It is more than half a century since the publication of R. A. Bagnold’s classic book The physics of blown sand and desert dunes, and it is a tribute to the quality of Bagnold’s work that many of the fundamental principles which he developed - main valid today. His book continues to be essential reading for any serious s- dent of aeolian processes. However, the past two decades have seen an explosion in the scale of research dealing with aeolian transport processes, sediments, and landforms. Some of this work has been summarized in review papers and edited conference proceedings, but this book provides the rst attempt to review the whole eld of aeolian sand research. Inevitably, it has not been possible to cover all - pects in equal depth, and the balance of included material naturally re ects the - thors’ own interests to a signi cant degree. However, our aim has been to provide as broad a perspective as possible, and to provide an entry point to an extensive mul- disciplinary scienti c literature, some of which has not been given the attention it deserves in earlier textbooks and review papers. Many examples are drawn from existing published work, but the book also makes extensive use of our own research in the Middle East, Australia, Europe, and North America. The book has been written principally for use by advanced undergraduates, po- graduates, and more senior research workers in geomorphology and sedimentology.

It is a high valley edged by serrated peaks, a remote expanse the size of Connecticut lying, as if forgotten, between two mountain ranges. Here, North AmericaÕs tallest sand dunes blow against glacier-gouged summits, the Rio Grande begins its long journey from snowflake to saltwater, and vast reaches of desert scrub hide verdant pocket wetlands. ColoradoÕs San Luis Valley is not a place for the timid. Sizzling hot in summer, frigid cold in winter, this huge landscape is humbling in its openness, a place defined by the rhythms of natureÑand by the thrust and parry of male courting female in the ritual dance of sandhill cranes. These majestic birds arrive by the thousands twice a year to feed, rest, and socialize in the valleyÕs wetlandsÑinvisible except from the airÑand their cries temper the constant wind. Susan Tweit lives in the high desert of southern Colorado not far from the valleyÕs dunes and wetlands. With the precision of a scientist and the passion of a poet, she guides readers through this land of sand dunes and sandhill cranes, describing its natural features and tracing its human history from buffalo hunters and conquistadors to Hispanic farming communities and UFO observatories. And in stunning images, photographer Glenn Oakley brings his intimate feel for light and landscape to portraying not only the subtle beauty of this high-desert sanctuary but also the grandeur of the cranes in flight. As an intimate look at Great Sand Dunes National Park and Preserve and the San Luis Valley, this book reveals a desert place as seductive and sobering as existence itself.

For three years, John Weller captured the Great Sand Dunes with his extraordinary photography and vivid stories. Here is his masterly result in a phenominal book to celebrate our nation's newest national park.

Sculpted into graceful contours by countless centuries of wind and water, the Great Sand Dunes sprawl along the eastern fringes of the vast San Luis Valley of south-central Colorado. Covering an area of nearly thirty square miles, they are the tallest aeolian, or wind-produced, dunes in North America, towering 750 feet above the valley floor. With the addition of the enormous Baca Ranch and other adjacent lands, the dunes—originally designated as a National Monument in 1932—attained official National Park status in 2004. In Sea of Sand, Michael M. Geary guides readers on a historical journey through this unique ecosystem, which includes an array of natural and cultural wonders, from the main dunefield and verdant wetlands to the summits of the Sangre de Cristo Mountains. Described by explorer Zebulon Pike as “a sea in a storm” and by frontier photographer William Henry Jackson as “a curious and very singular phase of nature’s freak,” the Great Sand Dunes are a nexus of more than 10,000 years of human history, from Paleolithic big-game hunters to nomadic Native Americans, from Spanish conquistadores and transcontinental explorers to hard-rock miners and modern-day tourists in motor homes. Like these successive waves of visitors, Sea of Sand follows the water, analyzing its critical role in the settlement and development of the region. Geary also describes the profound impact that waves of human use and settlement have had on the land—which ultimately inspired the early grassroots efforts by San Luis Valley citizens to protect the dunes from further exploitation. He examines as well the more recent legislative effort led by an unprecedented coalition of local, state, and federal agencies and organizations, including The Nature Conservancy and the National Park Service, to secure the Great Sand Dunes’ national park designation. Amply illustrated, Sea of Sand is the definitive history of the natural, cultural, and political forces that helped shape this incomparable landscape.

