Sum of sinkhole area for sinkholes with minimum depth of 3m based on Sutherland's digital analysis. Click on cell for quadname and cumulative area (100*km2). Based on 3x3 cells over a topo quad. TN topo is about 60 sq miles, so each cell is about 6.7 sq miles (17.3 km2). Each sinkhole is represented as a point (centroid) in determining the containing cell.
