Description: Bedrock maps bedrock geology units and major faults for Maine at 1:500,000 scale. The dataset was developed by the Maine Geological Survey (MGS) from the "Bedrock Geologic Map of Maine, Osberg, Hussey, and Boone, 1985". The data for this dataset were scanned off 1:500,000 scale mylars by the United States Geological Survey (USGS) in 1987. The original bedrock unit codes were added by the J.W. Sewall Co. in 1990 for the Maine Low-Level Radioactive Waste Authority. In 1994, staff at MGS identified and added codes for major bedrock faults. Bedrock UNIT codes assigned to this dataset are available in comma delimited text, and .dbf format, on the Maine GIS Data Catalog.
