The quadrangle, situated in Joshua Tree National Park in the eastern Transverse Ranges physiographic and structural province, encompasses parts of the northwestern Eagle Mountains, east-central Pinto Basin, and eastern Pinto Mountains. The quadrangle is underlain by a basement terrane comprising metamorphosed Proterozoic strata, Mesozoic plutonic rocks, and Jurassic and Mesozoic and (or) Cenozoic hypabyssal dikes. The basement terrane is capped by a widespread Tertiary erosion surface preserved in remnants in the Pinto and Eagle Mountains and buried beneath Cenozoic deposits in Pinto Basin. Locally, a cover of Miocene sedimentary deposits and basalt overlie the erosion surface. A sequence of at least three Quaternary pediments is planed into the north piedmont of the Eagle Mountains, each in turn overlain by successively younger residual and alluvial, surficial deposits. The Tertiary erosion surface is deformed and broken by north-northwest-trending, high-angle, dip-slip faults in the Pinto and Eagle Mountains and an east-west trending system of high-angle dip- and left-slip faults along the range fronts facing Pinto Basin. In and around the San Bernardino Wash quadrangle, faults of the north-northwest-trending set displace Miocene sedimentary rocks and basalt deposited on the Tertiary erosion surface and some of the faults may offset Pliocene and (or) Pleistocene deposits that accumulated on the oldest pediment. Faults of this system appear to be overlain by Pleistocene deposits that accumulated on younger pediments. East-west trending faults are younger than and perhaps in part coeval with faults of the northwest-trending set. The San Bernardino Wash database was created using ARCVIEW and ARC/INFO, which are geographical information system (GIS) software products of Envronmental Systems Research Institute (ESRI). The database comprises five coverages: (1) a geologic layer showing the distribution of geologic contacts and units; (2) a structural layer showing the distribution of faults (arcs) and fault ornamentation data (points); (3) a layer showing the distribution of dikes (arcs); a structural point data layer showing (4) bedding and metamorphic foliation attitudes, and (5) cartographic map elements, including unit label leaders and geologic unit annotation. The dataset also includes a scanned topographic base at a scale of 1:24,000. Within the database coverages, geologic contacts , faults, and dikes are represented as lines (arcs and routes), geologic units as areas (polygons and regions), and site-specific data as points. Polygon, region, arc, route, and point attribute tables uniquely identify each geologic datum and link it to descriptive tables that provide more detailed geologic information. The digital database is accompanied by two derivative maps: (1) A portable document file (.pdf) containing a navigable graphic of the geologic map on a 1:24,000 topographic base and (2) a PostScript graphic-file containing the geologic map on a 1:24,000 topographic base. Each of these map products is accompanied by a marginal explanation consisting of a Description of Map Units (DMU), a Correlation of Map Units (CMU), and a key to point and line symbols. The database is further accompanied by three document files: (1) a readme that lists the contents of the database and describes how to access it, (2) a pamphlet file that describes the geology of the quadrangle and (3) this metadata file. Purpose: The data set for the San Bernardino Wash quadrangle has been prepared by the Southern California Areal Mapping Project (SCAMP), a cooperative project sponsored jointly by the U.S. Geological Survey and the California Geological Survey. The San Bernardino Wash data set represents part of an ongoing effort to create a regional GIS geologic database for southern California. This regional digital database, in turn, is being developed as a contribution to the National Geologic Map Database of the National Cooperative Geologic Mapping Program of the USGS. The San Bernardino Wash database has been prepared in cooperation with the National Park Service as part of an ongoing project to provide Joshua Tree National Park with a geologic map base for use in managing Park resources and developing interpretive materials. The digital geologic map database for the San Bernardino Wash quadrangle has been created as a general-purpose data set that is applicable to land-related investigations in the earth and biological sciences. Along with geologic map databases in preparation for adjoining quadrangles, the