Created using Environmental Systems Research Institute's ARC/INFO software, the data base consists of the following items: (1) a map coverage showing geologic contacts and units, (2) a separate coverage layer showing structural data, (3) a scanned topographic base at a scale of 1:24,000, and (4) attribute tables for geologic units (polygons), contacts (arcs), and site-specific data (points). The data base is accompanied by a readme file and this metadata file. In addition, the data set includes the following graphic and text products: (1) A portable document file (.pdf) containing a browse-graphic of the geologic map on a 1:24,000 topographic base. The map 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. (2) Separate .pdf files of the DMU and CMU, individually. (3) A PostScript graphic plot-file containing the geologic map on a 1:24,000 topographic base accompanied by the marginal explanation. (4) A pamphlet that summarizes the late Cenozoic geology of the Cougar Buttes quadrangle. The geologic map data base contains original U.S. Geological Survey data generated by detailed field observation and by interpretation of aerial photographs, including low-altitude color and black-and-white photographs and high-altitude infrared photographs. The map was created by transferring lines from the aerial photographs to a 1:24,000 topographic base via a mylar orthophoto-quadrangle or by using a PG-2 plotter. The map was then scribed, scanned, and imported into ARC/INFO, where the database was built. Within the database, geologic contacts are represented as lines (arcs), geologic units as polygons, and site-specific data as points. Polygon, arc, and point attribute tables (.pat, .aat, and .pat, respectively) uniquely identify each geologic datum and link it to other tables (.rel) that provide more detailed geologic information. Purpose: The data set for the Cougar Buttes 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 Division of Mines and Geology, as part of an ongoing effort to utilize a Geographical Information System (GIS) format to create a regional digital geologic database for southern California. This regional database is being developed as a contribution to the National Geologic Map Data Base of the National Cooperative Geologic Mapping Program of the USGS. Development of the data set for the Cougar Buttes quadrangle has also been supported by the Mojave Water Agency and U.S. Forest Service, San Bernardino National Forest. The digital geologic map database for the Cougar Buttes quadrangle has been created as a general-purpose data set that is applicable to other land-related investigations in the earth and biological sciences. In cooperation with the Water Resources Division of the U.S. Geological Survey, we have used our mapping in the Cougar Buttes and adjoining quadrangles together with well log data to develop a hydrogeologic framework for the basin. In an effort to understand surficial processes and to provide a base suitable for ecosystem assessment, we have differentiated surficial veneers on piedmont and pediment surfaces and distinguished the various substrates found beneath these veneers. Currently, the geologic database for the Cougar Buttes quadrangle is being applied in groundwater investigations in the Lucerne Valley basin (USGS, Water Resources Division), in biological species studies of the Cushenbury Canyon area (U.S. Forest Service, San Bernardino National Forest), and in the study of soils on various Quaternary landscape surfaces on the north piedmont of the San Bernardino Mountains (University of New Mexico). The Cougar Buttes database is not suitable for site-specific geologic evaluations at scales greater than 1:24,000 (1 in = 2,000 ft).

The data should not be used for purposes of site-specific land-use planning or site-specific geologic evaluations. The database is sufficiently detailed to identify and characterize many actual and potential geologic hazards represented by faults and landslides. However, it is not sufficiently detailed for site-specific determinations or evaluations of those features. Faults shown do not take the place of fault-rupture hazard zones designated by the California State Geologist (see Hart, 1988). Use of the Cougar Buttes geologic-map database should not violate the spatial resolution of the data. Although the digital form of the data removes the constraint imposed by the scale of any derivative maps, the detail and accuracy issues inherent in map scale limitations are also present in the digital data. The fact that this database was edited at a scale of 1:24,000 means that higher-resolution data generally are not present in the dataset. Plotting at scales larger than 1:24,000 will not yield greater, real detail, although it may reveal fine-scale irregularities beyond the intended resolution of the database. Similarly, although higher-resolution data is incorporated at a few places, the resolution of the combined output will be limited by the lower-resolution data. This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code.

