Download or read book The San Luis Valley written by and published by University of Arizona Press. This book was released on 2005 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Aeolian Sand and Sand Dunes written by and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sea of Sand written by Michael M. Geary and published by University of Oklahoma Press. This book was released on 2016-03-31 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Dune Worlds written by Ralph D. Lorenz and published by Springer Science & Business Media. This book was released on 2014-04-22 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes how sand dunes work, why they are the way they are in different settings, and how they are being studied. Particular attention is paid to their formation and appearance elsewhere in the solar system. New developments in knowledge about dunes make for an interesting story – like the dunes themselves, dune science is dynamic – and the visual appeal of Aeolian geomorphology ensures that this is an attractive volume. The book is divided into 4 parts, the first of which introduces dunes as a planetary phenomenon, showing a landscape reflecting the balance of geological processes – volcanism, impact, tectonics, erosion, deposition of sediments. Dunes are then considered as emergent dynamical systems: the interaction of sand and wind conspires to generate very characteristic and reproducible shapes. Analogies are given with other emergent structures such as patterned ground before the influence of dunes on desert peoples and infrastructure is studied, together with their use as forensic climatological indicators. Dune Physics is looked at with regard to the mechanics of sand, the physics of wind, saltation – interaction of sand and air – dunes versus ripples and transverse Aeolian ridges, the classification of dune morphology and the sources and sinks of sand. Dune Trafficability considers soil mechanics, effects on mobility on Earth, Mars and elsewhere. In the second part, Earth, Mars, Titan and other moons and planets are examined, beginning with a survey of the major deserts and dunefields on Earth. The authors then turn to Mars and its environment, sediment type, dune stratigraphy, sediment source and sinks and the association of dunes with topographic features. Titan follows - its thick, cold atmosphere, methane dampness, low gravity, morphology – interaction with topography and the implications of dunes for climate and winds. Dunes elsewhere conclude this part. There are few dunefields on Venus, but there is a .possibility of Aeolian transport on Triton and volcanic-related windstreaks on Io.

Download or read book Sand Dunes of the Northern Hemisphere written by Qi Lu and published by CRC Press. This book was released on 2023-03-10 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Great Sand Dunes National Park written by Mike Butler and published by Arcadia Publishing. This book was released on 2013-04-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southern Colorados unique Great Sand Dunes rise to a height of 750 feet above the San Luis Valley floor and are the nations highest dunes not adjacent to an ocean or lake. The sweeping dunes were protected as a national monument in 1932 and as a national park in 2000. From prehistoric hunter-gatherers to the historic Ute Indian tribe, inhabitants have long used the resources of the land around the dunes. Zebulon Pike was the first American explorer to witness the dunes in 1807, followed by a long procession of other explorers, ranchers, and miners. Today, visitors from around the world come to climb up and slide down the dunes in Great Sand Dunes National Park and Preserve.

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.
Download or read book Sand Dunes of the Northern Hemisphere Distribution Formation Migration and Management written by Lu Qi and published by CRC Press. This book was released on 2024-01-09 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 2 of the book ‘Sand Dunes of the Northern Hemisphere’ is sub-titled Characteristics, Dynamics and Provenance of Sand Dunes in the Northern Hemisphere. It brings together a vast body of information and insight into sand dune and desert systems from North Asia, Central Asia, North Africa and the Middle East. Chapters from the Russian Federation include studies on dune systems within the permafrost zone and there is a case study from temperate zone dune system in coastal Japan. Volume 2: Characteristics, Dynamics and Provenance of Sand Dunes in the Northern Hemisphere of 16 chapters in three Parts, focusses on Saharan Africa, Egypt, and Middle East and gives attention to sand mobility and encroachment with case studies from a number of countries where these matters are of concern. We also include chapters on the remote dunes in the permafrost zone and in the hyper-arid deserts of Iran. Case studies are used to highlight the characteristics of dunes and their interaction with humans in several widely divergent settings. Volume 2 concludes with some musing on the value of study of the past as key to the future and speculates on what the future might hold in the light of a warmer and drier Earth and a rise in sea level that threaten large tracts of low-lying land with marine incursions and destruction from storm surge. PART 4 Sand Mobility and Encroachment The seven chapters in this Part examine the real-world impact of sand encroachment and dune migration on people and their economic activities and the health, welfare and financial implications related to destruction of infrastructure, including human habitations. PART 5 Sand Dune Landscapes Distribution, Formation and Management Seven Case studies from several geographic regions in Africa, the Middle East, north-east Asia are presented here to demonstrate the underlying mechanisms in dune formation and the diverse approaches to their management. Human impacts such as sand mining, tourism development, combine with natural forces like climate variability to challenge the realization of an optimum management strategy. PART 6 Concluding Thoughts: Coping with an Unknown Future from a Little-known Past The two chapters in Part 6 have special roles. We are privileged to publish new research findings that are summarized here in Chapter 38 from extensive and detailed work conducted in the Kyzyl Kum, and Karakum sand seas of Central Asia. There is a strong belief that further study of the little-known past such as revealed in this study could unlock clues as to what a future Earth might look like. This leads on to speculation in Chapter 39 about the implications of what we already know about global change (not only climate change) and the impact of the Anthropocene on the dune systems, both inland and coastal. Sea level rise, marine incursions and an increase in extreme weather events will affect dune systems and sand seas on the Northern Hemisphere (and beyond).

This book was released on 2012-09-17 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the development of temperate coastal sand dunes and the way these have been influenced by human activity. The different states in which the habitat exists both for the beach/foredune and inland dune are reviewed against the pressures exerted upon them. Options for management are considered and the likely consequences of taking a particular course of action highlighted. These options include traditional approaches to the conservation and management of wildlife and landscapes as well as habitat restoration. The way the value of the areas changes under different management regimes is considered mainly from an environmental perspective. Consideration is given to new approaches to management and restoration including adopting a more dynamic approach. Audience This book will be of interest to academics, students and professionals concerned with policy formulation and /or actively managing coastal areas.
