Short description:
Sinkhole Areas and Sinking-Stream Basins, 1997 (1:126,720) - Shows sinkhole areas (SHA) and sinking-stream basins (SSB) associated with rocks of Silurian, Devonian, and Mississippian age in southern Indiana. Shows sinkhole areas larger than 80 acres. Some sinkholes may exist outside the delineated areas, and some sinkholes may exist within the areas designated as sinking-stream basins, but such areas are not shown in this layer. The data should not be used for site-specific data analysis. The layer was compiled from unpublished work maps of Richard L. Powell and was used in the creation of the following published maps: Indiana Geological Survey Miscellaneous Maps 64 and 65.
