Download or read book Sand written by Michael Welland and published by Univ of California Press. This book was released on 2009-01-15 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: From individual grains to desert dunes, from the bottom of the sea to the landscapes of Mars, and from billions of years in the past to the future, this is the extraordinary story of one of nature's humblest, most powerful, and most ubiquitous materials. Told by a geologist with a novelist's sense of language and narrative, Sand examines the science—sand forensics, the physics of granular materials, sedimentology, paleontology and archaeology, planetary exploration—and at the same time explores the rich human context of sand. Interwoven with tales of artists, mathematicians, explorers, and even a vampire, the story of sand is an epic of environmental construction and destruction, an adventure in staggering scales of time and distance, yet a tale that encompasses the ordinary and everyday. Sand, in fact, is all around us—it has made possible our computers, buildings and windows, toothpaste, cosmetics, and paper, and it has played dramatic roles in human history, commerce, and imagination. In this luminous, kinetic, revelatory account, we do indeed find the world in a grain of sand.
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 294 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 from Sand Creek written by Simon J. Ortiz and published by University of Arizona Press. This book was released on 2022-09-13 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The massacre of Cheyenne and Arapaho women and children by U.S. soldiers at Sand Creek in 1864 was a shameful episode in American history, and its battlefield was proposed as a National Historic Site in 1998 to pay homage to those innocent victims. Poet Simon Ortiz had honored those people seventeen years earlier in his own way. That book, from Sand Creek, is now back in print. Originally published in a small-press edition, from Sand Creek makes a large statement about injustices done to Native peoples in the name of Manifest Destiny. It also makes poignant reference to the spread of that ambition in other parts of the world—notably in Vietnam—as Ortiz asks himself what it is to be an American, a U.S. citizen, and an Indian. Indian people have often felt they have had no part in history, Ortiz observes, and through his work he shows how they can come to terms with this feeling. He invites Indian people to examine the process they have experienced as victims, subjects, and expendable resources—and asks people of European heritage to consider the motives that drive their own history and create their own form of victimization. Through the pages of this sobering work, Ortiz offers a new perspective on history and on America. Perhaps more important, he offers a breath of hope that our peoples might learn from each other: This America has been a burden of steel and mad death, but, look now, there are flowers and new grass and a spring wind rising from Sand Creek.

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 The World in a Grain written by Vince Beiser and published by Penguin. This book was released on 2019-08-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: A finalist for the PEN/E. O. Wilson Literary Science Writing Award The gripping story of the most important overlooked commodity in the world--sand--and the crucial role it plays in our lives. After water and air, sand is the natural resource that we consume more than any other--even more than oil. Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. From Egypt's pyramids to the Hubble telescope, from the world's tallest skyscraper to the sidewalk below it, from Chartres' stained-glass windows to your iPhone, sand shelters us, empowers us, engages us, and inspires us. It's the ingredient that makes possible our cities, our science, our lives--and our future. And, incredibly, we're running out of it. The World in a Grain is the compelling true story of the hugely important and diminishing natural resource that grows more essential every day, and of the people who mine it, sell it, build with it--and sometimes, even kill for it. It's also a provocative examination of the serious human and environmental costs incurred by our dependence on sand, which has received little public attention. Not all sand is created equal: Some of the easiest sand to get to is the least useful. Award-winning journalist Vince Beiser delves deep into this world, taking readers on a journey across the globe, from the United States to remote corners of India, China, and Dubai to explain why sand is so crucial to modern life. Along the way, readers encounter world-changing innovators, island-building entrepreneurs, desert fighters, and murderous sand pirates. The result is an entertaining and eye-opening work, one that is both unexpected and involving, rippling with fascinating detail and filled with surprising characters.

