MP-08-3dmGEOLOGIC MAP OF THE WHITE CANYON–GOOD HOPE BAY AREA, GLEN CANYON NATIONAL RECREATION AREA, SAN JUAN AND GARFIELD COUNTIES, UTAH
R.E. Thaden, A.F. Trites, Jr., T.L. Finnell, and G.C. Willis

The digital database on this CD was derived from plate 1 of U.S. Geological Survey Bulletin 1125, published in 1964, with many modifications and additions by the Utah Geological Survey.  The map depicts gently folded Pennsylvanian, Permian, Triassic, and Jurassic strata exposed in the White Canyon, Good Hope Bay, Hite, and Red Canyon areas in and near Glen Canyon National Recreation Area, and includes parts of a large historical uranium mining district.

MAP 234

Map-2342GEOLOGIC MAP OF THE WEST MOUNTAIN QUADRANGLE, UTAH COUNTY, UTAH
Donald L. Clark

The West Mountain quadrangle covers West Mountain and parts of Utah and Goshen Valleys along the Interstate 15 corridor.  Improvements were made to the bedrock structure and stratigraphy, and to mapping of Quaternary surficial deposits.  The mountain consists of folded and faulted Paleozoic strata, largely of the Oquirrh Group.  The valleys are mostly covered by Quaternary deposits related to the Bonneville lake cycle, as well as by some younger deposits of Utah Lake and other surficial processes.  A large aggregate quarry is located at the south end of the mountain at Keigley.  This map is part of ongoing work by the UGS to complete a regional-scale map of the Provo 30′ x 60′ quadrangle.

MISCELLANEOUS PUBLICATION 08-1

MP-08-1PROVISIONAL GEOLOGIC MAP OF THE CHAMPLIN PEAK QUADRANGLE, JUAB AND MILLARD COUNTIES, UTAH
Janice M. Hayden, Timothy F. Lawton, and Donald L. Clark

The Champlin Peak quardrangle is located in central Utah within the eastern Basin and Range Province, and includes the northern Canyon Mountains, southeastern Gilson Mountains, and Sevier and Leamington Canyons. The map area displays structures of the Sevier fold-thrust belt, including the Canyon Range syncline, Leamington Canyon fault, Tintic Valley thrust fault, and Leamington antiform. Cretaceous conglomerate, derived from thrust sheets durin Sevier deformation, unconformably overlies Cambrian strata of the Canyon Range thrust plate. Surficial deposits include alluvial fans, fluvial sediments of the Sevier River, and deltaic sediments of Lake Bonneville. Limestone, shale, and quartzite are quarried for use in a local cement plant.

This CD contains three plates: the geologic map at 1:24,000 scale and two explanation plates, all in PDF format. Adobe Acrobat Reader is required for viewing the plates and can be downloaded at www.adobe.com.

RI-264WETLANDS IN THE FARMINGTON BAY AREA, DAVIS COUNTY, UTAH- AN EVALUATION OF THREATS POSED BY GROUND-WATER DEVELOPMENT AND DROUGHT
Charles E. Bishop, Mike Lowe, Janae Wallace, Richard L. Emerson, and J. Scott Horn

This CD contains a 36-page report of an evaluation by the Utah Geological Survey of threats to the Farmington Bay area wetlands posed by changes in climatic conditions and by increased ground-water withdrawals accompanying population growth. To evaluate the potential impacts of drought and increased development on the wetlands, we used existing data to estimate a water budget for the wetlands area. To determine the potential impacts posed by increased ground-water development and further drought, we used two regional, three-dimensional, steady-state and transient MODFLOW models for the east shore area of Great Salt Lake to evaluate water-budget changes for the wetland areas. The modeling suggests that subsurface inflow into the wetland areas would be most affected by decreased subsurface inflow due to long-term (20-year) drought conditions, but subsurface inflow would also decrease due to increased municipal and industrial well withdrawals over the same time period. Therefore, the worst-case scenario for the wetlands would be a combination of both conditions.
