The U.S. Geological Survey collected groundwater samples from 49 wells used for domestic and small system drinking water supplies and 10 monitoring wells in San Bernardino County, California in 2018. The wells were sampled for the Mojave Basin (MOBS) Shallow Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project’s assessment of the quality of groundwater resources used for domestic and small system drinking water supplies. Domestic and small-system wells commonly are screened at shallower depths than public-supply wells. The MOBS study unit covered the Upper, Middle, and Lower Mojave River groundwater basins, the...

This dataset contains a provisional release of field observations at sites of fault rupture and ground deformation features where quantitative displacement measurements were obtained. This release does not include associated photographs and some observations where there are outstanding questions about the measurements received; some duplicate observations may exist in this dataset. Photos and resolved measurement data are anticipated for a future release. This dataset consists of a comma-delimited ASCII text file where each line in the file represents an observation, suitable for importing into a spreadsheet, database or GIS application for visualization and analysis. These data are also summarized in a companion...

Data for static groundwater-levels measured in about 645 wells during the period of January-April 2016 by the United States Geological Survey (USGS), the Mojave Water Agency, and other local water districts were compiled to construct a regional water-table map. The downloadable shapefile shows the elevation of the water table in the Mojave River and Morongo groundwater basins. This dataset is a digital representation of the contours presented on Plate 1 of Regional Water Table (2016) in the Mojave River and Morongo Groundwater Basins, Southwestern Mojave Desert, California: U.S. Geological Survey Scientific Investigation Map, doi:10.5066/sim3391, published by Meghan C. Dick and Adam R. Kjos. It is a continuation...

These data on the concentrations of 27 selected elements were collected using a field portable (handheld) X-ray fluorescence (pXRF) instrument (Groover and Izbicki, 2016) equipped with a 4-watt Ta/Au X-ray tube on samples of 1) surficial alluvium, 2) rock, and 3) archived core material and drill cuttings from monitoring wells across an approximately 14,300 square kilometer area in the western part of the Mojave Desert, between 60 to 210 kilometers (km) northeast of Los Angeles, California. These samples were measured using a pXRF as part of a regional-scale investigation of naturally-occurring trace elements (including arsenic, chromium, and uranium) dissolved in groundwater (Groover and Izbicki, 2018), and a local-scale...

This data release supports U.S. Geological Survey (USGS) Scientific Investigations Report 2023-5106, Groundwater Discharge by Evapotranspiration from the Amargosa Wild and Scenic River and Contributing Areas, Inyo and San Bernardino Counties, California. It consists of two comma-separated values (CSV) files containing data collected at two USGS atmospheric monitoring locations (USGS site identification numbers 355846116160401 and 355918116161801) beginning in January 2018 and lasting for approximately 1 year. The data include 30-minute values for cumulative normalized flux for 6 circular areas around each site and 30-minute values for unadjusted total evapotranspiration. The radii of the circular areas are 25, 50,...

The U.S. Army Fort Irwin National Training Center (NTC), approximately 35 mi north-northeast of Barstow, California, covers approximately 1,177 square miles, and is comprised of ten groundwater basins, three of which have been subdivided into subbasins on the basis of additional hydrologic testing. Since the early 1990s, the U.S. Geological Survey (USGS) has been studying water resources issues at Fort Irwin. One issue of concern is the potential effect of groundwater development resulting from planned training expansion and infrastructure at the NTC on natural springs and seeps, an important water source for wildlife. In 2010, the USGS entered into cooperative agreements with the U.S. Army to complete studies of...

This product is a collection of digital data that document fault rupture and ground-deformation features produced by the Ridgecrest M6.4 and M7.1 earthquake sequence of July 4 and 5, 2019. These datasets are described and more fully discussed in Ponti and others (2020) (see External Resources Section below for the full reference). Included in this collection are: GIS Shapefile and KMZ file of field-verified fault rupture and ground deformation features from direct field mapping, or interpreted from ground observations, airborne and satellite optical imagery, digital surface models derived from lidar and structure-from-motion optical image analysis, sub-pixel correlation of multi-temporal optical imagery, and phase...

This map geodatabase digitally represents the general distribution of bedrock geologic map units in the Turtle Mountains area, California, as portrayed in Plate 1 of USGS Bulletin 1713-B, Mineral resources of the Turtle Mountains Wilderness Study Area, San Bernardino County, California (1988), https://doi.org/10.3133/b1713B. The map covers parts of the Rice, Turtle Mountains, and Savahia Peak 15’ quadrangles at 1:48,000 scale. Plate 1 is titled Mineral resource potential map of the Turtle Mountains Wilderness Study Area, San Bernardino County, California. The current database represents the geologic map base of Plate 1, but does not include mines, prospects, and mineral-potential evaluations that Plate 1 also portrays....
