CEDAR MOUNTAIN AND DAKOTA FORMATIONS AROUND DINOSAUR NATIONAL MONUMENT—EVIDENCE OF THE FIRST INCURSION OF THE CRETACEOUS WESTERN INTERIOR SEAWAY INTO UTAH

 

 

 

 

 

 

 

 

 

 

 

by Douglas A. Sprinkel, Scott K. Madsen, James I. Kirkland, Gerald L. Waanders, and Gary J. Hunt

This 20-page report describes the stratigraphy of the Cedar Mountain and Dakota Formations in and around Dinosaur National Monument in northeast Utah and includes new palynology and radiometric age data. The contact between these formations is unconformable in which the Dakota Formation has incised into the underlying Cedar Mountain Formation. Locally, the Dakota includes a basal marine mudstone and shale until that contains late Albian dinoflagellate cysts, which represents peak sea level during the Kiowa-Skull Creek depositional cycle and indicates the first marine incursion of the Cretaceous Western Interior Seaway into Utah.

GEOLOGIC MAP OF THE OPHIR QUADRANGLE, TOOELE COUNTY, UTAH

 

 

 

 

 

 

 

 

 

 

 

 

by Stefan M. Kirby

This map represents the geology of the Ophir quadrangle at 1:24,000 scale. The Ophir quadrangle, in southeastern Tooele County, Utah, includes part of the Oquirrh Mountains and an adjoining part of Rush Valley. Quaternary unconsolidated deposits cover the southwestern two-thirds of the quadrangle, and are broadly divisible into alluvial and lacustrine deposits that are separated by the highstand shoreline of Lake Bonneville. A series of down-to-the-southwest normal faults cut unconsolidated deposits and bedrock parallel to the margin of the Oquirrh Mountains and define the southern Oquirrh Mountain fault zone. Bedrock includes Pennsylvanian-to Cambrian-age sedimentary rocks exposed in the Oquirrh Mountains, which are broadly folded across the north-northwest tranding Ophir anticline. Igneous rocks include rhyolite dikes and other intrusions, and at least two magic dikes that cut across sedimentary bedding and some faults at high angles. This CD includes a 13-page report and two plates.

PRELIMINARY GEOLOGIC MAP OF THE GLEN CANYON DAM AREA, GLEN CANYON NATIONAL RECREATION AREA, COCONINO COUNTY, ARIZONA, AND KANE AND SAN JUAN COUNTIES, UTAH

 

 

 

 

 

 

 

 

 

 

 

by Grant C. Willis

This CD contains plot files of a geologic map of the Glen Canyon Dam area of southern Utah and northern Arizona (provided as two plates-east and west parts), and is one of several maps recently completed by the Utah Geological Survey that provide complete geologic map coverage of Lake Powell and Glen Canyon National Recreation Area. Glen Canyon Dam, completed in 1964, is anchored in Jurassic Navajo Sandstone, the oldest formation exposed in the map area. Jurassic and Cretaceous strata are cut by a few small faults and warped by broad shallow folds. Surficial deposits consist of extensive river and stream terrace gravel, eolian sand, and minor alluvium and talus. The map is based on new field mapping and aerial photograph interpretation and is provided as two plates in PDF format with a 12-page explanatory booklet that describes map units.

PRELIMINARY LANDSLIDE INVENTORY MAP OF THE 2012 SEELEY FIRE AREA, CARBON AND EMERY COUNTIES, UTAH

 

 

 

 

 

 

 

 

 

 

 

by Greg N. McDonald and Richard E. Giraud

This map presents a landslide inventory for the 2012 Seeley fire area, Carbon and Emery counties, Utah, at a scale of 1:24,000. The purposes of the map and accompanying geodatabase are to show and characterize landslides and debris-flow areas and provide information useful for managing landslide-related issues within the burn area. Spatial and tabular data for each landslide are stored in the geodatabase and linked to the inventory map. Landslide information in the geodatabase includes: area, material type, movement type, landslide deposit name, landslide source name, movement activity, thickness, movement direction, approximate movement dates, geologic unit associated with landsliding, confidence in mapped boundaries, mapper, peer reviewer, and general comments.

