Sederberg Associate Dean, College of Physical and Mathematical Sciences ABSTRACT INVESTIGATING THE MARGINS OF PLEISTOCENE LAKE DEPOSITS WITH HIGH-RESOLUTION SEISMIC REFLECTION IN PILOT VALLEY, UTAH John V. South Department of Geological Sciences Master of Science A vast area of the northeastern Great Basin of the western USA was inundated by a succession of Plio-Pleistocene lakes, including Lake Bonneville (28 ka to 12 ka). The Pilot Valley playa, located just east of the Utah-Nevada border near Wendover, Utah, within the eastern Basin and Range Province, represents an 8 to 16 km wide and ~50 km long remnant of these lakes. The playa corresponds to the upper surface of a closed basin that is delimited by two mountain ranges, which are mantled by recent alluvial fans over which the playa sediments have prograded. In order to investigate the interaction of Plio- Pleistocene lake sedimentation and alluvial fan development, high-resolution seismic reflection profiles have been acquired near the base of both the west-bounding and the east-bounding ranges. On the western side of the basin, the seismic profiles provide images of sub-horizontal playa sediments prograding over the inclined alluvial fans. The boundary between the playa and fan sediments is marked by a prominent angular unconformity. Seismic images from the eastern side of the basin reveal a markedly different structural and stratigraphic style with down-to-the-basin normal faulting of relatively shallow Paleozoic bedrock overlain by alluvial fan deposits, which are in turn on-lapped by a thin veneer of playa sediments. The results contained herein reveal for the first time the stratigraphic relationships between Quaternary pluvial sediments as a shoreline depositional facies and the adjacent bounding fan deposits. Post-stack reprocessing of lower-resolution but deeper penetration seismic data located in an analogous basin to the southwest, provides a likely context for the Pilot Valley seismic data. The new geophysical images, when integrated with available geologic mapping and limited well control, aid in constraining how deep aquifers are locally recharged from an adjacent range. The results also clearly demonstrate the strong structural asymmetry of the range and playa system, which is consistent with a classic half-graben structure. Lastly, this study demonstrates the utility of the shallow seismic reflection method as a tool to provide high-resolution sub-surface images in the geophysically challenging environment of Basin and Range geology. ACKNOWLEDGMENTS I wish to thank the many people who helped acquire the data. Specific gratitude is extended to Stephanie Ashley, Greg Carling, Nicole Cox, Eleanor McBride, Allan South, Maxwell Okure, Mary South, and Michelle Bushman.

The early settlement and development of our country occurred along our coasts and water courses. The management of our land and water resources was the catalyst which enabled us to progress from a basically rural and agrarian economy to the urban and industrialized nation we are today. Since the General Survey Act of 1824, the US Army Corps of Engineers has played a vital role in the development and management of our national water resources. At the direction of Presidents and with Congressional authorization and funding, the Corps of Engineers has planned and executed major national programs for navigation, flood control, water supply, hydroelectric power, recreation and water conservation which have been responsive to the changing needs and demands of the American people for 152 years.

  • Great Salt Lake FAQ June 2013 Natural History Museum of Utah
    Great Salt Lake FAQ June 2013 Natural History Museum of Utah What is the origin of the Great Salt Lake? o After the Lake Bonneville flood, the Great Basin gradually became warmer and drier. Lake Bonneville began to shrink due to increased evaporation. Today's Great Salt Lake is a large remnant of Lake Bonneville, and occupies the lowest depression in the Great Basin. Who discovered Great Salt Lake? o The Spanish missionary explorers Dominguez and Escalante learned of Great Salt Lake from the Native Americans in 1776, but they never actually saw it. The first white person known to have visited the lake was Jim Bridger in 1825. Other fur trappers, such as Etienne Provost, may have beaten Bridger to its shores, but there is no proof of this. The first scientific examination of the lake was undertaken in 1843 by John C. Fremont; this expedition included the legendary Kit Carson. A cross, carved into a rock near the summit of Fremont Island, reportedly by Carson, can still be seen today. Why is the Great Salt Lake salty? o Much of the salt now contained in the Great Salt Lake was originally in the water of Lake Bonneville. Even though Lake Bonneville was fairly fresh, it contained salt that concentrated as its water evaporated. A small amount of dissolved salts, leached from the soil and rocks, is deposited in Great Salt Lake every year by rivers that flow into the lake. About two million tons of dissolved salts enter the lake each year by this means. Where does the Great Salt Lake get its water, and where does the water go? o Great Salt Lake receives water from four main rivers and numerous small streams (66 percent), direct precipitation into the lake (31 percent), and from ground water (3 percent).

Sheehan, Department of Geology, Milwaukee Public Museum, 800W. Wells St., Milwaukee, Wisconsin 53233 ISBN 0-89326-122-X © 1986 Milwaukee Public Museum Abstract Two east-west transects examined in western Utah and eastern Nevada preserve Upper Ordovician-Lower Silurian lithofacies along a carbonate ramp transitional between a shelf and basin. Previous investigators have reconstructed this margin as a classic carbonate shelf with an abrupt, linear margin between shelf and slope. However, lithofacies change gradually between shelf and slope and are better explained by a carbonate ramp model. Intertidal and shallow subtidal dolomites are present to the east, with progressively deeper water limestones with increasing fine grained terrigenous content toward the west. Shelf edge reefs or shallow water carbonate margin buildups are absent. Latest Ordovician glacio-eustatic decline in sea level produced a period ofsubaerial exposure in the shallow eastern region. However, deposition continued deeper on the ramp, where shallow-water, cross laminated, massive dolomites were deposited during the glacio-eustatic regression. The carbonate ramp pattern was disrupted in the Middle or early part of the Late Llandovery, when an abrupt margin was established by listric growth faulting.
