Appendix L, Bureau of Land Management Worksheets
Palen‐Ford Playa Dunes Description/Location: The proposed Palen‐Ford Playa Dunes NLCS/ ACEC would encompass the entire playa and dune system in the Chuckwalla Valley of eastern Riverside County. The area is bordered on the east by the Palen‐McCoy Wilderness and on the west by Joshua Tree National Park. Included within its boundaries are the existing Desert Lily Preserve ACEC, the Palen Dry Lake ACEC, and the Palen‐Ford Wildlife Habitat Management Area (WHMA). Nationally Significant Values: Ecological Values: The proposed unit would protect one of the major playa/dune systems of the California Desert. The area contains extensive and pristine habitat for the Mojave fringe‐toed lizard, a BLM Sensitive Species and a California State Species of Special Concern. Because the Chuckwalla Valley population occurs at the southern distributional limit for the species, protection of this population is important for the conservation of the species. The proposed unit would protect an entire dune ecosystem for this and other dune‐dwelling species, including essential habitat and ecological processes (i.e., sand source and sand transport systems). The proposed unit would also contribute to the overall linking of five currently isolated Wilderness Areas of northeastern Riverside County (i.e., Palen‐McCoy, Big Maria Mountains, Little Maria Mountains, Riverside Mountains, and Rice Valley) with each other and Joshua Tree National Park, and would protect a large, intact representation of the lower Colorado Desert. Along with the proposed Chuckwalla Chemehuevi Tortoise Linkage NLCS/ ACEC and Upper McCoy NLCS/ ACEC, this unit would provide crucial habitat connectivity for key wildlife species including the federally threatened Agassizi’s desert tortoise and the desert bighorn sheep. -

GROUND-WATER APPRAISAL OF THE BLACK ROCK OESER T AREA NORTHWESTERN NEVADA by William C. Sinclair Geologist ~··· ··. Prepared cooperatively by the Geological SUrvey, U. S. Department of Interior October, 1963 FOREWORD This reconnaissance apprais;;l of the ground~water resources of the Black Rock Desert area in northwestern Nevada is the ZOth in this series of reports. Under this program, which was initiated following legislative action • in 1960, reports on the ground-water resources of some 23 Nevada valleys have been made. The present report, entitled, "Ground-Water Appraisal of the Black Rock Desert Area, Northwe$tern Nevada", was prepared by William C. Sinclair, Geologist, U. s. Geological Survey. The Black Rock Desert area, as defined in this report, differs some~ what from the valleys discussed in previous reports. The area is very large with some 9 tributary basins adjoining the extensive playa of Black Rock Desert. The estimated combined annual recharge of all the tributary basins amounts to nearly 44,000 acre-feet, but recovery of much of this total may be difficult. Water which enters into the ground water under the central playa probably will be of poor quality for irrigation. The development of good produci1>g wells in the old lake sediments underlying the central playa appears doubtful. -
User Notes: Las Cruces, New Mexico, National Wetlands Inventory
USER NOTES : LAS CRUCES, NEW MEXICO, NATIONAL WETLANDS INVENTORY MAP Map Preparation The wetland classifications that appear on the Las Cruces NWI Base Map are in accordance with Cowardin et al .(1977) . The delineations were produced through stereoscope interpretation of 1 :110,000-scale color infrared aerial photographs taken in February, 1971, and 1 :80,000-scale bladk-and-white-aerial photographs taken in March, 1977 . The delineations were enlarged using a zoom transferscope to overlays of 1 :24,000-scale and 1 :62,500-scale . These overlays were then transferred to 1 :100,000-scale to produce the Base Map . Aerial photographs were unavailable for the western portion of the Las Cruces area 1 :62,500-scale map, the western and southern portion of the Afton area 1 :62,500-scale map, and the eastern portions of the White Sands NW, Davies Tank, Newman NW, and Newman SW area 1 :24,000-scale maps . These areas are therefore without wetland designations on the Las Cruces NWI Base Map . Extensive field checks of the delineated wetlands of the Las Cruces NWI Base Map were conducted in June, 1981 to determine the accuracy of the aerial photointerpretation and to provide qualifying descriptions of mapped wetland designations . The user of the map is cautioned that, due to the limitation of mapping primarily through aerial photointerpretation, a small percentage of wetlands may have gone unidentified . Changes in the landscape could have occurred since the time of photography, therefore some discrepancies between the map and current field conditions may exist . Any discrepancies that are encountered in the use of this map should be brought to the attention of Warren Hagenbuck, Regional Wetlands Coordinator, U . -

4.11 Mineral Resources
4. Environmental Setting, Impacts, and Mitigation Measures 4.11 Mineral Resources The purpose of this Section is to identify existing mineral resources within the Project area, analyze potential impacts to mineral resources associated with the development of the proposed Project, and identify mitigation measures that would avoid or reduce the significance of any identified impacts. Mineral resources of concern include salts, metals, industrial minerals (e.g. aggregate, sand and gravel) oil and gas, and geothermal resources that would be of value to the region and residents of the State. Thresholds of significance for the impact analysis are derived from Appendix G of the 2011 CEQA Guidelines. The operation of the Project would be managed under a plan which incorporates additional safeguards and action criteria when adverse conditions occur attributable to the Project. 4.11.1 Environmental Setting Regional Setting The Project is located within the Eastern Mojave Desert, which is characterized by broad interior desert valleys and playas intersected by isolated mountain ranges. The geologic history of the region has resulted in the deposition of economically-valuable deposits of metals and evaporite minerals. The metals include gold, silver, copper, lead, and others. These metals are typically emplaced into a variety of host rocks through the injection of hydrothermal fluids, primarily by replacement (i.e., by solution and re-precipitation), or by open-space filling (e.g., veins, breccias, pore spaces). The evaporite minerals include salts such as sodium chloride (halite, rock salt, or table salt), calcium chloride, and calcium sulfate (gypsum), along with other less common evaporite minerals. The evaporites are typically derived from the evaporation of previously saline lakes or seas, or as salts dissolved out of sediments and rocks into surface water or groundwater and are transported to lower-elevation basins, where the salts accumulate. -

NEVADA BUREAU OF LAND MANAGEMENT BLM The various resources found in the Soldier Meadows ACEC are described inside this Black Rock Desert - High Rock Canyon brochure. Please be aware of the wonderful, rare, and unique resources found in and Emigrant Trails National Conservation Area around these springs, and help ensure their continued existence by following these camping and vehicle regulations and suggestions. Soldier Meadows Area of Critical Environmental Concern Hot Spring Use BLACK ROCK DESERT Soaking in natural hot springs is a recreational activity that many people enjoy, but public land hot springs HIGH ROCK CANYON can be dangerous. Some of the hot springs in the ACEC reach temperatures over 120 degrees Fahrenheit (hot enough to burn human skin). Other hazards include biting bugs, chemical fumes, bacterial irritations, EMIGRANT TRAILS and disease. Visitors should use caution when using the areas around the springs. The BLM does not manage hot springs NATIONAL CONSERVATION AREA for human uses and recommends people to stay safe and away from natural hot pools on public lands. If you do decide to soak in the springs, please do not contaminate the water with soap or any other foreign Soldier Meadows Area of Critical substance, and avoid wearing excessive sunscreen. Environmental Concern (ACEC) Construction of new dams or other structures (such as decks, tables, benches) in and around the hot springs In 1982, 307 acres were designated as the Soldier is prohibited. Meadows Area of Critical Environmental Concern to protect special natural heritage resources. The ACEC Camping and Campfires now contains 2,077 acres to protect these rare natural and cultural resources.
