The bedrock geology for the coverage area is provided as a polygon coverage with bedrock unit information included. Mineral resources and geologic faults are provided as point and line files, respectively, to overlay the geology coverage. Detailed geologic information is provided in the attribute tables for these files, and .avl legend files are provided.
