U.S. Geological Survey and A. M. Leszcykowski and J. D. Causey U.S
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. -

2020 Volume 2
Society for the Conservation of Bighorn Sheep Sheep Sheet - Volume 2 – September 2020 www.desertbighorn.org Before the project began, collection box area in sad shape After the project: a formal, robust spring box Redwood Spring Box Installed at Castle Mine Spring By Debbie Miller Marschke SCBS has been working to improve the natural spring at the Castle Mine location for many years. Mining ruins and a dilapidated cabin remain as evidence that this spring has a history of folks teasing out the precious water from this location. There is always an overgrowth of vegetation at the spring which is proof positive that the spring is active, even if the flow rate is minimal. Bighorn Sheep biologists have GPS data from collared sheep in the mountain range that prove the Bighorn Sheep wander along the backbones of the ridges; occasionally they visit this spring but they mainly depend on the big game guzzlers to the north of this location. Nevertheless, each water location in a mountain range is crucial in the network of water sources available. SCBS crews have dug out and cleared the guzzler intake Johnson screen several times on previous occasions which has been very frustrating because a spring box had never been installed. The water seeps from the entrance of an old mine adit in the side of a hill. The hill face and adit entrance are unstable, and thus dirt caves in and has buried the intake system time and time again. On the weekend of May 15-17, 2020, a modest SCBS strike force sought to make one final but meaningful attempt to boost water output from Castle Mine spring. -

LOCAL AGENCY FORMATION COMMISSION FOR SAN BERNARDINO COUNTY 215 North D Street, Suite 204, San Bernardino, CA 92415-0490 (909) 383-9900 Fax (909) 383-9901 E-MAIL: [email protected] www.sbclafco.org DATE: JULY 8, 2013 FROM: KATHLEEN ROLLINGS-McDONALD, Executive Officer SAMUEL MARTINEZ, Assistant Executive Officer MICHAEL TUERPE, Project Manager TO: LOCAL AGENCY FORMATION COMMISSION SUBJECT: Agenda Item #10: Service Review for the Remainder of the South Desert Communities INITIATED BY: San Bernardino Local Agency Formation Commission RECOMMENDATION: Staff recommends the Commission receive and file the service review for the remainder of the unincorporated South Desert communities that are identified in this report. INTRODUCTION San Bernardino LAFCO has chosen to undertake its service reviews on a regional basis. The Commission has divided the county into four separate regions, with the South Desert Region generally encompassing the Morongo Basin, the Colorado River communities, Baker, and everything in between. This report covers the remainder of the South Desert region that has not been covered in previous service reviews. Most of the areas that are identified in this report are small communities that have little or no access to services, nor are they within the boundaries of a special district for which the Commission establishes a sphere of influence. However, a service review is provided to identify and provide information on the services delivered, or lack of services, within these community pockets that exist in the South -

U/Pb zircon ages provide temporal control for describing variations in rock and zircon geochemistry that reflect differences in magma source components. These source signatures are discernible through mixing and fractionation processes associated with magma ascent and emplacement. The oldest well-dated Jurassic rocks defining initiation of the Jurassic pulse are a 183 Ma monzodiorite and a 181 Ma ignimbrite. Early to Middle Jurassic intrusive rocks comprising the main stage of magmatism include two high K calc-alkalic groups; to the north, the deformed 183 to 172 Ma Fort ___________________________________________________________________ This is the author's manuscript of the article published in final edited form as: Barth, A. -
