gem and mineral, with pictures of each, and a map of the state showing where the gem or mineral can be found. Some states do not yet have designated gems or minerals, and suggestions and guidance are provided so that the reader can lead the way in getting one designated. Museums and parks with minerals are listed in the appendix so readers can go see specimens in person. Encyclopedic yet easy to read, this book is great for mineral and gem enthusiasts and future geologists of all ages.