Browse_Graphic_File_Type: jpg Data_Set_Credit: Our representation and interpretation of the surficial geology in the Cougar Buttes quadrangle has benefited from discussions about surficial processes in general and soils in particular with Leslie D. McFadden and Martha C. Eppes. Visits to soil pits dug by Martha C. Eppes and discussion of her findings in and around the Cougar Buttes quadrangle have contributed to our understanding of age and shallow subsurface relations among various units. Interpretation of the subsurface geology was made possible by access to water-monitoring well records provided by the Water Resources Division of the U.S. Geological Survey and by water-monitoring and water well records provided by the Mojave Water Agency and the California Department of Water Resources. Roland Hall retrieved the available records from the latter two agencies. Our interpretation of subsurface relations was enhanced by discussions with Jill N. Densmore-Judy and Peter Martin. In our mapping in the Cougar Buttes quadrangle, we were guided in part by the findings of previously published maps: (1) 1:24,000-scale mapping of the Blackhawk landslide by Shreve (1968), (2) 1:24,000-scale mapping of the quadrangle by Sadler (1982), and (3) 1:62,500-scale mapping of the quadrangle by Dibblee (1964). We thank Fred K. Miller for his notes and observations on plutonic rocks at various localities on Cougar Buttes, and for scribing the geologic map in preparation for scanning. Technical reviews by Scott C. Lundstrom and John C. Tinsley, III have led to significant improvements in the data base, the plot file, and in the discussion of the geology of the Cougar Buttes quadrangle in the accompanying summary pamphlet. Geologic mapping, topical studies, and digital preparation of this report were sponsored jointly by (1) the National Cooperative Geologic Mapping Program of the U.S. Geological Survey, (2) the Mojave Water Agency, and (3) the U.S. Forest Service (San Bernardino National Forest). The U.S. Geological Survey's Photogrammetric Plotter Laboratory in Denver, Colorado (James Messerich, photogrammetrist) supported the transfer of geologic linework and point data from aerial photographs to a scale-stable cartographic base. In our digital preparation of the data set, carried out in the Spokane Field Office Geological Information System laboratory of the Mineral Resources Survey Program of the U.S. Geological Survey in Spokane, Washington, we received helpful assistance from Paul C. Hyndman and Rachel Hauser.

Lines and points that meet (or may not meet) this map-accuracy standard are identified both in the digital database and on derivative geologic-map plots. Within the database, line and point data that are judged to meet the map-accuracy standard are denoted by the attribute code .MEE. (meets) in the appropriate data table; line and point data that may not meet the map-accuracy standard are denoted by the attribute code .MNM. (may not meet). On any derivative geologic-map plot, line data that are judged to meet the map-accuracy standard are denoted by solid lines; line data that may not meet the map-accuracy atandard are denoted by dashed or dotted lines. There is no cartographic device for denoting the map-accuracy for geologic-point data (eg. symbols representing bedding, foliation, lineations, etc.). Logical_Consistency_Report: Polygon and chain-node topology present. The areal extent of the map is represented digitally by an appropriately projected (Polyconic projection), mathematically generated box. Consequently, polygons intersecting the lines that comprise the map boundary are closed by that boundary. Polygons internal to the map boundary are completely enclosed by line segments which are themselves a set of sequentially numbered coordinate pairs. Point data are represented by coordinate pairs. Completeness_Report: The geologic map and digital database of the Cougar Buttes 7.5' quadrangle contain new data that have been subjected to rigorous review and are a substantially complete representation of the current state of knowledge concerning the geology of the quadrangle. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The maximum transformation RMS error acceptable for 7.5' quadrangle transformation and data input is 0.003 (1.8 meters). Horizontal positional accuracy was checked by visual comparison of hard-copy plots with base-stable source data. Transformation data (initial DXF scan data format to ARC/INFO coverage) for the Cougar Buttes quadrangle are as follows: >Scale (X,Y) = (609.687,609.887) Skew (degrees) = (0.000) >Rotation (degrees) = (-0.041) Translation = (-6359.613,-768.716) >RMS Error (input,output) = (0.001,0.847) > >Affine X = Ax + By + C > Y = Dx + Ey + F > A = 609.687 B = 0.437 C = -6359.613 > D = -0.440 E = 609.887 F = -768.716 > > Lineage: Process_Step: Process_Description: Field mapping and aerial photograph interpretation; iterative process (J.C.

Process_Date: 1998-1999 Process_Step: Process_Description: The geologic map information was scanned (initial raster scan in MS-DOS TIF format, 1200 dots per inch) from a base-stable original of the author-prepared geologic map at 1:24,000 scale. Normally, the base-stable original for scanning would be produced from scribeguide to clear-film, right-reading, 0.007 mil thickness, blackline positive. For the Cougar Buttes quadrangle, however, it was produced from scribeguide to clear-film, left-reading, 0.004 mil thickness, blackline positive. This original was sandwiched with a mylar sheet to bring the thickness to 0.007 mil, then digitally reversed to right-reading by Optronics Specialty Company, Inc.The auto-vectorized, non-attributed scan was prepared by Optronics and converted to an ARC/INFO coverage using standard ARC/INFO commands. Registration and transformation were subsequently completed. Geologic lines, and polygons are represented in the geology coverage. Geologic points such as attitudes were digitized into a separate geologic points coverage using a Mayline Futur-Matic digitizing table. Lines, points, and polygons were edited and attributed using standard ARC/INFO commands. Digitizing and editing artifacts significant enough to display at a scale of 1:24,000 were corrected. The base map image was prepared by scanning a scale-stable clear-film of the U.S. Geological Survey, 1:24,000 Cougar Buttes 7.5'quadrangle (1971) topographic map. Scanning was done using an Anatech Eagle 4080 monochrome 800 dots per inch (dpi) scanner, at a resolution of 500dpi. The raster scan was converted to a monochromatic image (Geotiff format) in ARC/INFO. No elements of the base layer are attributed. The base map is provided for reference only.
