Allow yourself to be taken back into deep geologic time when strange creatures roamed the Earth and Western North America looked completely unlike the modern landscape. Volcanic islands stretched from Mexico to Alaska, most of the Pacific Rim didn’t exist yet, at least not as widespread dry land; terranes drifted from across the Pacific to dock on Western Americas’ shores creating mountains and more volcanic activity. Landscapes were transposed north or south by thousands of kilometers along huge fault systems. Follow these events through paleogeographic maps that look like satellite views of ancient Earth. Accompanying text takes the reader into the science behind these maps and the geologic history that they portray. The maps and text unfold the complex geologic history of the region as never seen before. Winner of the 2021 John D. Haun Landmark Publication Award, AAPG-Rocky Mountain Section

The Geology, Ecology, and Human History of the San Luis Valley explores the rich landscapes and diverse social histories of the San Luis Valley, an impressive mountain valley spanning over 9,000 square miles that crosses the border of south-central Colorado and north-central New Mexico and includes many cultural traditions. Twenty-six expert scholars and educators—including geologists, geographers, biologists, ecologists, linguists, historians, sociologists, and consultants—uncover the natural and cultural history of the region, which serves as home to the Sangre de Cristo Mountains, the San Juan Mountains, Great Sand Dunes National Park and Preserve, and the Rio Grande headwaters. The first section, “The Geology and Ecology of the San Luis Valley,” surveys the geomorphology, hydrology, animal and plant life, conservation, management, and mining of the valley’s varied terrain. The second section, “Human History of the San Luis Valley,” recounts the valley’s human visitation and settlement, from early indigenous life to Spanish exploration to Hispanic and Japanese settlements. This section introduces readers to the region’s wide range of religious identities—Catholic, Latter-day Saint, Buddhist, Jehovah’s Witness, Amish, and Mennonite—and diverse linguistic traditions, including Spanish, English, Dutch, Danish, Japanese, and Mayan. The final section, “Travel Itineraries,” addresses recreation, specifically fly-fishing and rock climbing. The book provides a comprehensive overview of the endemic flora and fauna, human history of indigenous lifeways, and diverse settlement patterns that have shaped the region. The Geology, Ecology, and Human History of the San Luis Valley will appeal to students and scholars of geology, ecology, environmental history, and cultural history, as well as residents and tourists seeking to know more about this fascinating and integral part of Colorado and New Mexico.

"Rough-Hewn Land tells the geologic story of the American West--the story of its rocks, rivers, mountains, earthquakes, and mineral wealth, including gold. It tells it by taking you on a 1000-mile-long field trip across the rough side of the continent from the California coast to the Rocky Mountains. This book puts you on the outcrop, geologic hammer in hand, to explore the evidence for how the spectacular, rough-hewn lands of the West came to be. When North America broke free from Eurasia and Africa some 200 million years ago, it triggered a cascade of violent geologic events that shaped the West we see today. As the west-moving continent crunched across the seabed of the ancient Pacific, islands and assorted pieces of ocean floor collected against its prow to build California--and plant gold there too. Meanwhile, mountains squeezed upward from California to Colorado, and vast quantities of molten rock seeded the crust with precious metals while spewing volcanic fire across the land. Later, the land stretched like an accordion to form the washboard-like Basin and Range province and Great Basin within it, while California began to crackle along the San Andreas fault. Throughout the West today, a near-constant drumroll of earthquakes testifies to a world still reshaping itself in response to the ceaseless movements of the Earth's tectonic plates. Rough-Hewn Land weaves these stories into the human history of the West. As we follow the adventures of John C. Frémont, Mark Twain, the Donner party, and other historic characters, we see how geologic forces have shaped human experience, just as they direct the fate of the West today"--

The geologic history of the Pacific Northwest is as unique as the region itself. Completely reorganized and revised, the Third Edition of Geology of the Pacific Northwest brings the area’s volcanism, earthquakes, tsunamis, and geologic environmental issues into sharp focus. William and Elizabeth Orr provide a singular perspective and explore the Pacific Northwest writ large, including Southeast Alaska, British Columbia, Washington, Oregon, Idaho, and northern California. Descriptive and detailed photographs of the formations and terranes of each subregion are included, along with color plates that illuminate and expose the fundamental processes that shaped Pacific Northwest geology. The text reveals the geological origins, geographic features, phenomena, and natural resources of areas throughout the region. As urban development continues to expand in the tectonically active Pacific Northwest, environmental concerns and geologic hazards will grow more and more important. The authors’ central theme that continental plate tectonics are the fundamental processes of Northwest geologic history leads to deeper understanding of the region’s geology and new insights in volcanic eruption prediction, disaster preparedness, and the environmental effects of mining.

"Dr. John M. Dennison spent his career studying the Appalachians, teaching and mentoring his students and professional colleagues, publishing papers, leading field trips, and presenting ideas at regional, national and international conferences. This volume is a collection of papers contributed by former students and colleagues to honor his memory. Learn about stratigraphy and paleontology ranging in age from Ordovician to Mississippian in Kentucky, New York, Tennessee, Virginia, and West Virginia; Devonian airfall tephras throughout the eastern United States; a Devonian lonestone; a Middle Eocene bentonite in North Carolina and its relationship to a volcanic swarm in western Virginia; and a 3D model of a ductile duplex in northwestern Georgia. The stratigraphic and geologic diversity of the papers reflect Dennison's many interests and relationships with a large group of geoscientists"--