Download or read book The Weight of Sand written by Edith Blais and published by Greystone Books Ltd. This book was released on 2021-09-21 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: A radiant, unforgettable memoir of one woman’s 450 days spent in captivity, and her defiant refusal to have her humanity stripped away. When Edith meets Luca in a small Northern town, the two connect instantly. Under the Northern Lights, they develop a deep friendship over their shared passions: travel, living off the land, a bohemian life. In search of wanderlust, they embark on an epic road trip from Italy to Togo, where they will join their friend’s sustainable farming project. Upon arriving on the African continent, they change their itinerary and drive through Africa’s Sahel region, a haven for militant groups, where they are surrounded and captured. Little was known about Edith’s and Luca’s fate until they reappeared in Mali more than one year later, having mysteriously escaped their captors. Now, Edith shares her harrowing story with the world for the first time—complete with the poems that became a lifeline for her in captivity, which she wrote in secret with a pen borrowed from another hostage. Against the stunning but cruel backdrop of the desert, Edith recounts her months as a hostage: the oppressive heat, violent sandstorms, constant relocations, hunger strikes, and her eventual heart-pounding escape. Separated from Luca early on, she finds solidarity and comfort with a group of other female hostages, who lend her a pen to write poetry, a creative outlet that helps save her life. Edith is steadfast in her will to remain sane: she reveals her dedication to her art, and her striking ability to unsettle her captors and identify their vulnerabilities. A compelling descent into a strange, brutal universe, The Weight of Sand is ultimately a life-affirming book and a poetic celebration of one woman’s resilience.
Download or read book Sand Queen written by Helen Benedict and published by Soho Press. This book was released on 2011-08-02 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This novel of female friendship in the midst of war is “The Things They Carried for women in Iraq” (The Boston Globe). Nineteen-year-old Kate Brady joined the army to bring honor to her family and to the Middle East. Instead, she finds herself in a forgotten corner of the Iraq desert in 2003, guarding a makeshift American prison. There, Kate meets Naema Jassim, an Iraqi medical student whose father and little brother have been detained in the camp. Kate and Naema promise to help each other, but the war soon strains their intentions. Like any soldier, Kate must face the daily threats of combat duty, but as a woman, she is in equal danger from the predatory men in her unit. Naema suffers bombs, starvation, and the loss of her home and family. As the two women struggle to survive and hold on to the people they love, each comes to have a drastic and unforeseeable effect on the other’s life. From the author of Wolf Season and The Lonely Soldier, and informed by numerous interviews with those who were there, Sand Queen is a “heartbreaking, vivid story of the particular difficulties of being not just a soldier, but a female soldier” (Bustle).
Download or read book Wind as a Geological Process written by Ronald Greeley and published by CUP Archive. This book was released on 1987-08-28 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an account of geological aspects of windblown material. Aeolian processes play an important role in modifying the surface of the Earth, and they are also active on Mars. Additionally, they are thought to occur on Venus and possibly Titan as well. The authors describe the following aspects: wind as a geological process, the aeolian environment, physics of particle motion, aeolian abrasion and erosion; aeolian sand deposits and bedforms, interaction of wind and topography and windblown dust. A particular strength of the book is that it deals with aeolian processes in a planetary context, rather than as a purely terrestrial phenomenon. In so doing, the authors ably demonstrate how we can gain better understanding of the Earth through comparative planetology. This paperback reissue will enable the book to be used as a text for advanced students in planetary science. Special terms are defined when they are first used. There is a glossary and an exhaustive bibliography.
Download or read book A Study of Global Sand Seas written by Edwin D. McKee and published by . This book was released on 2004-06-01 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early descriptions and considerations of the characteristics of modern eolian sand deposits, mostly in the great sand seas of the world, date back to the 1880's and 1890's, when pioneer geologists and explorers wrote their classic papers on desert dunes. One or two decades later, interest in eolian processes greatly increased when wind-formed deposits were recognized in ancient sandstones in many parts of the world and in rocks of many ages. Throughout the 20th century, as the science of geology has expanded and the programs of the U.S. Geological Survey have proliferated to keep pace, dune studies have had a similar growth. Work was initially concentrated mostly on the description of dune forms or morphology and on analysis of textural features; by midcentury, however, major contributions had been made to the physics of eolian sand by detailed studies and interpretations of minor eolian structures, by statistical analyses of cross-strata dip directions, and by the development of systems for dune classification. Most recently, interest has been renewed in detailed grain studies, in the study of cross-strata, and in interpretation of dune patterns by means of aerial photographs and Landsat imagery. A major feature of this report on global sand seas is the compilation and comparison of available data based on many different methods of investigation. The application of these studies to economic problems, which is described in one chapter, clearly illustrates the importance of eolian deposits to our present culture and to human welfare. H.
