Most positions on the map are estimated to be accurate closer than 30 m horizontally. There is no elevation data in the database. Logical_Consistency_Report: Map elements were visually checked by the author for overshoots, undershoots, duplicate features, and other errors. The report is preliminary and has not been thoroughly reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature. The map was reviewed by another geologist for consistency with basic geologic principles and general conformity to USGS mapping standards. Completeness_Report: This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature. Data is complete: no features were eliminated or generalized. There is no cross section and the ARC/INFO database lacks a unit properties table, although unit properties are described in the text explanation. A base map coverage is not included. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: >Lines were primarily positioned by interpretation of published preexisting geological mapping, thesis maps, and unpublished geological mapping. Lines were scanned from the basemap using a scanner with the following parameters: >density = 400 400 >x (in) = >y (in) = >output file x pixel limits = >output file y pixel limits = >speed = 100 % >turbo-optimize = 0 >scan line orientation = 4 >deskew angle = 0.000 >output file size = >scan time = >Invert: OFF >Mirror: OFF >basic thresholding >speckle size = 0 x 0 pixels >hole filling size = 0 x 0 pixels >distortion correction: OFF >Scan Type: Lineart >Format : Image Systems RLC >The scanned lines were vectorized with the CADCORE program. >Additional lines and point observations were added using a digitizer tablet with resolution of 0.001 inch.

Lineage: Process_Step: Process_Description: The scanned lines were edited in DESIGN-CAD and brought into ARC/INFO with the DXFARC command. Two coverages were initially created, one containing polygons, the other containing all other features (labels, fold axes, decorations, etc.).
