Short description:
Bedrock Surface Contours, 20140630 - Shows topographic contours depicting the elevation of the bedrock surface in Indiana, using polylines with a 50 foot contour interval. It was produced from the DEM named "BEDROCK_SURFACE_DEM_100M_IGS_IN" which was interpolated from water well and other borehole datasets with bedrock depth data. A published paper map titled "Map Showing Elevation of the Bedrock Surface in Indiana (Contours, 2016)" (Misc. Map 94B) showing these data can be obtained from the following URL of the Indiana Geological Survey: https://igs.indiana.edu/bookstore/details.cfm?ItemID=3725&Pub_Num=MM94B
