“…1), contains a Cenozoic section that, in its upper part, is thickened compared to a similar section in the San Fernando Valley and thrust over that section along the Santa Susana Fault (SSF) and MHF (Winterer and Durham, 1954;Yeats, 1987). Basement depth in the EVB ranges from 1.5 to 4 km (Stitt, 1986;Dibblee, 1996). North of the SGF are the Oligocene to Quaternary Soledad sedimentary basin, east of line 2, and the upper Miocene and Pliocene Ridge sedimentary basin, west of line 2 (Fig.…”

“…Numerous faults traverse the Antelope Valley, El Mirage Valley, and Upper Mojave River Valley groundwater basins; the reader is referred to the following publications for detailed discussions on their locations and extents: Dibblee (1959Dibblee ( , 1960aDibblee ( , 1960bDibblee ( , 1960cDibblee ( , 1963, Mabey (1960), Dutcher and Worts (1963), Jennings and others (1977), Dokka and Travis (1990), Ward andothers (1993), andBryant (2005). In the southern part of the study area, the tectonic activity associated with the San Andreas Fault Zone has had the most influence on the geologic structure, climate, and hydrologic setting because transpression, or contraction, across the fault has caused uplift of the San Gabriel Mountains ( fig.…”

“…A complex pattern of deeply incised, redirected, and truncated stream channels has formed on the north side of the San Gabriel Mountains as result of movement along the San Andreas Fault Zone. A few unnamed northwest-trending faults have been mapped in the alluvium within the study area (Dibblee, 1959(Dibblee, , 1960a(Dibblee, , 1960b(Dibblee, , 1960cBryant, 2005;Siade and others, 2014; fig. 2), but their relation and connectivity to the San Andreas Fault are uncertain, and their depth and effects on groundwater flow are unknown.…”

ISSN 2328-0328 (online) iii AcknowledgmentsThis study was completed in cooperation with the Mojave Water Agency. Their support and provision of resources were invaluable for the completion of the study. Appreciation is also extended to the staff of the Phelan-Piñon Hills Community Services District for access to their data and assistance in the field.Further appreciation is extended to our U.S. Geological Survey colleagues Joseph M. Nawikas and David B. Dillon for their efforts in collecting the groundwater-level data from the field, to Andrew Y. Morita for collecting the gravity data, and to Sally F. House and Donald J. Martin for creating the visualizations used in this report. A, 1980-2015, and B, 1950-2015 and 1915-2015 DatumVertical coordinate information is referenced to the North American Vertical Datum of 1988 (NAVD 88).Horizontal coordinate information is referenced to the North American Datum of 1983 (NAD 83).Altitude, as used in this report, refers to distance above the vertical datum. Well-Numbering SystemWells are identified and numbered according to their location in the rectangular system for the subdivision of public lands. Identification consists of the township number, north or south; the range number, east or west; and the section number. Each section is divided into 16 40-acre tracts lettered consecutively (except "I" and "O"), beginning with "A" in the northeast corner of the section and progressing in a sinusoidal manner to "R" in the southeast corner. Within the 40-acre tract, wells are sequentially numbered in the order they are inventoried. The final letter refers to the base line and meridian. In California, there are three base lines and meridians: Humboldt (H), Mount Diablo (M), and San Bernardino (S). All wells in the study area are referenced to the San Bernardino base line and meridian (S). Well numbers consist of 15 characters and follow the format 005N008W13R001S. In this report, well numbers are abbreviated and written 5N/8W-13R1. Wells in the same township and range are referred to only...
