Book Description
"The Las Vegas Formation was established in 1965 to designate the distinctive light-colored, fine-grained, fossil-bearing sedimentary deposits exposed in and around the Las Vegas Valley, Nevada. In a coeval designation, the sediments were subdivided into informal units with stratigraphic and chronologic frameworks that have persisted in the literature. Use of the Las Vegas Formation name over the past half century has been hampered because of the lack of a robust definition and characterization of the entire lithostratigraphic sequence and its geographic distribution and chronology. This study evaluates and describes deposits attributed to the Las Vegas Formation with detailed stratigraphy, sedimentology, and field relations"--Provided by publisher.

Book Description
"You can't really know the place where you live until you know the shapes and origins of the land around you. To feel truly at home in the Bay Area, read Doris Sloan's intriguing stories of this region's spectacular, quirky landscapes."—Hal Gilliam, author of Weather of the San Francisco Bay Region "This is a fascinating look at some of the world's most complex and engaging geology. I highly recommend this book to anyone interested in an understanding of the beautiful landscape and dynamic geology of the Bay Area."—Mel Erskine, geological consultant "This accessible summary of San Francisco Bay Area geology is particularly timely. We are living in an age where we must deal with our impact on our environment and the impact of the environment on us. Earthquake hazards, and to a lesser extent landslide hazards, are well known, but the public also needs to be aware of other important engineering and environmental impacts and geologic resources. This book will allow Bay Area residents to make more intelligent decisions about the geological issues affecting their lives."—John Wakabayashi, geological consultant

Book Description
The book includes six chapters that cover Virginia history from initial settlement through the 20th century plus one that deals with the important role of underwater archaeology. Written by prominent archaeologists with research experience in their respective topic areas, the chapters consider important issues of Virginia history and consider how the discipline of historic archaeology has addressed them and needs to address them . Changes in research strategy over time are discussed , and recommendations are made concerning the need to recognize the diverse and often differing roles and impacts that characterized the different regions of Virginia over the course of its historic past. Significant issues in Virginia history needing greater study are identified.

Book Description
National parks are different from other federal lands in the United States. Beginning in 1872 with the establishment of Yellowstone, they were largely set aside to preserve for future generations the most spectacular and inspirational features of the country, seeking the best representative examples of major ecosystems such as Yosemite, geologic forms such as the Grand Canyon, archaeological sites such as Mesa Verde, and scenes of human events such as Gettysburg. But one type of habitat--the desert--fell short of that goal in American eyes until travel writers and the Automobile Age began to change that perception. As the Park Service began to explore the better-known Mojave and Colorado deserts of southern California during the 1920s for a possible desert park, many agency leaders still carried the same negative image of arid lands shared by many Americans--that they are hostile and largely useless. But one wealthy woman--Minerva Hamilton Hoyt, from Pasadena--came forward, believing in the value of the desert, and convinced President Franklin D. Roosevelt to establish a national monument that would protect the unique and iconic Joshua trees and other desert flora and fauna. Thus was Joshua Tree National Monument officially established in 1936, with the area later expanded in 1994 when it became Joshua Tree National Park. Since 1936, the National Park Service and a growing cadre of environmentalists and recreationalists have fought to block ongoing proposals from miners, ranchers, private landowners, and real estate developers who historically have refused to accept the idea that any desert is suitable for anything other than their consumptive activities. To their dismay, Joshua Tree National Park, even with its often-conflicting land uses, is more popular today than ever, serving more than one million visitors per year who find the desert to be a place worthy of respect and preservation.

Book Description
John Muir, America's pioneer conservationist and father of the national park system, was a man of considerable literary talent. As he explored the wilderness of the western part of the United States for decades, he carried notebooks with him, narrating his wanderings, describing what he saw, and recording his scientific researches. This reprint of his journals, edited by Linnie Marsh Wolfe in 1938 and long out of print, offers an intimate picture of Muir and his activities during a long and productive period of his life. The sixty extant journals and numerous notes in this volume were written from 1867 to 1911. They start seven years after the time covered in The Story of My Boyhood and Youth, Muir's uncompleted autobiography. The earlier journals capture the essence of the Sierra Nevada and Alaska landscapes. The changing appearance of the Sierras from Sequoia north and beyond the Yosemites enthralled Muir, and the first four years of the journals reveal his dominating concern with glacial action. The later notebooks reflect his changes over the years, showing a mellowing of spirit and a deep concern for human rights. Like all his writings, the journals concentrate on his observations in the wilderness. His devotion to his family, his many warm friendships, and his many-sided public life are hardly mentioned. Very little is said about the quarter-century battle for national parks and forest reserves. The notebooks record, in language fuller and freer than his more formal writings, the depth of his love and transcendental feeling for the wilderness. The rich heritage of his native Scotland and the unconscious music of the poetry of Burns, Milton, and the King James Bible permeate the language of his poetic fancy. In his later life, Muir attempted to sort out these journals and, at the request of friends, published a few extracts. A year after his death in 1914, his literary executor and biographer, William Frederick Badè, also published episodes from the journals. Linnie Marsh Wolfe set out to salvage the best of his writings still left unpublished in 1938 and has thus added to our understanding of the life and thought of a complex and fascinating American figure.

Book Description
In this new volume, the results of Rex E. Gerald’s 1957 excavations at the Davis Ranch Site in southeastern Arizona’s San Pedro River Valley are reported in their entirety for the first time. Annotations to Gerald’s original manuscript in the archives of the Amerind Museum and newly written material place Gerald’s work in the context of what is currently known regarding the late thirteenth-century Kayenta diaspora and the relationship between Kayenta immigrants and the Salado phenomenon. Data presented by Gerald and other contributors identify the site as having been inhabited by people from the Kayenta region of northeastern Arizona and southeastern Utah. The results of Gerald’s excavations and Archaeology Southwest’s San Pedro Preservation Project (1990–2001) indicate that the people of the Davis Ranch Site were part of a network of dispersed immigrant enclaves responsible for the origin and spread of Roosevelt Red Ware pottery, the key material marker of the Salado phenomenon. A companion volume to Charles Di Peso’s 1958 publication on the nearby Reeve Ruin, archaeologists working in the U.S. Southwest and other researchers interested in ancient population movements and their consequences will consider this work an essential case study.
