In 2008-9, a 14-in. natural gas liquids pipeline was constructed in Colorado and Wyoming. Alpine Archaeological Consultants, Inc. was hired to survey the route; the major research themes presented here synthesize chronometric and spatial information, subsistence, prehistoric technology, small cultural features, and prehistoric architecture.

The book offers a modern, comprehensive, and holistic view of natural gas seepage, defined as the visible or invisible flow of gaseous hydrocarbons from subsurface sources to Earth’s surface. Beginning with definitions, classifications for onshore and offshore seepage, and fundamentals on gas migration mechanisms, the book reports the latest findings for the global distribution of gas seepage and describes detection methods. Seepage implications are discussed in relation to petroleum exploration, environmental impacts (hazards, pollution, atmospheric emissions, and past climate change), emerging scientific issues (abiotic gas and methane on Mars), and the role of seeps in ancient cultures. With an updated bibliography and an integrated analysis of available data, the book offers a new fundamental awareness - gas seepage is more widespread than previously thought and influences all of Earth’s external “spheres”, including the hydrosphere, atmosphere, biosphere, and anthroposphere.

First published in 1998. Did prehistoric humans walk to North America from Siberia? Who were the inhabitants of the spectacular Anasazi cliff dwellings in the Southwest and why did they disappear? Native Americans used acorns as a major food source, but how did they get rid of the tannic acid which is toxic to humans? How does radiocarbon dating work and how accurate is it? Written for the informed lay person, college-level student, and professional, Archaeology of Prehistoric Native America: An Encyclopedia is an important resource for the study of the earliest North Americans; including facts, theories, descriptions, and speculations on the ancient nomads and hunter-gathers that populated continental North America.

Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

Atlas of Structural Geology features a broad and inclusive range of high-quality meso- and micro-scale full-color photographs, descriptions, and captions related to the deformation of rocks and geologic structures. It is a multi-contributed, comprehensive reference that includes submissions from many of the world's leading structural geologists, making it the most thorough and comprehensive reference available to the scientific community. All types of structures are featured, including structures related to ductile and brittle shear zones, sigma- and delta-structures, mineral fish, duplexes and trapezoids, shear related folds, and flanking structures in meso- and micro-scales. A stunning collection of the world's most beautiful and arresting geologic structures, the Atlas of Structural Geology is the ideal aid in the retention of key concepts in geology. - Presents more than 250 top-quality, full-color photographs contributed by the world's most respected structural geologists - Features a broad range of morphological variations of geologic structures, making it the most up-to-date and inclusive reference of its kind - Edited by a structural geologist with 14 years of experience in related research and instruction - Aids researchers in developing mathematical and analogue models on the peculiarity and uniqueness of the world's most iconic structures