AQUIFER PARAMETER ESTIMATION FROM AQUIFER TESTS AND SPECIFIC-CAPACITY DATA IN CEDAR VALLEY AND THE CEDAR PASS AREA, UTAH COUNTY, UTAH

 

 

 

 

 

 

 

 

 

 

by J. Lucy Jordan

This 62-page report details aquifer parameter estimation in and near Cedar Valley, west of Utah Lake and the Lake Mountains, in Utah County, Utah. The UGS conducted five aquifer tests on the two most important aquifers in the study area—the principal basin-fill aquifer and the fractured-bedrock aquifer. The aquifer tests on bedrock wells are of particular interest because of the importance of the bedrock groundwater resource in the Cedar Pass area, where surface water and shallow groundwater are scarce. The tests reveal valuable information about the interface between the basin- fill and bedrock aquifers, a key path for groundwater discharge from the Cedar Valley groundwater basin. Aquifer test analysis was combined with re-analysis of existing aquifer-test data and specific- capacity data from well logs to determine a range of hydraulic conductivity, transmissivity, and storativity for the aquifers. Anisotropy was identified in both the basin-fill and bedrock aquifers, and the bedrock aquifer was found to be bounded by semi-permeable aquifer boundaries; a wedge of Tertiary volcanic rock and buried faults are the likely barriers to groundwater flow near Cedar Pass.

GEOLOGIC MAP OF THE SHORT CANYON QUADRANGLE, EMERY COUNTY, UTAH

 

 

 

 

 

 

 

 

 

 

by Hellmut H. Doelling and Paul A. Kuehne

The Short Canyon quadrangle in Emery County, central Utah, has some world-class examples of Utah’s spectacular geology. Driving through the quadrangle on the Moore Road takes you from the Jurassic Carmel Formation through about 100 million years or 3700 feet (1200 m) of rock into the Cretaceous Mancos Shale. Many species of dinosaur have been discovered in the Cretaceous Cedar Mountain Formation, which is beautifully exposed here. The Short Canyon Member of the Cedar Mountain Formation was mapped and newly described in the quadrangle. Mineral resources from the area include gypsum, coal, and chalcedony.

GIS files are provided in an ESRI file geo database and as ESRI shapefiles. Also included is a 13-
page booklet and two plates.

GEOLOGICAL CHARACTERIZATION OF THE BIRDS NEST AQUIFER, UINTA BASIN, UTAH: ASSESSMENT OF THE AQUIFER’S POTENTIAL AS A SALINE WATER DISPOSAL ZONE

 

 

 

 

 

 

 

 

 

 

by Michael D. Vanden Berg, Danielle R. Lehle, Stephanie M. Carney, and Craig D. Morgan

As petroleum production increases in the Uinta Basin, Utah, operators are pressed to establish
suitable saline water disposal plans. Several natural gas operators have identified the Birds Nest aquifer in central Uintah County as a possible large-scale, saline water disposal zone; however, disposal into this aquifer poses unique challenges and risks. The Birds Nest aquifer formed from the dissolution of saline minerals within a saline zone in the upper Green River Formation’s Parachute Creek Member. Through the examination of core, outcrop, and geophysical logs, we determined that the aquifer is separated into an upper zone, covering about 410 square miles with an average thickness of 79 feet, and a more extensive lower zone, covering about 719 square miles with an average thickness of 84 feet. The fact that the Birds Nest aquifer lies within the Uinta Basin’s oil shale horizon raises questions as to how large-scale, saline water disposal into this zone might impact potential future oil shale development.

repost from Utah Division of Wildlife Resources

Sandy—Kids can catch fish, learn about predators and find out how to ride an ATV safely at this year’s DNR Youth Outdoor Sports Fair.

The sports fair is part of the upcoming International Sportsmen’s Exposition.

The expo will be held March 18 to March 21,2010 at the South Towne Exposition Center, 9575 S. State in Sandy. The cost to attend the exposition, which includes the youth fair, is $12 for adults. Kids 15 years of age or younger can attend for free.

The Youth Outdoor Sports Fair will be held at the south end of the exposition center. Six divisions will host activities: Forestry, Fire and State Lands; Oil, Gas and Mining; Parks and Recreation; the Utah Geological Survey; Water Resources; and Wildlife Resources.

More than 20 activities await children who attend the fair. Among the things kids can do:

  • Catch trout in a fishing pond.
  • Make a survival kit.
  • Tie fishing flies.
  • See how big they are compared to a deer, an elk or a moose!
  • Learn how to stay safe in black bear country.
  • Learn about dinosaurs.
  • Learn about Utah’s rocks.
  • Learn how to boat safely.
  • Learn how to conserve water.
  • Learn about a future career with the DNR.

“We want to get children excited about the outdoors,” says Mike Styler, executive director of the Department of Natural Resources. “We also want to teach them skills that will make their next trip into the outdoors safe and enjoyable.”
