Cucamonga Creek and Tributaries, San Bernardino and Riverside Counties, California
STATEMENT OF FINDINGS CUCAMONGA CREEK AND TRIBUTARIES SAN BERNARDINO AND RIVERSIDE COUNTIES CALIFORNIA 1. ' As District Engineer, Los Angeles District, U. S. Army Corps of Engineers, I have reviewed and evaluated, in what I believe to be the public interest, the project Tor Cucamonga Creek, West Cucamonga Creek, and Deer Creek channel improvements, from the Sari Gabriel Mountains to Prado Reservoir, San Bernardino and Riverside Counties, California, which is outlined in the project description section of this environmental statement. In evaluating this project, I have considered all project documents, comments by concerned agencies and individuals, and possible alternatives. 2. My staff has (a) compiled an environmental statement that covers the fundamental and basic environmental impacts; (b) computed the cost and economic impacts of the proposed project; (c) considered the project effects on the surrounding community; (d) considered alternatives; and (e) prepared engineering plans for the project. I have reviewed their findings and the comments of Federal, State, local agencies, and interested parties. \ 3. In my evaluation the following points were considered: a. ' Economic considerations. The proposed project will provide flood damage reduction for floods up to standard-project-fiood magnitude to developed areas consisting of valuable residential, commercial, agricultural, and industrial property, important -r-utilities, arterial and interstate highways, an international airport, and transcontinental railroad lines serving the area. b. ‘ Engineering considerations. The project is designed to provide flood protection by providing debris basins and increased channel capacity. The channel is also designed to divert runoff into spreading basins for ground water recharge. c. ' Social well-being considerations. The well-being of the people in the project area will be improved because of flood protection that will reduce the possibility of loss of life, injury', disease, and inconvenience. -

DEPARTMENT OF THE INTERIOR TO ACCOMPAN~ MAP MF-1493-A UNITED STATES GEOLOGICAL SURVEY IIINE1lAL RESOURCE POTBM"nAL OP THE BIGHORN MOUNTAINS WU.DERNJmS STUDY AREA (CDCA-217), SAN BERNARDINO COUNTY, CALIFORNIA SUMMARY REPORT By Miathan C. Matti, Brett P. Cox, Ecblrdo A. Rodriguez, CUrtis M. Obi, Robert E. Powell, Margaret E. Hinkle, and Andrew Griscom U.S. Geological Survey and Charles Sabine and Gary J. Cwick U.S. Bureau of Mines STUDIES RELATED TO WU.DERNESS 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 in 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 Bighorn Mountains Wilderness Study Area (CDCA-217), California Desert Conservation Area, San Bernardino County, California. SUMMARY Geological, geochemical, and geophysical evidence, together with a review of historical mining and prospecting activities, suggests that most of the Bighorn Mountains Wilderness Study Area has low potential for the discovery of all types of mineral and energy resources-including precious and base metals, building stone and aggregate, fossil fuels, radioactive-mineral resources, . and geothermal resources. Low-grade mineralization has been documented in one small area near Rattlesnake Canyon, and this area has low to moderate potential for future small-scale exploration and development of precious and base metals. Thorium and uranium enrichment have been documented in two small areas in the eastern part of the wilderness study area; these two areas have low to moderate potential for future small-scale exploration and development of radioactive-mineral resources. -
UNIVERSITY of CALIFORNIA Los Angeles Southern California
UNIVERSITY OF CALIFORNIA Los Angeles Southern California Climate and Vegetation Over the Past 125,000 Years from Lake Sequences in the San Bernardino Mountains A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Geography by Katherine Colby Glover 2016 © Copyright by Katherine Colby Glover 2016 ABSTRACT OF THE DISSERTATION Southern California Climate and Vegetation Over the Past 125,000 Years from Lake Sequences in the San Bernardino Mountains by Katherine Colby Glover Doctor of Philosophy in Geography University of California, Los Angeles, 2016 Professor Glen Michael MacDonald, Chair Long sediment records from offshore and terrestrial basins in California show a history of vegetation and climatic change since the last interglacial (130,000 years BP). Vegetation sensitive to temperature and hydroclimatic change tended to be basin-specific, though the expansion of shrubs and herbs universally signalled arid conditions, and landscpe conversion to steppe. Multi-proxy analyses were conducted on two cores from the Big Bear Valley in the San Bernardino Mountains to reconstruct a 125,000-year history for alpine southern California, at the transition between mediterranean alpine forest and Mojave desert. Age control was based upon radiocarbon and luminescence dating. Loss-on-ignition, magnetic susceptibility, grain size, x-ray fluorescence, pollen, biogenic silica, and charcoal analyses showed that the paleoclimate of the San Bernardino Mountains was highly subject to globally pervasive forcing mechanisms that register in northern hemispheric oceans. Primary productivity in Baldwin Lake during most of its ii history showed a strong correlation to historic fluctuations in local summer solar radiation values. -