* Guidebook to hiking, biking, or climbing in the stunning Sangre de Cristo Mountains. * Details unlimited recreational opportunities for the park's 225,000 annual visitors * 210 color photographs and 40 color maps * Color-coded tabs and activity symbols for quick reference Nowhere else in North America do alpine tundra, tall forests of evergreen and aspen, and massive desert dunes meet so dramatically as in our nation's newest crown jewel. This book is the essential guide to one of the nation's newest national parks. Great Sand Dunes National Park and Preserve earned this status in 2003, and became an instant treasure both for Coloradans and vacationers everywhere.

Coastal zones are becoming increasingly topical (and politically sensitive) as they face relentless pressures from urban expansion, recreational development, and sea level rise due to climate change. This timely book provides a comprehensive introduction to the formation, dynamics, maintenance, and perpetuation of coastal sand dune systems. It describes the interactions between living organisms and the physical processes of geomorphology. A global range of examples enhance the book's international appeal. Based on the research presented in this book, simple to complex field studies and experiments could be designed at undergraduate and graduate levels to illustrate various biological principles. This accessible book is intended for a diverse audience; as an invaluable reference for researchers who study coastal dune systems and for novice researchers requiring a sound introduction to the subject. This book is suitable for both senior undergraduate and graduate students taking courses in coastal zone management, plant ecology, restoration ecology, and conservation biology, as well as the many professional ecologists and conservation biologists requiring a concise but authoritative overview of the topic. The book also will be of relevance and use to coastal managers, planners, naturalists, and anyone pursuing a greater understanding of coastal sand dunes.

This book in two volumes, and with a foreword by the renowned Professor M.A.J. Williams, draws on evidence from coastal and inland regions, including desert dunes, wind-blown dust, river and lake sediments, glacial moraines, plant and animal fossils, isotope geochemistry, soils and prehistoric archaeology to better understand the genesis and development of dunes systems in selected northern hemisphere sand dunes from Asia, Africa and the Middle East regions. The collection of research papers and case studies that are presented in this book provide the reader with a wealth of information about the distribution and types of sand dunes and an insight into the complexity of sand dune formation, migration and management. Research in many countries across the northern hemisphere shows that dunes, whether coastal or inland, are under pressure around the world. Much of the pressure comes from human activities, and the anthropogenic disturbance, when coupled with global warming and alterations to the amount, frequency and temporal distribution of precipitation could lead to more serious management challenges in the future. There is much that we still need to find out about the origin, genesis and development of sand dunes so that they can be managed better. The difficult and complex questions being repeatedly raised can be answered only by interdisciplinary endeavours. Geomorphologists, geologists, palaeontologists, climatologists, ecologists, and others, can work together on research projects that better define the origin, evolution and development of dunes, both inland and along the coasts. Many chapters in this book attempt to reconstruct past climatic changes in deserts and their margins at a variety of scales in space and time in the expectation that such information might assist in preparing us for future global warming and drying.

"With its comprehensive explanation of dune formation and variety, the book also includes information on activities at the dunes, including hiking, skiing, picnic and swimming areas, directions and parking, number of campsites, interesting and unique natural features found in and around each dune, and types of dune flora and fauna. Detailed maps provide a ready guide for all outdoor activities." "With nearly 50 duneland areas, from the remote to the well know, this book will inspire travelers to take a closer look at one of the most awesome natural features found in the state. Even those who think they know the dunes well will find this book an amazing resource for their trips back to a specific dune or their exploration of a new dune."--BOOK JACKET.

This atlas examines nearly every aspect of the natural history of the Nebraska Sand Hills, including Indian occupation, settlement, current range practices & the "cow-country" lifestyle. These 19,300 square miles comprise the largest dune area in the Western Hemisphere. The grass-stabilized dunes, some as high as 400 feet & as long as 20 miles, were formed by blowing sand during a surprisingly recent time, mostly the last 8,000 years. The climate ranges from subhumid in the east to semiarid in the west. The area is an ecological meeting ground, where species from different vegetative & faunal regions coexist, creating distinctive biological communities. The sandy soils & underlying sands & gravels have allowed for the accumulation of a vast quantity of groundwater, much of which "outcrops" at the surface. This accounts for another unique characteristic: the dry, dune-top prairie ecosystem beside a wetland, lake, or constantly flowing stream. "But this atlas is much more than an explanation of the climate & geology of the Sand Hills. Illustrated with wonderful color photos, fold-out maps, graphs & numerous charts, the book explores the entire ecology of the Sand Hills," said Francis Moul in his review for the DES MOINES REGISTER.
