Download or read book A Natural History of Oregon s Lake Abert in the Northwest Great Basin Landscape written by Ronald James Larson and published by University of Nevada Press. This book was released on 2023-12-12 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: A beautifully detailed exploration of flora and fauna. Author Ron Larson offers a natural history of a Great Basin landscape that focuses on the northern region including Lake Abert and Abert Rim, and the adjacent area in southcentral Oregon. Although the jewel of this landscape is a lake, the real story is the many plants and animals—from the very primitive, reddish, bacteria-like archaea that thrive only in its high-salinity waters to the Golden Eagles and ravens that soar above the desert. The untold species in and around the lake are part of an ecosystem shaped by ageless processes from massive lava flows, repeated drought, and blinding snowstorms. It is an environment rich with biotic and physical interconnections going back millions of years. The Great Basin, and in particular the Lake Abert region, is special and needs our attention to ensure it remains that way. We must recognize the importance of water for Great Basin ecosystems and the need to manage it better, and we must acknowledge how rich the Great Basin is in natural history. Salt lakes, wherever they occur, are valuable and provide critically important habitat for migratory water birds, which are unfortunately under threat from upstream water diversions and climate change. Larson’s book will help people understand that the Great Basin is unique and that wise stewardship is necessary to keep it unspoiled. The book is an essential reference source, drawing together a wide range of materials that will appeal to general readers and researchers alike.
Download or read book An American Heroine in the French Resistance written by Virginia D'Albert-Lake and published by Fordham Univ Press. This book was released on 2009-08-25 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: This account by a woman who fought the Nazis alongside her husband is “an indelible portrait of extraordinary strength of character” (The New Yorker). Virginia Roush fell in love with Philippe d’Albert-Lake during a visit to France in 1936; they married soon after. In 1943, they both joined the Resistance, where Virginia put her life in jeopardy as she sheltered downed airmen and later survived a Nazi prison camp. After the war, she stayed in France with Philippe, and was awarded the Légion d’Honneur and the Medal of Honor. This book includes two rare documents—Virginia’s diary of wartime France until her capture in 1944, and her prison memoir written immediately after the war. Together they offer “an invaluable record of the workings of the French Resistance by one of the very few American women who participated in it” (Providence Journal). “A sharply etched and moving story of love, companionship, commitment, and sacrifice . . . This beautifully edited diary and memoir throw an original light on the French Resistance.” —Robert Gildea, author of Marianne in Chains: In Search of the German Occupation, 1940–1945 “At once a stunning self-portrait and dramatic narrative of a valorous young American woman . . . an exciting and gripping story.” —Walter Cronkite
Download or read book Roadside Geology of Oregon written by Marli Bryant Miller and published by Roadside Geology. This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the first edition of Roadside Geology of Oregon was published in 1978, it was revolutionary�the first book in a series designed to educate, inspire, and wow nongeologists. Back then, the implications of plate tectonic theory were only beginning to shape geologic research and discussion. Geologists hadn�t yet learned that Oregon�s Klamath and Blue Mountains were pieces of far-traveled island arcs and ocean basins that had been piled against the growing North American continent. Steaming volcanoes, ghost forests, recent landslides, and towns heated with geothermal energy attest to Oregon�s still-prominent position at the edge of an active tectonic plate. Author, photographer, and geologist Marli Miller has written a completely new second edition based on the most up-to-date understanding of Oregon�s geology. Spectacular photographs showcase the state�s splendor while also helping readers understand geologic processes at work. Roadside Geology of Oregon, Second Edition, is a must-have for every Oregon resident, student, and rockhound.
