Depositional history of continental Eocene rocks in an intermontane basin of Central Rocky Mountains.

Compiled for the 2011 joint meeting of the GSA Rocky Mountain and Cordilleran Sections, this field guide provides an introduction to some of the remarkable geology of the Rocky Mountain and Cordillera regions.

A photographic and multidisciplinary study of one of America’s last undeveloped—and most endangered—landscapes, edited by a Pulitzer Prize–winning author. A vast expanse of rock formations, sand dunes, and sagebrush in central and southwest Wyoming, the little-known Red Desert is one of the last undeveloped landscapes in the United States, as well as one of the most endangered. It is a last refuge for many species of wildlife. Sitting atop one of North America's largest untapped reservoirs of natural gas, the Red Desert is a magnet for energy producers who are damaging its complex and fragile ecosystem in a headlong race to open a new domestic source of energy and reap the profits. To capture and preserve what makes the Red Desert both valuable and scientifically and historically interesting, writer Annie Proulx and photographer Martin Stupich enlisted a team of scientists and scholars to join them in exploring the Red Desert through many disciplines: geology, hydrology, paleontology, ornithology, zoology, entomology, botany, climatology, anthropology, archaeology, sociology, and history. Their essays reveal many fascinating, often previously unknown facts about the Red Desert—everything from the rich pocket habitats that support an amazing diversity of life to engrossing stories of the transcontinental migrations that began in prehistory and continue today on I-80—which bisects the Red Desert. Complemented by Martin Stupich’s photo-essay, which portrays both the beauty and the devastation that characterize the region today, Red Desert bears eloquent witness to a unique landscape in its final years as a wild place./

The geologic record contains evidence of greenhouse climates in the earth's past, and by studying these past conditions, we can gain greater understanding of the forcing mechanisms and feedbacks that influence today's climate. Leading experts in paleoclimatology combine in one integrated volume new and state-of-the-art paleontological, geological, and theoretical studies to assess intervals of global warmth. The book reviews what is known about the causes and consequences of globally warm climates, demonstrates current directions of research on warm climates, and outlines the central problems that remain unresolved. The chapters present new research on a number of different warm climate intervals from the early Paleozoic to the early Cenozoic. The book will be of great interest to researchers in paleoclimatology, and it will also be useful as a supplementary text on advanced undergraduate or graduate level courses in paleoclimatology and earth science.
