  • The Influence of Hydrology and Climate on the Isotope Geochemistry
    Sedimentology (2007) doi: 10.1111/j.1365-3091.2007.00932.x The influence of hydrology and climate on the isotope geochemistry of playa carbonates: a study from Pilot Valley, NV, USA CYNTHIA M. LIUTKUS* and JAMES D. WRIGHT *Department of Geology, Appalachian State University, ASU Box 32067, Boone, NC 28608, USA (E-mail: [email protected]) Department of Geological Sciences, Rutgers University, 610 Taylor Road, Piscataway, NJ 08854, USA ABSTRACT Carbonates often accompany lake and lake-margin deposits in both modern and ancient geological settings. If these carbonates are formed in standing water, their stable isotope values reflect the aquatic chemistry at the time of precipitation and may provide a proxy for determining regional hydrologic conditions. Carbonate rhizoliths and water samples were collected from a playa lake in eastern Nevada. Pilot Valley (43°N) is a closed-basin, remnant playa from the Quaternary desiccation of palaeo-Lake Bonneville. Water is added to the playa margin by free convection of dense brines to the east and forced convection of freshwater off the alluvial fan to the west. Both freshwater and saline springs dot the playa margin at the base of an alluvial fan. Water samples collected from seven springs show a range from )16 to )0Æ2& (Vienna Standard Mean Ocean Water), and are consistent with published values. The 18 ) ) d Ocalcite values from rhizolith samples range from 18Æ3to 6Æ7& (Vienna Pee Dee Belemnite), and the average is )12& V-PDB (1 ) r SD 2&). With the 18 exception of samples from Little Salt Spring, the range in the d Ocalcite values collected from the rhizoliths confirms that they form in equilibrium with ambient water conditions on the playa.

  • Curlew National Grassland Monitoring Report
    Curlew National Grassland Land and Resource Management Plan Monitoring Report The 2002 Curlew National Grassland Plan (Plan) identified goals and objectives for land management over the next decade (pp. 3-1 to 4-11). Goals describe desired conditions for the future and they are typically general without a specific timeframe for achieving them. An objective is a quantifiable statement of progress in meeting goals, and therefore measure progress towards implementing the Plan. The Plan identified objectives for the management of the Curlew National Grassland (Grassland) and established specific time frames to meet each objective (Plan, pp. 5-1 and 5-2). The progress made toward meeting each objective is displayed in Table A of this Monitoring Report (pages 1-12). This evaluation has been made by employees of the Caribou-Targhee National Forest responsible for the management of the Grassland (Forest). These results are used to help design the annual program of work for each resource group. The following table lists the objectives and the actions we have taken towards meeting the objectives in the Plan. Table A: Objectives OBJECTIVE WHEN?

Although no p'otash has been pro­ duced from these brines in the last few years, a continued interest in the area has been shown by a large number of filings, in different parts of the desert, under the potash law of October 2, 1917 (40 Stat. 297), and the regulations issued under that law by the Department of the Interior on March 21, 1918, in Circular 594 (46 L.

  • Statement of Tom Fulton Deputy Assistant Secretary
    Statement of Tom Fulton Deputy Assistant Secretary– Land and Minerals Management Department of the Interior House Resources Committee Subcommittee on National Parks, Recreation and Public Lands on H.R. 2488, Pilot Range Wilderness July 26, 2001 Thank you for the opportunity to testify regarding H.R. 2488. The Department appreciates Chairman Hansen's efforts in continuing to address wilderness in Utah. The Department of the Interior supports H.R. 2488, which designates over 37,000 acres of land in western Utah as wilderness. We would like the opportunity to work with the Committee on clarifying and technical amendments to the legislation before the Committee completes its consideration of this bill. The proposed Pilot Range Wilderness Area lies in Box Elder County, Utah. Rising to over 10,761 feet, Pilot Peak served as a beacon for travelers headed to California in the 1840s and, for some, a beacon of false hope. Travelers who had completed the hot, dry trek across the Great Salt Lake Desert found water in the springs along the eastern base of the range. Located approximately 115 miles northwest of Salt Lake City, along the Utah and Nevada state line, the Pilots are a north-south trending mountain range, with canyons draining east to a large alkali flat, and west to a broad valley that extends into Nevada. The rugged terrain (ridges, side canyons and valley bottoms) meets the requirements of the Wilderness Act. Diverse vegetation complements the topography by providing screening from human activity. Opportunities for hunting, camping, hiking, and photography are outstanding. Horseback riding and pack trips are abundant throughout the area.

Utah Well Hydrographs . • . 11 ii INTRODUCTION HISTORY Curlew Valley is an agricultural community that began development approximately at the turn of the century. Surface water was originally developed, while extensive ground water development began in the 1950's. Both surface and ground water are now used for irrigation. In the 1970's permit applications for further development of ground water created concern of possible overdraft conditions within the Idaho side of the valley. The overdraft conditions could have possibly impacted a wildlife refuge in Utah (Locomotive Springs) and created non-economic pumping conditions in Idaho. Based on these possibilities, the Idaho Department of Water Resources (IDWR) conducted an investigation. The February, 1976, open file report, no author, could not definitively address all possibilities due to lack of data, but did recommend that the valley be designated as a "Critical Ground Water Area" (CGWA). Basis for this was that, "existing licensed and permit rights can potentially develop the portion of natural recharge as yet undeveloped" (IDWR, 1976).

  • Pilot Creek Valley (Updated 2014)
    Site Description Pilot Creek Valley (Updated 2014) Geologic setting: The Pilot Creek Valley is located near the border of Nevada and Utah approximately 30 kilometers northwest of West Wendover, Nevada. Pilot Creek Valley also lies between the Toano Range towards the west and the Pilot Range towards the east. The Pilot Range is composed of slate, argillite, phyllite, metasiltstone, quartzite, and conglomerate and is exposed throughout the range (Woodward, 1967). The Pilot Range is a north trending mountain range located west of the Nevada-Utah border. The range is composed of metamorphosed Cambrian and Proterozoic strata with Mesozoic igneous rocks that are overlain by Quaternary sedimentary rocks and other unconsolidated material. Multiple faults and folds are prominent throughout the range including bedding plane faults, low angle faults, and high angle Tertiary strike-slip and normal faults. These normal faults are range bounding faults parallel to the range fronts (Miller and Lush, 1981). The southern Toano range is composed primarily of Cambrian and Ordovician carbonate and shale units that have been deformed into northeast plunging folds. Metamorphism has occurred in this region resulting in bleached and marbleized limestone with shale units being converted to slate and phyllite with some minor muscovite schist. These units make up the Silver Zone terrane which was intruded by the Middle Jurassic Silver Zone Pass pluton (Ketner et al, 1998). Geothermal features: A warm spring on the western side of Pilot Creek Valley (T36N, R68E, Sec. 34?) was sampled by NBMG in 2008. The spring had been converted into a tractor tire cattle trough. Samplers reported “Water flows upward through a pipe, with algae and white salt deposits visible inside the tube.
