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

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.

The Late Cenozoic history of the western Grand Canyon is one of profound and rapid transformation. The constantly changing morphology and dynamics of the canyon during this period have been recorded in spectacular geologic features, such as frozen lava cascades and lava dams, as well as volcanic cones, necks, and dikes. All of these unique features, which make the western part of the Grand Canyon strikingly different from other parts, resulted from the interaction of basaltic lava flows and vigorous erosion by the Colorado River. The volcanic phenomena in the Grand Canyon were created by eruptions of basaltic lava in the southernmost part of the Uinkaret volcanic field. Some lava flows were extruded on the Uinkaret Plateau and cascaded over the outer rim of the Grand Canyon into Toroweap Valley and Whitmore Wash, while others were extruded within the Grand Canyon itself and partly covered the Esplanade Platform. The remaining flows cascaded over the rim of the canyon's inner gorge. Red molten rock cascading into the canyon and forming lava dams must have presented a spectacular scene, the likes of which have never been viewed by human beings. Even more spectacular is how quickly these lava dams formed - from small single-flow dams that were created in only a few days, to complex, multiple-flow dams that took several thousand years. The dams were then destroyed when the water impounded behind them ultimately overflowed. Although their construction and destruction occurred in a geologic instant, these events were the most significant in the late Cenozoic history of the Grand Canyon. Because of the largely inaccessible nature of the western part of the canyon, the author and his field assistants researching this area had to be creative in their data-gathering techniques. For example, they made photo mosaics of the entire canyon wall using a hand-held aerial camera; these mosaics served as cross sections on which all geological data were plotted. In addition, to photograph features hidden from view at river level, they utilized light aircraft and helicopters. Finally, a professional mountain climber collected samples from various units exposed high on vertical cliffs. Memoir 183 is a compilation of this field work, which took more than two decades to complete. It contains numerous maps, photographs, and cross sections of frozen lava cascades and the remnants of a sequence of 13 major lava dams that once formed huge barriers to the Colorado River. The volume also discusses the history of lakes that formed behind these lava dams and the associated sedimentary deposits that once partly filled the Grand Canyon. The results of this study provide new insights into the rates at which the Colorado River is able to downcut its channel, as well as the major factors that controlled erosion of the Grand Canyon.

"Focusing on the saddening, maddening example of Glen Canyon, Jared Farmer traces the history of exploration and development in the Four Corners region, discusses the role of tourism in changing the face of the West, and shows how the "invention" of Lake Powell has served multiple needs. He also seeks to identify the point at which change becomes loss: How do people deal with losing places they love? How are we to remember or restore lost places?"--BOOK JACKET.

The Grand Canyon Monitoring and Research Center began long-term planning at its inception and, in May 1997, produced a Long-Term Monitoring and Research Strategic Plan that was adopted by stakeholder groups (the Adaptive Management Work Group and the Technical Work Group) later that year. The Center then requested the National Research Council's (NRC) Water Science and Technology Board to evaluate this plan.

Federal management of water is undergoing a change that involves a drastic reduction in the number of new water projects and an increase in emphasis on the quality of water management. This book summarizes and analyzes environmental research conducted in the lower Colorado River below the Glen Canyon Dam under the leadership of the Bureau of Reclamation. It reviews alternative dam operations to mitigate impacts in the lower Colorado riverine environment and the strengths and weaknesses of large federal agencies dealing with broad environmental issues and hydropower production. While many problems remain to be solved, the Bureau of Reclamation through the Glen Canyon area. The lessons of GCES are transferable to other locations and could be the basis for a new era in the management of western waters.
