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 scanned topographic base at a scale of 1:24,000, and (3) attribute tables for geologic units (polygons), contacts (arcs), and site-specific data (points). In addition, the data set includes the following graphic and text products: (1) A PostScript graphic plot-file containing the geologic map on a 1:24,000 topographic base accompanied by a Description of Map Units (DMU), a Correlation of Map Units (CMU), and a key to point and line symbols; (2) PDF files of the DMU and CMU, and of this Readme, and (3) this metadata file. The geologic map data base contains original U.S. Geological Survey data generated by detailed field observation and by interpretation of aerial photographs. The map was created by transferring lines from the aerial photographs to a 1:24,000 mylar orthophoto-quadrangle and then to a base-stable topographic map. This map was then scribed, and a .007 mil, right-reading, black line clear film made by contact photographic processes.The black line was scanned and auto-vectorized by Optronics Specialty Company, Northridge, CA. The non-attributed scan was 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 Butler Peak 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 dataset for the Butler Peak quadrangle has also been supported by the U.S. Forest Service, San Bernardino National Forest. The digital geologic map database for the Butler Peak quadrangle has been created as a general-purpose data set that is applicable to other land-related investigations in the earth and biological sciences. For example, the U.S. Forest Service, San Bernardino National Forest, is using the database as part of a study of an endangered plant species that shows preference for particular rock type environments. The Butler Peak 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 Butler Peak 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.

MacColl 1:36,000-scale mapping of the Rattlesnake Mountain pluton. Technical review by David M. Miller led to significant improvements in aspects of the data base, the plot file, and in the discription of the geologic units of the Butler Peak quadrangle. Geologic mapping and digital preparation of this report were sponsored jointly by (1) the National Cooperative Geologic Mapping Program of the U.S. Geological Survey and (2) the U.S. Forest Service (San Bernardino National Forest). In our digital preparation of the data set, carried out in the Geographic Information System laboratory of the Mineral Resources Survey Program of the U.S. Geological Survey in Spokane, Washington, we received valuable assistance from Paul C. Hyndman and from Rachel Hauser at the SCAMP Geographic Information System laboratory in Riverside, California.

Until such standards are adopted, the SCAMP project has developed internal map-accuracy standards for 1:24,000-scale geologic maps produced by the project. Geologic lines and points on 1:24,000 scale geologic maps are judged to meet SCAMP's internal map-accuracy standards if they are located to within +/-15 meters, relative to topographic or cultural features on the base map. Lines and points that meet (or may not meet) the SCAMP internal 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 SCAMP internal 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 SCAMP internal 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 SCAMP internal map-accuracy standard are denoted by solid lines; line data that may not meet the SCAMP internal map-accuracy standard 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 database is considered to be substantially complete in its present form. In future revisions, all polygons will be encoded with polygon-specific geologic data that is currently included in the Description of Map Units in this version (version 1.0). Concentration of geologic observations is lowest in the southwestern part of the quadrangle, but is considered adequate because of the single bedrock unit found there. Granitic rock names follow IUGS (Streckeisen, 1976) nomenclature. Some polygons of the generalized unit Qs, might be assigned to more specific Quaternary units after detailed study. 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 Butler Peak quadrangle are as follows: >Scale (X,Y) = (609.489,609.966) Skew (degrees) = (0.003) >Rotation (degrees) = (-0.025) Translation = (-6246.250,-537.794) >RMS Error (input,output) = (0.001,0.850) > >Affine X = Ax + By + C >Scale (X,Y) = (609.489,609.966) Skew (degrees) = (0.003) >Rotation (degrees) = (-0.025) Translation = (-6246.250,-537.794) >RMS Error (input,output) = (0.001,0.850) > >Affine X = Ax + By + C > Y = Dx + Ey + F > A = 609.489 B = 0.300 C = -6246.250 > D = -0.266 E = 609.966 F = -537.794 Lineage: Process_Step: Process_Description: Field mapping and aerial photograph interpretation; iterative process (H.J.

Process_Date: 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 clear-film, right-reading, 0.007 mil thickness, base-stable blackline positive (made by contact photograph from a scribeguide) of the author-prepared geologic map at 1:24,000 scale. The auto-vectorized, non-attributed scan was prepared by Optronics Specialty Company, Inc. and converted to an ARC/INFO coverage using standard ARC/INFO commands. Registration and transformation were subsequently completed in Spokane (P.M. Cossette). 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 (P.M. Cossette). 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 (P.M. Cossette). The base map image was prepared by scanning a scale-stable clear-film of the U.S. Geological Survey, 1:24,000 Butler Peak 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 500 dpi. The raster scan was converted to a monochromatic image in ARC/INFO. No elements of the base layer are attributed. The base map is provided for reference only (R.M. Hauser and P.M. Cossette).
