Henry Darwin Rogers was one of the first professional geologists in the United States. He directed two of the earliest state geological surveys--New Jersey and Pennsylvania--in the mid-1830s. His major interest was Pennsylvania, with its Appalachian Mountains, which Rogers saw as great folds of sedimentary rock. He belived that an interpretation of these folds would lead to an understanding of the dynamic processes that had shaped the earth. From Rogers' efforts to explain these Pennsylvania folds came the first uniquely American theory of mountain elevation, a theory that Rogers personally considered his most significant achievement.
Northern Utah’s Wasatch Mountains are popular destinations for outdoor enthusiasts in every season. These mountains rise spectacularly from the relatively flat valley floor to thirteen peaks over 11,000 feet in elevation. An additional nineteen peaks rise more than 10,000 feet in elevation. Although many hiking guides exist for the Wasatch Mountains, there has been no guide book that focuses on the geologic features visible from the trails—until now.
Written by a recognized authority on the geology of the Wasatch Mountains, this guide is meant to enrich the experience of outdoor enthusiasts who want to understand the geological history and development of the Wasatch range. The first section of the book introduces the major geological time periods—the record of mountain building events from oldest to youngest, the effects of glaciation, and the development of the present topography. It then follows with a descriptive trail guide for each major trail system, including Mill Creek and Neffs Canyons, Mount Olympus, Little and Big Cottonwood Canyons, and Bells Canyon. Trail length, elevation gain, relative difficulty, and major geological features are outlined for each trail. Now you can hike these trails with the answers to all your geologic questions right at your fingertips.
Cradled among the world’s highest mountains—and sheltering one of its most devout religious communities—Tibet is, for many of us, an ultimate destination, a place that touches the heavens, a place only barely in our world, at its very end. In recent decades Western fascination with Tibet has soared, from the rise of Tibetan studies in academia to the rock concerts aimed at supporting its independence to the simple fact that most of us—far from any base camp—know exactly what a sherpa is. And yet any sustained look into Tibet as a place, any attempt to find one’s way around its high plateaus and through its deep history, will yield this surprising fact: we have barely mapped it. With this atlas, Karl E. Ryavec rights that wrong, sweeping aside the image of Tibet as Shangri-La and putting in its place a comprehensive vision of the region as it really is, a civilization in its own right. And the results are absolutely stunning.
The product of twelve years of research and eight more of mapmaking, A Historical Atlas of Tibet documents cultural and religious sites across the Tibetan Plateau and its bordering regions from the Paleolithic and Neolithic times all the way up to today. It ranges through the five main periods in Tibetan history, offering introductory maps of each followed by details of western, central, and eastern regions. It beautifully visualizes the history of Tibetan Buddhism, tracing its spread throughout Asia, with thousands of temples mapped, both within Tibet and across North China and Mongolia, all the way to Beijing. There are maps of major polities and their territorial administrations, as well as of the kingdoms of Guge and Purang in western Tibet, and of Derge and Nangchen in Kham. There are town plans of Lhasa and maps that focus on history and language, on population, natural resources, and contemporary politics.
Extraordinarily comprehensive and absolutely gorgeous, this overdue volume will be a cornerstone in cartography, Asian studies, Buddhist studies, and in the libraries or on the coffee tables of anyone who has ever felt the draw of the landscapes, people, and cultures of the highest place on Earth.
Gazing up at the heavens from our backyards or a nearby field, most of us see an undifferentiated mess of stars—if, that is, we can see anything at all through the glow of light pollution. Today’s casual observer knows far less about the sky than did our ancestors, who depended on the sun and the moon to tell them the time and on the stars to guide them through the seas. Nowadays, we don’t need the sky, which is good, because we’ve made it far less accessible, hiding it behind the skyscrapers and the excessive artificial light of our cities.
How We See the Sky gives us back our knowledge of the sky, offering a fascinating overview of what can be seen there without the aid of a telescope. Thomas Hockey begins by scanning the horizon, explaining how the visible universe rotates through this horizon as night turns to day and season to season. Subsequent chapters explore the sun’s and moon’s respective motions through the celestial globe, as well as the appearance of solstices, eclipses, and planets, and how these are accounted for in different kinds of calendars. In every chapter, Hockey introduces the common vocabulary of today’s astronomers, uses examples past and present to explain them, and provides conceptual tools to help newcomers understand the topics he discusses.
Packed with illustrations and enlivened by historical anecdotes and literary references, How We See the Sky reacquaints us with the wonders to be found in our own backyards.
