Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a preliminary evaluation of the East Bear Lake (EBF) and West Bear Lake (WBF) fault zones, which bound the east and west sides, respectively, of the Bear Lake Valley. The Bear Lake Valley straddles the Utah/Idaho border northeast of Logan, Utah. The results of this study show that both the EBF and the WBF have experienced surface-faulting earthquakes in the recent geologic past and therefore represent an ongoing seismic hazard to northeastern Utah and southeastern Idaho.
Download or read book Paleoenvironments of Bear Lake Utah and Idaho and Its Catchment written by Joseph G. Rosenbaum and published by Geological Society of America. This book was released on 2009 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bear Lake is located 100 km northeast of Salt Lake City and lies along the course of the Bear River, the largest river in the Great Basin. The lake, which is one of the oldest extant lakes in North America, occupies a tectonically active half-graben and contains hundreds of meters of Quaternary sediment. This volume is the culmination of more than a decade of coordinated investigations aimed at a holistic understanding of this long-lived alkaline lake in the semiarid western United States. Its 14 chapters, with 20 contributing authors, contain geological, mineralogical, geochemical, paleontological, and limnological studies extending from the drainage basin to the depocenter. The studies span both modern and paleoenvironments, including a 120-m-long sediment core that captures a continuous record of the last two glacial-interglacial cycles.

Available in PDF, EPUB and Kindle. Book excerpt: Lake Bonneville: A Scientific Update showcases new information and interpretations about this important lake in the North American Great Basin, presenting a relatively complete summary of the evolving scientific ideas about the Pleistocene lake. A comprehensive book on Lake Bonneville has not been published since the masterpiece of G.K. Gilbert in 1890. Because of Gilbert’s work, Lake Bonneville has been the starting point for many studies of Quaternary paleolakes in many places throughout the world. Numerous journal articles, and a few books on specialized topics related to Lake Bonneville, have been published since the late 1800s, but here the editors compile the important data and perspectives of the early 21st century into a book that will be an essential reference for future generations. Scientific research on Lake Bonneville is vibrant today and will continue into the future. Makes the widespread and detailed literature on this well-known Pleistocene body of water accessible Gives expositions of the many famous and iconic landforms and deposits Contains over 300 illustrations, most in full color Contains chapters on many important topics, including stratigraphy, sedimentology, hydrology, geomorphology, geochronology, isostasy, geophysics, geochemistry, vegetation history, pollen, fishes, mammals, mountain glaciation, prehistoric humans, paleoclimate, remote sensing, and geoantiquities in the Bonneville basin
Download or read book Why is Bear Lake So Blue written by Jim Davis and published by Utah Geological Survey. This book was released on 2011-03 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to its splendor, Bear Lake is a scientific wonder. Over the past few decades, Bear Lake has been intensely studied because it is one of the oldest lakes in North America, has not dried up during extended warm and dry climates, and is in an area sensitive to changes in regional climate pattterns. Therefore, Bear Lake research helps us to understand past climates and environments of this area. For the first time, a non-technical publication - this brochure - has been published to help the general public understand the wonders of Bear Lake.

Download or read book Quaternary Tectonics of Utah with Emphasis on Earthquake hazard Characterization written by Suzanne Hecker and published by Utah Geological Survey. This book was released on 1993-01-13 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report consolidates and synthesizes information on Quaternary faulting, folding, and volcanism in Utah and characterizes recent tectonic activity throughout the state. The primary purpose is to provide a comprehensive reference on fault-specific seismic sources and surface rupture to facilitate the evaluation of earthquake hazards in Utah. Two 1:500,000-scale maps show Quaternary tectonic features categorized according to probable ages of most recent surface deformation and ages of volcanic rocks. Two appendix tables summarize significant data on the activity of mapped features, including ages of surface displacements and volcanism, slip rates, recurrence intervals, displacement amounts, and lengths of surface ruptures. Good age control and quantitative activity data are available for relatively few tectonic features in Utah and detailed work is needed in many areas of the state. 157 pages + 2 plates