San Bernardino Wash database has been generated to further our understanding of bedrock and surficial processes at work in the region and to document evidence for seismotectonic activity in the eastern Transverse Ranges. The database is designed to serve as a base layer suitable for ecosystem and mineral resource assessment and for building a hydrogeologic framework for the Pinto Basin. Supplemental_Information: Map nomenclature and symbols Within the geologic map database, map units are identified by standard geologic map criteria such as formation-name, age, and lithology. The authors have attempted to adhere to the stratigraphic nomenclature of the U.S. Geological Survey and the North American Stratigraphic Code, but the database has not received a formal editorial review of geologic names. Geologic map unit labels are present in three forms in the database. First, map unit labels are entered into the database through various items in the polygon attribute table, dike arc attribute table, and region attribute tables. Geologic map units are tabulated in items such as UNIT_LABEL and POLY_LABEL, where they are identified by plain-text unit labels (e.g., Qyamg1, Prpqp). These labels do not show subscript offsets and do not contain conventional stratigraphic age symbols, i.e., Proterozoic appears as 'Pr'. Second, for the purpose of plotting the map, the item PLOT_LABEL, located in the polygon attribute and map display tables, identifies the unit label as it is plotted by Arc/Info (e.g., Qyamg1, .pat contains AREA, PERIMETER, cover#, and cover-ID; .aat contains FNODE#, TNODE#, LPOLY#, RPOLY#, LENGTH, cover#, and cover-ID. User-defined attributes are described in detail below. (1) The coverage sbwash_geo includes the following feature tables: (a) A polygon attribute table (sbwash_geo.pat) that lists labels for the geological characteristics and identifies plot labels for the rock units represented in the Postscript (.ps) and Portable Document Format (.pdf) plotfiles of the geologic maps; (b) Region subclass attribute tables that describe the geospatial distribution of rock units represented in the Postscript (.ps) and Portable Document Format (.pdf) plotfiles of the geologic maps (sbwash_geo.patrockunit), the hierarchical array of stratigraphic parents of rock units in the crystalline basement (sbwash_geo.patbasement1, sbwash_geo.patbasement2, sbwash_geo.patbasement3, sbwash_geo.patbasement4), the hierarchical array of stratigraphic parents of rock units in sedimentary and volcanic cover to the basement rocks (sbwash_geo.patcover2), and the hierarchical array of stratigraphic parents of surficial units (sbwash_geo.patsurficial1, sbwash_geo.patsurficial2, sbwash_geo.patsurficial3, sbwash_geo.patsurficial4, sbwash_geo.patsurficial5). This hierarchy of stratigraphic units can be related in ArcInfo, ArcMap or ArcView to display or plot more generalized, derivative geologic maps than that represented in Postscript (.ps) or Portable Document Format (.pdf) files. (c) A region subclass attribute table that describes surface units (veneers) (sbwash_geo.patsurfunit). (d) A region subclass attribute table that shows those areas where unit identification is uncertain (sbwash_geo.patident). (e) An arc attribute table (sbwash_geo.aat) that describes the contacts that bound rock-unit polygons. (2) The coverage sbwash_flt contains and displays the complete distribution of fault features within the extent of the San Bernardino Wash quadrangle. Structural line ornamentation is included in this layer as point data. Faults are characterized in two route attribute tables (sbwash_flt.ratsegment and sbwash_flt.ratfault). (3) The coverage sbwash_dike includes an arc attribute table (sbwash_dike.aat) that describes hypabyssal dikes. Dikes are planar intrusive features that intersect the Earth's surface as linear features; they are represented as lines where their surface widths are too narrow to be represented as areal features at a scale of 1:24,000. (4) The coverages sbw_structure includes a point attribute tables (sbw_structure.pat) that describe geologic structural point data, including the types and orientation of bedding and foliation. An annotation subclass (anno.dip - planar data) displays the dip values associated with each point datum. (5) The coverage sbwash_carto includes both geologic unit symbol annotation and an arc attribute table (sbwash_carto.aat) that displays annotation leaders. Unit symbols placed outside the perimeter of a particular polygon are identified by annotation leaders.
