The Rio Chama


Book Description

In the course of the hundreds of Rio Chama rafting trips that we've logged during the last 30 years, none of us has ever had a bad trip. Such is the magic of the Rio Chama. No matter the weather, the water level, the season, the crowded Big Eddy boat ramp on a blistering Sunday afternoon, or even the coffee forgotten at home, the Rio Chama remains "The People's River." Its stunning beauty, plus its exceptional camping, user-friendly whitewater, and mostly predictable flows, combine to create one of the Southwest's premiere, multi-day, river running experiences.The spectacular, towering canyon walls of the Wild & Scenic section through the remote Chama River Canyon Wilderness is New Mexico's own "Grand Canyon." The geology of the Rio Chama is so exceptional that this river is ideally suited for a river guide with a geological theme. And so, following the release of the Rio Grande geologic river guide in 2011, we turned our (part-time) attention to the Rio Chama. Although most Rio Chama recreation is focused on the El Vado to Big Eddy stretch, thedecision was easily made to include the entire boatable section, from the highlands in Colorado to the confluence with the Rio Grande, as each section of the river displays its own visual spectacles and assortment of adventures. Plus, the geology is magnificent and diverse along the entire length of the river.




Earth Matters


Book Description

For courses in Earth Science, Physical Geology, Physical Geography, Earth System Science and Environmental Philosophy. This collection of essays by scholars in both the earth sciences and philosophy discusses the connections between the earth sciences and contemporary culture, and the changing role of the earth sciences in society.




Minerals, Critical Minerals, and the U.S. Economy


Book Description

Minerals are part of virtually every product we use. Common examples include copper used in electrical wiring and titanium used to make airplane frames and paint pigments. The Information Age has ushered in a number of new mineral uses in a number of products including cell phones (e.g., tantalum) and liquid crystal displays (e.g., indium). For some minerals, such as the platinum group metals used to make cataytic converters in cars, there is no substitute. If the supply of any given mineral were to become restricted, consumers and sectors of the U.S. economy could be significantly affected. Risks to minerals supplies can include a sudden increase in demand or the possibility that natural ores can be exhausted or become too difficult to extract. Minerals are more vulnerable to supply restrictions if they come from a limited number of mines, mining companies, or nations. Baseline information on minerals is currently collected at the federal level, but no established methodology has existed to identify potentially critical minerals. This book develops such a methodology and suggests an enhanced federal initiative to collect and analyze the additional data needed to support this type of tool.




Effects of Nuclear Earth-Penetrator and Other Weapons


Book Description

Underground facilities are used extensively by many nations to conceal and protect strategic military functions and weapons' stockpiles. Because of their depth and hardened status, however, many of these strategic hard and deeply buried targets could only be put at risk by conventional or nuclear earth penetrating weapons (EPW). Recently, an engineering feasibility study, the robust nuclear earth penetrator program, was started by DOE and DOD to determine if a more effective EPW could be designed using major components of existing nuclear weapons. This activity has created some controversy about, among other things, the level of collateral damage that would ensue if such a weapon were used. To help clarify this issue, the Congress, in P.L. 107-314, directed the Secretary of Defense to request from the NRC a study of the anticipated health and environmental effects of nuclear earth-penetrators and other weapons and the effect of both conventional and nuclear weapons against the storage of biological and chemical weapons. This report provides the results of those analyses. Based on detailed numerical calculations, the report presents a series of findings comparing the effectiveness and expected collateral damage of nuclear EPW and surface nuclear weapons under a variety of conditions.







Geological and Geotechnical Engineering in the New Millennium


Book Description

The field of geoengineering is at a crossroads where the path to high-tech solutions meets the path to expanding applications of geotechnology. In this report, the term "geoengineering" includes all types of engineering that deal with Earth materials, such as geotechnical engineering, geological engineering, hydrological engineering, and Earth-related parts of petroleum engineering and mining engineering. The rapid expansion of nanotechnology, biotechnology, and information technology begs the question of how these new approaches might come to play in developing better solutions for geotechnological problems. This report presents a vision for the future of geotechnology aimed at National Science Foundation (NSF) program managers, the geological and geotechnical engineering community as a whole, and other interested parties, including Congress, federal and state agencies, industry, academia, and other stakeholders in geoengineering research. Some of the ideas may be close to reality whereas others may turn out to be elusive, but they all present possibilities to strive for and potential goals for the future. Geoengineers are poised to expand their roles and lead in finding solutions for modern Earth systems problems, such as global change, emissions-free energy supply, global water supply, and urban systems.

Origin and Evolution of Earth


Book Description

Questions about the origin and nature of Earth and the life on it have long preoccupied human thought and the scientific endeavor. Deciphering the planet's history and processes could improve the ability to predict catastrophes like earthquakes and volcanic eruptions, to manage Earth's resources, and to anticipate changes in climate and geologic processes. At the request of the U.S. Department of Energy, National Aeronautics and Space Administration, National Science Foundation, and U.S. Geological Survey, the National Research Council assembled a committee to propose and explore grand questions in geological and planetary science. This book captures, in a series of questions, the essential scientific challenges that constitute the frontier of Earth science at the start of the 21st century.




Disappearing Earth


Book Description

One of The New York Times 10 Best Books of the Year National Book Award Finalist Finalist for the National Book Critics Circle John Leonard Prize Finalist for the Center for Fiction First Novel Prize Finalist for the New York Public Library's Young Lions Fiction Award National Best Seller "Splendidly imagined . . . Thrilling" --Simon Winchester "A genuine masterpiece" --Gary Shteyngart Spellbinding, moving--evoking a fascinating region on the other side of the world--this suspenseful and haunting story announces the debut of a profoundly gifted writer. One August afternoon, on the shoreline of the Kamchatka peninsula at the northeastern edge of Russia, two girls--sisters, eight and eleven--go missing. In the ensuing weeks, then months, the police investigation turns up nothing. Echoes of the disappearance reverberate across a tightly woven community, with the fear and loss felt most deeply among its women. Taking us through a year in Kamchatka, Disappearing Earth enters with astonishing emotional acuity the worlds of a cast of richly drawn characters, all connected by the crime: a witness, a neighbor, a detective, a mother. We are transported to vistas of rugged beauty--densely wooded forests, open expanses of tundra, soaring volcanoes, and the glassy seas that border Japan and Alaska--and into a region as complex as it is alluring, where social and ethnic tensions have long simmered, and where outsiders are often the first to be accused. In a story as propulsive as it is emotionally engaging, and through a young writer's virtuosic feat of empathy and imagination, this powerful novel brings us to a new understanding of the intricate bonds of family and community, in a Russia unlike any we have seen before.