This book was released on 2005-06-30 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of the Utah Quaternary Fault Parameters Working Group (hereafter referred to as the Working Group) review and evaluation of Utah’s Quaternary fault paleoseismic-trenching data. The purpose of the review was to (1) critically evaluate the accuracy and completeness of the paleoseismictrenching data, particularly regarding earthquake timing and displacement, (2) where the data permit, assign consensus, preferred recurrence-interval (RI) and vertical slip-rate (VSR) estimates with appropriate confidence limits to the faults/fault sections under review, and (3) identify critical gaps in the paleoseismic data and recommend where and what kinds of additional paleoseismic studies should be performed to ensure that Utah’s earthquake hazard is adequately documented and understood. It is important to note that, with the exception of the Great Salt Lake fault zone, the Working Group’s review was limited to faults/fault sections having paleoseismic-trenching data. Most Quaternary faults/fault sections in Utah have not been trenched, but many have RI and VSR estimates based on tectonic geomorphology or other non-trench-derived studies. Black and others compiled the RI and VSR data for Utah’s Quaternary faults, both those with and without trenches.

Download or read book Surficial Deposits and Geologic History Northern Bear Lake Valley Idaho written by George C. Robertson and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed geologic mapping and subsurface study of late Pleistocene and Holocene sediments in northern Bear Lake Valley show at least four episodes of deposition of fluvial, marsh, bay, and lacustrine sediments. from oldest to youngest, these are the Ovid, Liberty, Wardboro, and Lifton episodes. These episodes are substantially different than those proposed by previous investigators. The informal term Bear Lake Formation is formally redefined here as the Bear Lake Group, and includes the newly defined Ovid Formation, Liberty Formation, lanark Formation, and Rainb= Gravel. The overlying Wardboro Loess, also defined here, provides a probably age of 11,000 to 8,000 years B. P. for widespread post-Wisconsinan deposition of loess in northern Utah and southern Idaho. The Ovid Episode began prior to 27,400 years B. P., d=ing a warm, dry, climatic interval. Sediments deposited during the early part of the Ovid Episode include marsh and bay deposits of the l=er part of the Ovid Formation in northern Bear Lake Valley, probably similar deposits of the lCN~er part of the lanark Formation west of the Bloomington Scarp (on the west side of Bear Lake Valley), and marshy deposits beneath Bear Lake in southern Bear Lake Valley. West-sloping pediments at the north end of Bear Lake Valley, between Bennington and Georgetown, Idaho, and old alluvial fans, also may have formed at this time. The northern outlet of the valley was near 5990 feet at this time. Downfaulting along the Bear L3ke fault zone on the east side of Bear L3ke Valley, and prol:able eastward tilting affected the central valley during the Ovid Episode. At this time, deposition of deep-water carbonates, beneath Bear L3ke, prol:ably began in southern Bear L3ke Valley. Later, cooler- and Jl'Oister clirratic conditions of a Late Pleistocene glacial interval (Pinedale?) resulted in a shall& extension of this lake into northern Bear L3ke Valley during the Liberty Episode. Progradational, shallow-water sand deposits of the Liberty Formation show that Bear Lake attained its most recent maximum areal extent at this time. Simultaneous deposition of the Rainbow Gravel at the entrance of the Bear River into the valley, near Dingle, Idaho, and of the sandy, deltaic upper part of the Lanark Formation along the west side of the valley, reflected the increased addition of sediments, probably due to glaciation and higher stream discharges. The valley outlet was at an altitude near 5945 feet. Downcutting of the valley outlet and waning moist climatic conditions led to exposure of lake beds, increased effectiveness of the wind, and deposition of the Wardboro Loess during the Wardboro Episode. This loess prol:ably is correlative with the Niter Loess in Thatcher Basin (Gem and Gentile valleys, Idaho). It is slightly more than 8,000 C14 years old, and probably less than 11,000 year old. Recurrent faulting along the east margin (Bear Lake fault zone) and west margin (Bloomington Scarp) of the valley at the onset of the Lifton Episode led to a brief re- expansion of Bear Lake, and then a recession southward to its present position near 5923 feet. During this time, a series of beach ridges, successively younger southward, and undifferentiated sediments of marsh, bay, and stream origin, formed in northern Bear Lake Valley. The present valley outlet is near 5873 feet.
