    DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP MF-1603-A UNITED STATES GEOLOGICAL SURVEY MINERAL RESOURCE POTENTIAL OF THE COXCOMB MOUNTAINS WILDERNESS STUDY AREA (CDCA-328), SAN BERNARDINO AND RIVERSIDE COUNTIES, CALIFORNIA SUMMARY REPORT By J. P. Calzia, J. E. Kilburn, R. W. Simpson, Jr., and C. M. Alien U.S. Geological Survey and A. M. Leszcykowski and J. D. Causey U.S. Bureau of Mines STUDIES RELATED TO WILDERNESS Bureau of Land Management Wilderness Study Areas The Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976) requires the U.S. Geological Survey and the U.S. Bureau of Mines to conduct mineral surveys on certain areas to determine their mineral resource potential. Results must be made available to the public and be submitted to the President and the Congress. This report presents the results of a mineral survey of the Coxcomb Mountains Wilderness Study Area (CDCA-328), California Desert Conservation Area, Riverside and San Bernardino Counties, California. SUMMARY Geologic, geochemical, geophysical, and mineral surveys within the Coxcomb Mountains Wilderness Study Area in south­ eastern California define several areas with low to moderate potential for base and precious metals. Inferred subeconomic re­ sources of gold at the Moser mine (area Ha) are estimated at 150,000 tons averaging 1.7 ppm Au. The remainder of the study area has low potential for other mineral and energy resources including radioactive minerals and geothermal resources. Oil, gas, and coal resources are not present within the wilderness study area. INTRODUCTION Hope (1966), Greene (1968), and Calzia (1982) indicate that the wilderness study area is underlain by metaigneous and The Coxcomb Mountains Wilderness Study Area metasedimentary rocks of Jurassic and (or) older age intruded (CDCA-328) is located in the Mojave Desert of southeastern by granitic rocks of Late Jurassic to Late Cretaceous age.

  • Understanding the Source of Water for Selected Springs Within Mojave Trails National Monument, California

This evaluation mountains; bonanza spring; updates the water resource forensics of Bonanza Spring, the largest spring in the southeastern groundwater; forensics; Mojave Desert. The source of spring flow at Bonanza Spring was evaluated through an integration isotopes of published geologic maps, measured groundwater levels, water quality chemistry, and isotope data compiled from both published sources and new samples collected for water chemistry and isotopic composition. The results indicate that Bonanza Spring has a regional water source, in hydraulic communication with basin fill aquifer systems. Neighboring Lower Bonanza Spring appears to primarily be a downstream manifestation of surfacing water originally discharged from the Bonanza Spring source. Whereas other springs in the area, Hummingbird, Chuckwalla, and Teresa Springs, each appear to be locally sourced as “perched” springs. These conclusions have important implications for managing activities that have the potential to impact the desert ecosystem. Introduction above Bonanza Spring. Identification of future impacts General information and data regarding springs in the from water resource utilization becomes problematic if Mojave Desert are sparse, and many of these springs are initial baseline conditions are unknown or poorly under- not well understood.

As agreed with your office, we gathered information on areas managed by two agencies: the Department of the Interior’s Bureau of Land Management (BLN) and the Department of Agriculture’s Forest Service. Specifically, this report provides information on (1) legislative guidance and the agency policies governing wilderness study area management, (2) the various activities and uses occurring in the agencies’ study areas, (3) the ways these activities and uses affect the areas, and (4) agency actions to monitor and restrict these uses and to repair damage resulting from them. Appendixes I and II provide data on the number, acreage, and locations of wilderness study areas managed by BLM and the Forest Service, as well as data on the types of uses occurring in the areas.

  • Rice Valley Groundwater Basin Bulletin 118
    Colorado River Hydrologic Region California’s Groundwater Rice Valley Groundwater Basin Bulletin 118 Rice Valley Groundwater Basin • Groundwater Basin Number: 7-4 • County: Riverside, San Bernardino • Surface Area: 189,000 acres (295 square miles) Basin Boundaries and Hydrology This groundwater basin underlies Rice Valley in northeast Riverside and southeast San Bernardino Counties. Elevation of the valley floor ranges from about 675 feet above sea level near the center of the valley to about 1,000 feet along the outer margins. The basin is bounded by nonwater- bearing rocks of the Turtle Mountains on the north, the Little Maria and Big Maria Mountains on the south, the Arica Mountains on the west, and by the West Riverside and Riverside Mountains on the east. Low-lying alluvial drainage divides form a portion of the basin boundaries on the northwest and northeast, and the Colorado River bounds a portion of the basin on the east. Maximum elevations of the surrounding mountains range to about 2,000 feet in the Arica Mountains, about 3,000 feet in the Big Maria Mountains, and 5,866 feet at Horn Peak in the Turtle Mountains (Bishop 1963; Jennings 1967; USGS 1971a, 1971b, 1983a, 1983b, 1983c). Annual average precipitation ranges from about 3 to 5 inches. Surface runoff from the mountains drains towards the center of the valley, except in the eastern part of the valley, where Big Wash drains to the Colorado River (USGS 1971a, 1971b, 1983a, 1983b, 1983c). Hydrogeologic Information Water Bearing Formations Alluvium is the water-bearing material that forms the basin and includes unconsolidated Holocene age deposits and underlying unconsolidated to semi-consolidated Pleistocene deposits (DWR 1954, 1963).

  • Appendix D Building Descriptions and Climate Zones
    Appendix D Building Descriptions and Climate Zones APPENDIX D: Building Descriptions The purpose of the Building Descriptions is to assist the user in selecting an appropriate type of building when using the Air Conditioning estimating tools. The selected building type should be the one that most closely matches the actual project. These summaries provide the user with the inputs for the typical buildings. Minor variations from these inputs will occur based on differences in building vintage and climate zone. The Building Descriptions are referenced from the 2004-2005 Database for Energy Efficiency Resources (DEER) Update Study. It should be noted that the user is required to provide certain inputs for the user’s specific building (e.g. actual conditioned area, city, operating hours, economy cycle, new AC system and new AC system efficiency). The remaining inputs are approximations of the building and are deemed acceptable to the user. If none of the typical building models are determined to be a fair approximation then the user has the option to use the Custom Building approach. The Custom Building option instructs the user how to initiate the Engage Software. The Engage Software is a stand-alone, DOE2 based modeling program.
