    DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP I-1830 U.S. GEOLOGICAL SURVEY GEOLOGIC MAP OF THE LYNNDAL 30- BY 60-MINUTE QUADRANGLE, WEST-CENTRAL UTAH By Earl H. Pampeyan INTRODUCTION techniques, and topographic base maps will benefit future interpretations. The Lynndyl 30- by 60-minute 1: 100,000-scale Map units selected for use on this map correspond as quadrangle is located in west-central Utah at the eastern nearly as possible to a division of geologic periods into edge of the Great Basin (fig. 1). The Sevier River, which epochs. The map-unit boundaries, in most cases, match drains part of the western Colorado Plateaus province, epoch boundaries, but where a formation boundary flows through the southeast corner of the quadrangle and straddles a time boundary the formation is arbitrarily terminates at Sevier Lake. The rocks and sediments included tn one or the other adjacent unit, and owing to exposed in the quadrangle represent a fairly complete map scale and thickness of map units, the map pattern is sequence ranging in age from Middle Proterozoic to not noticeably different than if the formation had been Holocene excluding most of the Mesozoic, which is included in the other adjacent map unit. An attempt at present to the east in the Colorado Plateaus. The consistency in usage is made, but differences in mapping presence of major ore deposits in the East Tintic style and interpretation in the source materials Mountains stimulated geologic interest in this region, and inadvertantly may cause some misidentifications or early stratigraphic work was concentrated around the misassignments.

    APRIL 2002 RIFE ET AL. 921 Mechanisms for Diurnal Boundary Layer Circulations in the Great Basin Desert DARAN L. RIFE National Center for Atmospheric Research, Boulder, Colorado* THOMAS T. W ARNER National Center for Atmospheric Research,* and Program in Atmospheric and Oceanic Sciences, University of Colorado, Boulder, Colorado FEI CHEN National Center for Atmospheric Research, Boulder, Colorado* ELFORD G. ASTLING U.S. Army West Desert Test Center, Dugway Proving Ground, Dugway, Utah (Manuscript received 6 April 2001, in ®nal form 6 September 2001) ABSTRACT The purpose of this observation- and model-based study of the Great Basin Desert boundary layer is to illustrate the variety of locally forced circulations that can affect such an area during a diurnal cycle. The area of the Great Basin Desert (or Great Salt Lake Desert) that is studied is located to the southwest of Salt Lake City, Utah. It is characteristic of the arid ``basin and range'' province of North America in that it contains complex terrain, varied vegetation and substrates, and high water tables associated with salt-encrusted basin ¯ats (playas). The study area is especially well instrumented with surface meteorological stations operated by the U.S. Army's West Desert Test Center and a collection of cooperating mesonets in northeastern Utah. The study period was chosen based on the availability of special radiosonde data in this area. One of the processes that is documented here that is unique to desert environments is the salt breeze that forms around the edge of playas as a result of differential heating. The data and model solution depict the diurnal cycle of the salt breeze, wherein there is on-playa ¯ow at night and off-playa ¯ow during daylight.

  • OSIRIS-Rex Environmental Assessment / FONSI
    National Aeronautics and Space Administration • Final Environmental Assessment for the Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer Mission March 2013 www.nasa.gov FINAL ENVIRONMENTAL ASSESSMENT (EA) FOR THE ORIGINS, SPECTRAL INTERPRETATION, RESOURCE IDENTIFICATION, SECURITY - REGOLITH EXPLORER (OSIRIS-REX) MISSION TITLE PAGE Lead Agency: National Aeronautics and Space Administration (NASA) Proposed Action: Preparing for and implementing the Origins, Spectral Interpretation, Resource Identification, Security - Regolith Explorer (OSIRIS-REx) mission, including the launch from Cape Canaveral Air Force Station (CCAFS), Florida, in September 2016; sample return capsule recovery at the Utah Test and Training Range (UTTR) in Tooele County, Utah, in September 2023; and curation of samples at the Johnson Space Center (JSC), Houston, Texas. For Further Information, Contact: Lizabeth Montgomery, GSFC NEPA Program Manager, NASA Goddard Space Flight Center, Code 250, Building 28, Room N150F, 8800 Greenbelt Road, Greenbelt, MD 20771; Phone: (301) 286-0469; [email protected] Date: March 2013 Abstract: The OSIRIS-REx mission would be the first U.S. mission to carry samples from an asteroid back to Earth. Asteroids are leftovers formed from the cloud of gas and dust that collapsed to form our Sun and the planets about 4.5 billion years ago. As such, they contain the original material from the solar nebula, which can inform us about the conditions during our solar system’s birth. The mission would help us investigate planet formation and the origin of life, as well as aid our understanding of asteroids that can impact Earth. NASA proposes to launch the OSIRIS-REx spacecraft from CCAFS, Florida, in September 2016 on an Atlas V class launch vehicle.

  • 3.7 Water Resources, Including Culinary and Municipal Water Systems, Surface Water, and Groundwater
    Uinta National Forest Oil and Gas Leasing Draft Environmental Impact Statement 3.7 Water Resources, Including Culinary and Municipal Water Systems, Surface Water, and Groundwater 3.7.1 Overview Water Quality Water quality in the UNF is influenced by several factors including geology, soils, vegetation, and human activities. Low dissolved oxygen, high phosphorous loads, and sedimentation are the prevailing water quality problems in the UNF. In general, water quality issues in the UNF are closely related to human activities that cause surface disturbance such as road use, grazing, and recreational use. Table 3.21 is a summary of water quality issues by RFOGD. Table 3.21. Summary of water quality issues for RFOGDs with oil and gas potential.
