  • Chapter 2 Management Plan
    Chapter 2 Management Plan Mahogany Canyon in the High Rock Canyon Wilderness 2.1 INTRODUCTION This chapter contains objectives and decisions for managing the natural, physical and cultural resources described in the Act and those located in parts of the planning area not included in the National Conservation Area or designated Wilderness Areas. Background information is provided for each of these resources to establish points of reference for the decisions that follow. 2.2 PROGRAM-SPECIFIC OBJECTIVES AND DECISIONS 2.2.1 LAND HEALTH STANDARDS Land Health Standards are expressions of physical and biological condition or degree of function required for sustainable environmental health. These standards engender measurements that describe on- the-ground conditions in relation to the four fundamentals of healthy, properly functioning ecosystems that are identified at 43 CFR § 4180. These fundamentals are: • Watersheds in properly functioning physical condition; soil and plant conditions support infiltration, soil moisture storage, and the release of water that is in balance with climate and landform and maintain or improve water quality, water quantity, and timing and duration of flow. Ecological processes, including the hydrologic cycle, nutrient cycle, and energy flow, are maintained in order to support healthy biotic populations and communities. • Water quality complies with State water quality standards and achieves BLM management objectives. • Habitats are restored or maintained for listed, proposed, candidate and other special status species. BLACK ROCK-HIGH ROCK RMP 2-1 JULY 2004 Chapter 2 –Management Plan Standards are achieved through the use of guidelines developed for specific programs and uses. Because the Standards were originally applied to livestock grazing, guidelines for livestock grazing (Appendix B) will continue to apply to that use.

On Black Rock Desert Trails When Dora Tucker and Nell Murbarger first began exploring the Black Rock country in northwestern Nevada they did not realize what a high, wide and wild country it was.

In the 10,000 square miles of this desert wasteland there isn't a foot of pavement nor a mile of railroad— neither gasoline station nor postoffice. Antelopes out-number human beings fifty to one.

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.

Based on observations that started as early as 1990 to 2014, it appears a small group of elk established a home range within the Santa Rosa Range. This small herd has continued to increase throughout the last two decades. In January of 2013, two cow elk were collared to track movement and use areas. Since the start of that project, to date, one collar has been recovered with data of known use areas. The second collar is due to fall off in August of 2015. In January 2014, the first elk survey flight was conducted. During this survey, a total of 21 elk were observed. All 21 animals were bulls with no cows being located. Prior to this survey, animals have been observed from the air on several occasions, incidentally during other specie surveys. Another follow-up survey was conducted in March 2015 to try to determine the number of elk existing in the Santa Rosa Range. During this flight no elk were observed.

Menardi’s map of Nevada, 1908 Plate 1 Mining districts of Nevada Note: Hyperlinks are denoted by underlined blue text. PREFACE TO THE SECOND EDITION Most of the major changes included in the second edition of Mining Districts of Nevada resulted from mineral assessment work carried out in south central Nevada between 1992 and 1996 (Tingley and others, 1993, 1997). Six new mining districts, Cedar Spring, Gold Range, Jamestown, Pocopah, Rainstorm, and Trappmans, have been added in Nye County and two districts, Joe May Canyon and White Caps, have been added in Clark County. Six Nye County districts, Antelope Springs, Cactus Springs, Clarkdale, Kawich, Wellington, and Wilsons, and three districts in Lincoln County, Don Dale, Groom, and Papoose, have boundary modifications and new material has been added to their descriptions in the text. In the northern part of the state, the boundary of the Argenta district, Lander County, has been modified to reflect the development of a major gold mine; gold has now surpassed barite as the major commodity produced from this district.

D., Advisor Christopher Henry, Ph. D., Committee Member Thom Seal, Ph. D, Graduate School Representative Marsha H. Read, Ph. D., Dean, Graduate School December, 2013 i Abstract The Hycroft gold-silver mine is a low sulfidation epithermal hot spring deposit located 55 miles west of Winnemucca, NV near the Blackrock desert. It is located in the historic Sulphur district, which has had mining on and off since the late 1800’s. Sulphur was the main commodity initially, with the later discovery and mining of silver, alunite, and mercury through the first half of the 20th century. Gold was discovered in the district in 1974 by the Duvall Corporation. The first gold mining and recovery by heap leach was conducted in 1983 by Standard Slag. Allied Nevada acquired the property in 2008 and discovered the Vortex zone through induced polarization and resistivity surveys. The oldest rocks in the region are the Permian Happy Creek Volcanic Series. These are overlain by the Auld Lang Syne Group of metamorphosed argillaceous to sandy sedimentary rock.
