Bdrkpy

The Bdrkpy file contains information created by Oreskovich, about the location, shape, and type of Precambrian bedrock outcrop in the middle Minnesota River valley from about the northern tip of Renville County eastward to Township 111 North – Range 32 West in Nicollet County (see complete description in Methods section of this report, and Oreskovich, 1998). In the northern tip of Redwood County, where there is overlapping bedrock outcrop data from this reference and the BGOC83 file, the polygons from the BGOC83 file are presented on Plate III. The source of this information is:
