Ostrom and published by Yale University Press. This book was released on 2020-03-17 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fiftieth anniversary edition of a landmark publication showcasing prehistoric North American landscapes and ecosystems, from a celebrated paleontologist at Yale University's Peabody Museum The fiftieth anniversary edition of John H. Ostrom's Stratigraphy and Paleontology of the Cloverly Formation revisits his groundbreaking work pinpointing the age of the continental sequence of the Bighorn Basin area in Wyoming and Montana. The Cloverly Formation is important for understanding the development of North American terrestrial landscapes and prehistoric ecosystems, and current investigations are reinterpreting the age of the Formation with new evidence and data. The reissue of Ostrom's original benchmark research offers contemporary relevance for researchers and students today.

Book excerpt: Sponsored by a grant from the National Science Foundation to the Denver Museum of Natural History. Ever wondered what the ground below you was like millions of years ago? Merging paleontology, geology, and artistry, Ancient Wyoming illustrates scenes from the distant past and provides fascinating details on the flora and fauna of the past 300 million years. The book provides a unique look at Wyoming, both as it is today and as it was throughout ancient history—at times a vast ocean, a lush rain forest, and a mountain prairie.

Bureau Of Land Management and published by Forgotten Books. This book was released on 2018-02-07 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Land Planning and Classification Report of the Public Domain Lands in the Bighorn Basin, Montana and Wyoming: A Missouri River Basin Investigation Bighorn Basin is a resource-rich segment of the Missouri River System, replete with extensive irrigated areas of fertile cropland, desert grazing lands, cattle and sheep ranches, tower ing mountains, forests, oil and gas wells and refineries, eight thriving cities, a bustling tourist traffic, and deposits of benton ite, sulphur, gypsum, phosphate, and other minerals. The study area includes the drainage of the Bighorn River from Boysen Dam, at the head of Wind River Canyon in Wyoming, to the Yellowtail dam site, at the mouth of Bighorn Canyon in Montana. The upper portion of the drainage of the Clarks Fork of the Yellowstone lo cated west of the Basin has been included in the area because it comprises a physical and economic land group. The area is 130 miles long by 153 miles in width, and covers 13, 510 square miles. The Custer National Forest is on the mountains in the north western and northeastern portion of the area in Montana. The Big Horn National Forest is on the eastern portion of the area and the Shoshone National Forest is on the west in Wyoming. Wind River Indian Reservation is in the southwestern part of the Basin and the Crow Reservation is in the Pryor Mountains on the north east in Montana. The National Forests and Indian reservations are located on mountainous lands and were not examined. They cover an area of 2, 502, 864 acres. Gross size of the Basin area is 8, 646, 555 acres, with a net area of 6, 143, 691 acres, which has been examined as set forth in this report. This net area is private, state, and public domain land located outside the National Forests and Indian lands. Political subdivisions included within the area are Big Horn, Hot Springs, Park, and Washakie Counties in Wyoming, and parts of Carbon, Big Horn, and Park Counties in Montana. Important cities are Basin, Cody, Greybull, Lovell, Powell, Thermopolis, and Worland, Wyoming, and Bridger, Montana. The Bureau of Reclamation units in the area include the pioneer Shoshone project with Buffalo Bill Dam and power plant, and the Shoshone extension unit.

Download or read book Uplift of the Bighorn Mountains Wyoming and Montana written by C. E. Whipkey and published by . This book was released on 1991 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluvial and lacustrine-dominated clastic sedimentary rocks as thick as 1,800 m (6,000 ft) comprise the Paleocene Fort Union Formation and the Eocene Wasatch Formation of the western Powder River Basin in northeastern Wyoming and southeastern Montana. The systematic mineralogy of 45 samples of channel-fill sandstone from this sequence reflects the uplift and erosion of the Bighorn Mountains. Samples were collected to study vertical changes in the mineralogy of lower Tertiary sandstones adjacent to the Bighorn Mountains, lateral variations in the composition of the upper Paleocene Tongue River Member of the Fort Union Formation along the eastern front of the mountains, and variations in the composition of equivalent upper Paleocene sandstones of the central and western parts of the basin. Vertical changes in the mineralogy of a succession of Paleocene and Eocene sandstone units adjacent to the Bighorn Mountains most likely were produced by uplift and sequential erosion of the rocks that formerly overlaid the mountains. Uplift probably began in the middle Paleocene, during deposition of the Lebo Member of the Fort Union Formation, and continued into the Eocene. Differences in the mineralogy of the sandstone units along the western edge of the Powder River Basin that correspond to differences in the rock types now exposed along the crest of the Bighorn Mountains suggest that much of the erosional degradation of the Bighorn Mountains occurred during an early Tertiary tectonic episode. Lateral changes in the suite of unstable detrital grains within the Tongue River Member are compatible with facies and paleotransport studies that indicate a substantial eastward flux of detritus of early Tertiary age from the Bighorn Mountains into the central Powder River Basin.
