Grand Canyon, A Century of Change PDF Author: Robert H. Webb

ISBN: 0816547491
Category : History
Languages : en
Pages : 311

Book Description
Photographs made in Grand Canyon a century ago may provide us today with a sense of history; photographs made a century later from the same vantage points give us a more precise picture of change in this seemingly timeless place. Between 1889 and 1890, Robert Brewster Stanton made photographs every 1-2 miles through the river corridor for the purpose of planning a water-level railroad route and produced the largest collection of photographs of the Colorado River at one point in time. Robert Webb, a USGS hydrologist conducting research on debris flows in the Canyon, obtained the photographs and from 1989 to 1995 replicated all 445 of the views captured by Stanton, matching as closely as possible the original camera positions and lighting conditions. Grand Canyon, a Century of Change assembles the most dramatic of these paired photographs to demonstrate both the persistence of nature and the presence of humanity. Unexpected longevity of some plant species, effects of animal grazing, and expansion of cacti are all captured by the replicate photographs. More telling is evidence of the impact of Glen Canyon Dam: increased riparian vegetation, new marshes, aggraded debris fans, and eroded sand bars. In the accompanying text, Webb provides a thorough analysis of what each pair of photographs shows and places the project in its historical context. Complementing his narrative are six sidebar articles by authorities on Canyon natural history that further attest to a century of change. The level of detail obtained from the photographs represents one of the most extensive long-term monitoring efforts ever conducted in a national park; it is the most detailed documentation effort ever performed using repeat photography. Much more than simply a picture book, Grand Canyon, a Century of Change is an environmental history of the river corridor, a fascinating book that clearly shows the impact of human influence on Grand Canyon and warns us that its future is very much in our hands.

Grand Canyon For Sale

Grand Canyon For Sale PDF Author: Stephen Nash
Publisher: Univ of California Press
ISBN: 0520965248
Category : Science
Languages : en
Pages : 307

Book Description
Grand Canyon For Sale is a carefully researched investigation of the precarious future of America’s public lands: our national parks, forests, wildlife refuges, monuments, and wildernesses. Taking the Grand Canyon as his key example, and using on-the-ground reporting as well as scientific research, Stephen Nash shows how accelerating climate change will dislocate wildlife populations and vegetation across hundreds of thousands of square miles of the national landscape. In addition, a growing political movement, well financed and occasionally violent, is fighting to break up these federal lands and return them to state, local, and private control. That scheme would foreclose the future for many wild species, which are part of our irreplaceable natural heritage, and also would devastate our national parks, forests, and other public lands. To safeguard wildlife and their habitats, it is essential to consolidate protected areas and prioritize natural systems over mining, grazing, drilling, and logging. Grand Canyon For Sale provides an excellent overview of the physical and biological challenges facing public lands. The book also exposes and shows how to combat the political activity that threatens these places in the U.S. today.

Damming Grand Canyon

Pages : 312

Book Description
In 1923, America paid close attention, via special radio broadcasts, newspaper headlines, and cover stories in popular magazines, as a government party descended the Colorado to survey Grand Canyon. Fifty years after John Wesley Powell's journey, the canyon still had an aura of mystery and extreme danger. At one point, the party was thought lost in a flood. Something important besides adventure was going on. Led by Claude Birdseye and including colorful characters such as early river-runner Emery Kolb, popular writer Lewis Freeman, and hydraulic engineer Eugene La Rue, the expedition not only made the first accurate survey of the river gorge but sought to decide the canyon's fate. The primary goal was to determine the best places to dam the Grand. With Boulder Dam not yet built, the USGS, especially La Rue, contested with the Bureau of Reclamation over how best to develop the Colorado River. The survey party played a major role in what was known and thought about Grand Canyon. The authors weave a narrative from the party's firsthand accounts and frame it with a thorough history of water politics and development and the Colorado River. The recommended dams were not built, but the survey both provided base data that stood the test of time and helped define Grand Canyon in the popular imagination. Also by Robert Webb: Lee's Ferry

Saving Grand Canyon

Saving Grand Canyon PDF Author: Byron E Pearson
Publisher: University of Nevada Press
ISBN: 1948908328
Category : Nature
Languages : en
Pages : 332

Book Description
2020 Winner of the Southwest Book Awards 2020 Spur Awards Finalist Contemporary Nonfiction, Western Writers of America The Grand Canyon has been saved from dams three times in the last century. Unthinkable as it may seem today, many people promoted damming the Colorado River in the canyon during the early twentieth century as the most feasible solution to the water and power needs of the Pacific Southwest. These efforts reached their climax during the 1960s when the federal government tried to build two massive hydroelectric dams in the Grand Canyon. Although not located within the Grand Canyon National Park or Monument, they would have flooded lengthy, unprotected reaches of the canyon and along thirteen miles of the park boundary. Saving Grand Canyon tells the remarkable true story of the attempts to build dams in one of America’s most spectacular natural wonders. Based on twenty-five years of research, this fascinating ride through history chronicles a hundred years of Colorado River water development, demonstrates how the National Environmental Policy Act came to be, and challenges the myth that the Sierra Club saved the Grand Canyon. It also shows how the Sierra Club parlayed public perception as the canyon’s savior into the leadership of the modern environmental movement after the National Environmental Policy Act became law. The tale of the Sierra Club stopping the dams has become so entrenched—and so embellished—that many historians, popular writers, and filmmakers have ignored the documented historical record. This epic story puts the events from 1963–1968 into the broader context of Colorado River water development and debunks fifty years of Colorado River and Grand Canyon myths.

Landscape With Figures

Landscape With Figures PDF Author: Kent C. Ryden
Publisher: University of Iowa Press
ISBN: 1587294060
Category : Nature
Languages : en
Pages : 343

Book Description
Kent Ryden does not deny that the natural landscape of New England is shaped by many centuries of human manipulation, but he also takes the view that nature is everywhere, close to home as well as in more remote wilderness, in the city and in the countryside. InLandscape with Figures he dissolves the border between culture and nature to merge ideas about nature, experiences in nature, and material alterations of nature. Ryden takes his readers from the printed page directly to the field and back again-. He often bypasses books and goes to the trees from which they are made and the landscapes they evoke, then returns with a renewed appreciation for just what an interdisciplinary, historically informed approach can bring to our understanding of the natural world. By exploring McPhee's The Pine Barrens and Ehrlich's The Solace of Open Spaces, the coastal fiction of New England, surveying and Thoreau's The Maine Woods,Maine's abandoned Cumberland and Oxford Canal, and the natural bases for New England's historical identity, Ryden demonstrates again and again that nature and history are kaleidoscopically linked.
