Download or read book Scarp Analysis of the Centennial Normal Fault Beaverhead County Montana and Fremont County Idaho written by Falene Elizabeth Petrik and published by . This book was released on 2008 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Centennial Mountains are an east-west trending mountain range in southwest Montana. The Centennial Mountains are bound on the south by the Eastern Snake River Plane, the north-trending Madison Range and fault on the east and the Centennial Valley on the north. The Centennial normal fault offsets the Centennial Mountains on the north down-dropping the Centennial Valley. Approximately 3000 meters of offset along the Centennial normal fault creates the Centennial Mountains. The present Centennial Mountains are subdivided into two stratigraphically different blocks by the Odell Creek normal fault. The eastern Centennial Mountains are interpreted as the upthrown block of the Odell Creek normal fault exposing Precambrian and Paleozoic rock along the northern face of the range. The western Centennial Mountains are interpreted as the downthrown block of the Odell Creek normal fault exposing Cretaceous and younger rocks. Both eastern and western segments of the Centennial Mountains are then offset along the range bounding Centennial normal fault. Offset along the Centennial normal fault started approximately 2.1 Ma as evidenced by the displacement of the 2.1 Ma Huckleberry Ridge tuff. It is believed that prior to the emplacement of the 2.1 Ma Huckleberry Ridge tuff, the Centennial Mountains had minimum to no surface relief. The majority of offset along the Centennial normal fault has occurred with in the late Pleistocene with estimated slip rates of 0.65-0.82 mm/yr. The late Pleistocene surface offsets along the Centennial Mountains have an average of 9.1-9.6 meters with similar offset seen along the eastern and western segments.

Download or read book Structure and Stratigraphy of the Jefferson Mountain Area Centennial Range Idaho Montana written by Clyde Leonard Murray and published by . This book was released on 1972 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Jefferson Mountain area, located at the eastern end of the Centennial Mountains in Fremont County, Idaho and Beaverhead County, Montana, is approximately 42 square miles in size. The area contains exposed metamorphic, sedimentary, and volcanic rocks ranging in age from Precambrian to Tertiary. Approximately 2,500 feet of Paleozoic and Mesozoic sedimentary rocks lie between a basal complex of Precambrian metamorphic rocks and overlying Tertiary volcanics and Quaternary alluvium. The Precambrian rocks in the area are regionally metamorphosed sedimentary rocks of the Cherry Creek Group that include hornblende schists, granite gneisses, quartzites, and dolomites. Eleven Paleozoic formations occur in the area, representing all of the Paleozoic periods except Ordovician and Silurian. The dominant rock types representing the Paleozoic are dolomites and limestones, but sandstone and shales make up a significant part of the section. The Triassic Dinwoody Formation, a silty dolomite, is the only representative of Mesozoic deposition in the thesis area. The volcanics in the area are part of the late Tertiary Yellowstone Tuff and Snake River volcanics of eastern Idaho and northwestern Wyoming. Pliocene and Early Pleistocene downwarping of the Snake River Plain resulted in block-faulting along its northeastern margin, forming the Centennial Range, a large south-tilting cuesta. The sedimentary rocks were deposited by a series of transgressions and regressions of marine water during the evolution of the Cordilleran Geosyncline. The sedimentary rocks represent the shelf facies along the eastern margin of the miogeosyncline. Oil and gas possibilities in the area are negligible. Structural and stratigraphic relationships do not indicate any type of control for the entrapment of petroleum. The economic potentiality for phosphate mining in the area is low because of the thinness of the phosphate-bearing member of the Phosphoria Formation.

Book excerpt: Normal 0 Blair Lake is a pristine, high altitude alpine mountain lake in Montana. Blair Lake is located in the Centennial Mountains Wilderness Study Area in a cirque on the Continental Divide. Springs feed the lake and the outlet flows into Hell Roaring Creek. There are three ways to access Blair Lake, the easiest is from a four-wheel drive road on the Idaho side of the Continental Divide (1½-miles), the hardest is the steep but scenic Hell Roaring Creek Trail on the Montana side of the Continental Divide (six-plus miles) and the longest hike to Blair Lake is along the Continental Divide Trail.

Download or read book Structure and Stratigraphy of the Sheep Mountain Area Centennial Range Montana Idaho written by John Lee Moran and published by . This book was released on 1971 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis area includes 44 square miles of the Centennial Range in Beaverhead County, Montana, and Clark County, Idaho. The rocks exposed in the area range in age from Precambrian to Recent and have been divided into 23 mapped units. Pre-Belt metamorphic basement rocks are overlain unconformably by 3,433 feet of Paleozoic strata included in eleven formations. These formations represent all of the periods of the Paleozoic except the Ordovician and Silurian. Nine formations represent all the periods of the Mesozoic and total approximately 3,127 feet in thickness. Cenozoic units present in the area are basalts and rhyolites, landslide debris, glacial deposits, and alluvium. The major structure of the thesis area is a fault block that is the result of uplifting and tilting of the east-west trending Centennial Range during the downwarp of the Snake River Plain in late Pliocene and Pleistocene time. No stratigraphic or structural conditions in the thesis area are favorable for the accumulation and entrapment of oil and gas. Phosphorite has been mined from the Phosphoria Formation in the area.

Available in PDF, EPUB and Kindle. Book excerpt: A Field Guide to Food & Survival Plants along Idaho's Centennial Trail was developed to introduce hikers to the abundance of wild and native plants foods along this almost 1,000-mile long trail in Idaho. For those unfamiliar with the Idaho Centennial Trail (ICT), it is a trail that starts at Murphy Hot Springs on the Idaho-Nevada border and proceeds north through the Sawtooth, Frank Church-River of No Return and the Selway-Bitterroot wilderness areas, along the Idaho/Montana border within the Bitterroot Range, and ends at the Canadian border north of Priest Lake in the Idaho Panhandle. Along the way you travel through sagebrush steppe, mountain and subalpine forests, and alpine environments. In short, a diversity of habitats and in many cases, in truly remote backcountry conditions.