The High Desert Alfalfa Production Region of California Is Located From
ALFALFA PRODUCTION IN THE HIGH DESERT Steve B. Orloff and Rhonda R. Gildersleeve' ( The high desert alfalfa production region of California is located from the Mojave Desert which includes portions of Los Angeles, San Bernardino, and Kern Counties, north to Inyo and Mono Counties. Alfalfa fields in the high desertare clustered in isolated valleys with long stretchesof desert betweenthem. Thesevalleys are so isolated and dispersedthat the climate, growing conditions, soil types, and even the production practices and problems can vary considerably between production areas. The main alfalfa production areas and their characteristics are presentedin table 1. Many people mistakenly believe that "desert" is "desert", and lump the high desert with the low desert. However, those that are familiar with both areas realize there are very distinct differences. The climate in the high desert is unique, but has similarities with both the low desert and the colder northern parts of the state. The high desert climate is characterized by large swings in temperature, both from day to night and from summer to winter. Winter low temperatures between zero to ten degrees(negative 10 to 20 in the northern mountain valleys) have been recorded (particularly this last year), while summer temperatures exceeding 110 degrees commonly occur. A drop in temperature of 40 to 50 degreesbetween day and night is not uncommon. Spring frosts as late as April (and even June in northern high-elevation areas) are routine, and slow alfalfa growth. Winds are a common denominator throughout all of the high-desert valleys. Most areas have a prevailing "breeze" of 10 to 20 miles per hour during the day. -
Scott Zylstra: “Late Cretaceous Metamorphic and Plutonic of Proterozoic Metasediments of Ontario Ridge, Eastern San Gabriel
LATE CRETACEOUS PLUTONIC AND METAMORPHIC OVERPRINT OF PROTEROZOIC METASEDIMENTS OF ONTARIO RIDGE, EASTERN SAN GABRIEL MOUNTAINS, CALIFORNIA A Thesis Presented to the Faculty of California State Polytechnic University, Pomona In Partial Fulfillment Of the Requirements for the Degree Master of Science In Geological Sciences By Scott B. Zylstra 2017 ACKNOWLEDGEMENTS Many thanks to Drs. Jonathan Nourse and Nicholas Van Buer for countless hours in research, assistance and editing on this project; to Zhan Peng, Anthony LeBeau and Karissa Vermillion for laboratory assistance; to the MENTORES program and the Cal Poly Geology Department for funding; to Joshua Schwartz and Carl Jacobson for valuable insight; and to Jennifer, Gwendolyn and Lydia Jean Zylstra, without whom this work would not be possible (and with whom sometimes has been scarcely possible). iii ABSTRACT The rifting of Rodinia, particularly in western Laurentia, has been a longstanding geologic problem, as Proterozoic rocks in the western U.S. are few and far between. The eastern San Gabriel Mountains contain a large metasedimentary package that has never been dated or thoroughly mapped. We present U-Pb detrital zircon geochronology results of 439 grains dated at CSUN’s LA-ICPMS; also 24 plutonic grains and 19 metamorphic rims of detrital grains analyzed on Stanford’s SHRIMP-RG, along with a detailed map, cross section and stratigraphic column for these Ontario Ridge metasediments. Probability plots of 206Pb/207Pb ages for five quartzite samples show three distinct peaks at ~1200, 1380-1470 and 1740-1780 Ma. Maximum depositional age is constrained by 3 grains between 906 to 934 Ma, which are 11-28% discordant. -

Keys Ranch: Where Time Stood Still
National Park Service Teaching with Historic Places U.S. Department of the Interior Keys Ranch: Where Time Stood Still Keys Ranch: Where Time Stood Still (Photo by Harmon and Nelda King, National Park Service) In the high desert of California, flesh-colored boulders rise up out of the stark landscape and embrace a small valley where Keys Ranch stands. Strangely shaped trees cast long shadows on the sides of the simple wooden ranch structures. Animal tracks in the sand tell of the previous night's adventures when scorpions, kangaroo rats, snakes, and bobcats battled for survival. This seemingly hostile desert environment was settled much later than other more productive areas of the West. Yet it was here, in 1917, that Bill Keys chose to establish a ranch and raise a family. Keys and other 20th-century homesteaders lived much as earlier pioneers in the West had, working hard to make their marginal land holdings successful. Today, Keys Ranch is preserved as part of Joshua Tree National Park.