Download or read book Geology of Pluvial Lake Chewaucan Lake County Oregon written by Ira Shimmin Allison and published by . This book was released on 1982 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pluvial Lake Chewaucan was a late Pleistocene lake, as much as 375 feet deep, covering 480 square miles in the northwestern part of the Great Basin in southern Oregon. The lake basin, now occupied by Summer Lake, Upper and Lower Chewaucan Marshes, and Lake Abert, was formed by down-dropped fault blocks bounded by imposing fault scarps, notably Winter Ridge and Abert Rim. Several large landslides occurred along the east side of Winter Ridge. Lake Chewaucan shore features include wave-cut cliffs and caves, beaches, terraces, bay bars, spits (as at The Narrows), and a huge alluvial fan built by Chewaucan River at Paisley. Later, at lower lake stages, part of the fan deposit of sand and gravel was distributed across four-mile-wide Paisley Flat, which subsequently became a divide between Winter Lake in the Summer Lake basin and ZX Lake (new name) in the Chewaucan Marshes-Lake Abert part of the Lake Chewaucan basin. Overflow from ZX Lake later cut a shallow channel across the divide enroute to Winter Lake. The bottom sediments of Lake Chewaucan are exposed mainly in the bluffs of Ana River, the main source of Summer Lake water. The stratigraphic section there is about 54 feet thick and composed mainly of silt, with numerous seams of sand, oolites, occasional pebbles, and many layers of volcanic ash, especially near the top. Fossils found in the area include 1) mammals and birds obtained from man-occupied caves near Paisley, 2) ostracods, diatoms, and small mollusks in the Ana River section, 3) similar tiny snail shells in a gravel pit north of the Ana Springs Reservoir, and 4) additional shells from the 4425-foot level near Ten Mile Butte east of Summer Lake. The snail shells have radiocarbon ages of>25,900, 22,000, and 17,500 years - all within the span of the Tioga-Pinedale glacial stage of the Sierra Nevada and the Rocky Mountains. The top 4520-foot shoreline, the 4485-foot beach and Paisley Caves, and the bulk of the Paisley fan may possibly be Tahoe in age, but the wave erosion of the Paisley fan, development of Paisley Flat, overflow from ZX Lake, and later formation of ZX Red House beach are assigned to Tioga-Pinedale time. The history of Lake Chewaucan is thought to be analogous to those of Lake Bonneville, Lake Lahontan, and Searles Lake, and correlative with climatic changes recorded in marine deposits. The post-Lake Chewaucan history of the basin includes Anathermal, Altithermal, and Medithermal climatic changes, as shown by a pollen profile in Upper Chewaucan Marsh. Mount Mazama pumice sand fell in the area about 6,600-6,700 years ago. Desiccation and wind work were strong in Altithermal time. In the Neopluvial (new term), corresponding to Neoglaciation in the mountains (perhaps 4,000-2,000 years ago), new lakes many tens of feet deep developed in the Summer Lake and Chewaucan Marshes-Lake Abert basins. Later, Summer Lake and Lake Abert were reduced to the very shallow, alkaline bodies of water of the present day.

Available in PDF, EPUB and Kindle. Book excerpt: Limnological research on saline lakes is practiced by a growing cadre of scientists active worldwide in a diversity of disciplines. Every three years since 1979, an international symposium on inland saline waters has served to strengthen and expand the scope of the studies. Promising areas for further research especially well suited to saline lakes include the comparative physiology of adaptation to osmotic stresses, the role of microbial and protozoan communities in nutrient dynamics and biotic interactions in ecosystems with few species. The Third International Symposium on Inland Saline Lakes was held at the University of Nairobi, Nairobi, Kenya, under the auspices of the Societas Internationalis Limnologiae (SIL). The symposium was sponsored by and received financial or other support from the U.S. National Science Foundation (International Program), United Nations Environment Program, University of California, Santa Barbara, and University of Nairobi. The proceedings occurred for three days (28-31 August, 1985) and were attended by 33 scientists from 14 countries (see list of Participants). On the day prior to the first formal session an afternoon trip to Lake Magadi and salt works was held. The tribulations of this excursion served to acquaint the participants with each other and with the realities of exploring the African bush. A three day post-congress expedition to the rift valley included visits to spectacular saline lakes such as Nakuru and Bogoria. Much of the meeting's and excursion's success is owed to the efforts of the local organizer, Dr. Stephen G.
