sinks per quad
Map above shows the number of sinkholes in some of the TN 7.5' quadrangles. Data collected by visual inspection of online topos. A TN quadrangle is about 60 sq miles. Counting sinkholes on topo maps doesn't account for sinkhole volume (depth*area). View data on heatmap or colored quads
