A new isostatic residual gravity map of the Tremonton 30′ x 60′ quadrangle of Utah is based on compilation of preexisting data and new data collected by the Utah and U.S. Geological Surveys. Pronounced gravity lows occur over North Bay, northwest of Brigham City, and Malad and Blue Creek Valleys, indicating significant thickness of low-density Tertiary sedimentary rocks and deposits. Gravity highs coincide with exposures of dense pre-Cenozoic rocks in the Promontory, Clarkston, and Wellsville Mountains. The highest gravity values are located in southern Curlew Valley and may be produced in part by deeper crustal density variations or crustal thinning. Steep gradients also coincide with the margins of the Promontory Mountains, Little Mountain, West Hills, and the eastern margin of the North Promontory Mountains and may define concealed basin-bounding faults.

We’re getting on the Throwback Thursday bandwagon this week. Here is a part of an 1826 world atlas that shows geography and period events, and was recently donated to the Utah DNR Library. Talk about #tbt!

The map is titled “Morse’s New Universal Atlas of the World on an Improved Plan of Alphabetical Indexes, Designed for Academies and Higher Schools” by Sidney E. Morse.

The Brian Head Quadrangle straddles the west edge of the Markagunt Plateau and is roughly centered on Brian Head Peak, at 11,307 feet (3446 m) the highest mountain in southwestern Utah. The peak, encompassing an area of great natural beauty and recreational use, is capped by volcanic rocks that erupted from calderas on the Utah-Nevada border. These volcanic rocks overlie landslide-prone local volcaniclastic strata, which in turn overlie colorful strata of the Claron Formation, centerpiece of Cedar Breaks National Monument in the southwest corner of the map area. The plateau is capped by remnants of the 20-million-year-old Markagunt Megabreccia, Utah’s largest catastrophic gravity slide.

This CD contains geographic information system (GIS) files in ESRI file geodatabase and shapefile formats. Two plates, a geologic map at 1:24,000 scale and an explanation plate, and a 38-page booklet are also included in PDF format. The latest version of Adobe Reader is required to view the PDF files.

m-241-insertGEOLOGIC MAP OF THE WHITE HOUSE QUADRANGLE, GRAND COUNTY, UTAH
Hellmut H. Doelling and Paul Kuehne

The White House quadrangle is located northeast of Arches National Park in eastern Utah. Exposed strata range from Late Jurassic Brushy Basin Member of the Morrison Formation to Late Cretaceous Mancos Shale. The quadrangle overlies the ancestral Paradox basin and is influenced by salt-related folds, including the Salt Valley anticline to the west and Cisco Dome to the east.

GEOLOGIC MAP OF THE CHARLESTON QUADRANGLE, WASATCH COUNTY, UTAH
Robert F. Biek and Mike Lowe

The Charleston quadrangle lies on the south edge of a structural and topographic saddle between the Wasatch Range and Uinta Mountains.  The quadrangle includes the southern part of Heber City and Heber Valley and the northern half of Round Valley, as well as parts of Deer Creek Reservoir and Wasatch Mountain State Park.  The quadrangle also straddles the north edge of the Charleston-Nebo thrust plate, and thus includes three distinct groups of rocks: (1) a nearly complete section of Pennsylvanian rocks of the Oquirrh Formation that comprises the Charleston thrust plate; (2) underlying, southeast-dipping Jurassic and Triassic strata below the Charleston thrust; and (3) Upper Proterozoic, Cambrian, and Mississippian strata that are exposed in a structurally complicated zone between the Charleston thrust and Deer Creek detachment faults.
A variety of late Tertiary and Quaternary deposits record the evolution of the present landscape.

This geologic map and report provide basic geologic information necessary to further evaluate geologic hazards and resources in the area, and to gain an understanding of the geology upon which this landscape developed.

GEOLOGIC MAP OF THE PROVO 7.5′ QUADRANGLE, UTAH COUNTY, UTAH
Barry J. Solomon and Michael N. Machette

The Provo 7.5′ quadrangle covers east-central Utah Valley and includes Provo, the third largest city in Utah.  Hobble Creek, the Provo River, and Spanish Fork are the primary streams in the quadrangle, flowing westward from the Wasatch Range to the Provo Bay portion of Utah Lake.  U.S. Interstate Highway 15 extends from north to south through the map area.  Included are two plates—a geologic map at 1:24,000 scale and an explanation sheet.

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-overlayThrough the use of computers and the Internet, and virtual globes such as Google Earth, we now have a way around the inherent limitations of depicting the third dimension on a standard paper geologic map. To help users gain this 3-D advantage, the UGS created an overlay of the new geologic map of the St. George 30′ x 60′ quadrangle in southwest Utah. This 3-D visualization brings the map to life, dramatically showing the relationship between geology and topography. A virtual field trip for the St. George 30′ x 60′ quadrangle, which uses placemarks to highlight selected geologic features, was also created.
