Book Description
Geomorphological Fieldwork addresses a topic that always remains popular within the geosciences and environmental science. More specifically, the volume conveys a growing legacy of field-based learning for young geomorphologists that can be used as a student book for field-based university courses and postgraduate research requiring fieldwork or field schools. The editors have much experience of field-based learning within geomorphology and extend this to physical geography. The topics covered are relevant to basic geomorphology as well as applied approaches in environmental and cultural geomorphology. The book integrates a physical-human approach to geography, but focuses on physical geography and geomorphology from an integrated field-based geoscience perspective. - Addresses fluvial and karst landscapes in depth - Focuses on field-based learning as well as educational geomorphology - Conveys experiential knowledge in international contexts

Book Description
Established by Sandia Corporation in 1957, Tonopah Test Range (TTR) in Nevada provided an isolated place for the Atomic Energy Commission and successor agencies to test ballistic characteristics and non-nuclear components of atomic bombs. Also known as Area 52, the vast outdoor laboratory served this purpose throughout the Cold War arms race and continues to play a vital role in the stewardship and maintenance of the United States' nuclear arsenal. The range has been used for training exercises, testing rockets, development of electronic warfare systems and unmanned aerial vehicles, and nuclear safety experiments. During the late 1970s, the Air Force constructed an airfield for a clandestine squadron of captured Russian fighter planes that were used for tactical evaluations and to provide realistic air combat training for thousands of US airmen. The TTR airfield also served as the first operational base for the F-117A stealth fighter, an airplane designed to be virtually invisible to detection by radar. Now operated primarily by Sandia National Laboratories for the Department of Energy and, in part, by the Air Force Materiel Command, TTR remains a valuable national asset with unparalleled capabilities.

Book Description
"Emmet Gowin likes to ask a provocative question: "Which country on earth has had the largest number of nuclear bombs detonated within its borders?" The answer is the United States. Covering approximately 680 square miles, the Nevada National Security Site, formerly known as the Nevada Test Site, was the primary testing location of American nuclear devices from 1951 to 1992; 1,021 announced nuclear tests occurred there, 921 of which were underground. The site, which is closed to the public, including its airspace, contains 28 areas, 1,100 buildings, 400 miles of paved roads, 300 miles of unpaved roads, 10 heliports, and two airstrips. Its surface is covered with subsidence craters from testing, and in places looks like the moon. In 1996, Gowin received permission to document the landscape by air, after over a decade of working to secure access. These aerial views of environmental devastation--made quietly majestic but no less potent in the hands of a master photographer--unveil environmental travesties on a grand scale. While groups of images from the Nevada Test Site series have been published previously, this book will produce the largest number yet, and three quarters of the pictures will not have been published at all. Gowin is the only photographer to have been granted access to this site, which is now permanently closed, post-9/11. Other than images made by the government for geographic purposes, no other images of this landscape exist. The book will feature a preface by photographer Robert Adams (America, b. 1937), whose photographic and written work is concerned with landscape, urbanization, and activism. It will also feature an afterword by Gowin on how he made the images, and their significance to him today."--Provided by publisher.

Book Description
Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 186. The Nevada Test Site (NTS) was established on December 18, 1950, to provide an area for continental testing of nuclear devices. In January of 1951, testing began with an airdrop into Frenchman Flat in conjunction with Operation Ranger. In addition to airdrops, above ground testing included surface detonations, tower shots, and balloon suspensions. Underground testing began in 1957, and since 1963, all events have been buried in large-diameter drill holes or tunnels. Geologists from the U.S. Geological Survey (USGS) mapped much of the NTS region between 1960 and 1965. These maps formed the basis for subsequent studies by Lawrence Livermore National Laboratory, Los Alamos National Laboratory, Sandia National Laboratories, and the USGS. A good understanding of the stratigraphy, structure, geochemistry, and physical properties of the rocks is essential for containment of underground nuclear tests. Many of the recent geologic studies at NTS, particularly in Yucca Flat, Pahute Mesa, and Mid Valley, are aimed at understanding subsurface geology to help ensure complete containment. The potential nuclear waste site at Yucca Mountain is located approximately 100 miles (160 km) by road northwest of Las Vegas, Nevada, and situated on land controlled by three Federal agencies; the Bureau of Land Management, the Department of Energy (Nevada Test Site), and the U.S. Air Force (Nellis Air Force Range).

Book Description
Origins of the Nevada Test Site was written in conjunction with the 50th anniversary commemoration of the Nevada Test Site. The history was released at the official celebration held in Las Vegas, Nevada, on December 18, 2000, fifty years after President Harry S. Truman formally designated the site as the location for conducting nuclear weapons tests within the continental United States.
