Tennessee's deepest sinkhole
You can mouse over the two 10m DEM grid elements in the map above to see the low point (1427.53') in Big Sink and the "least upper bound" of 1688.93', yielding a depth of 261.4' for Tennessee's deepest sinkhole.

In 2013, Chuck Sutherland used ArcMap with Spatial Analyst to characterize Tennessee's sinkholes using 10m DEM data. ArcMap confirmed that this is Tenneessee's deepest sinkhole with a depth of 260.5' Other digital data on this sinkhole:
   Area: 0.66 km2
   Perimeter: 4.08 km
   Depth: 79.4 m
   Volume: 3113525 m3
   Low: 435.1 m
   High: 514.4 m

☹ Sadly, the microsoft terraserver (MSTopo) USGS topo map server is no longer active. The MSTopo had a higher resolution topo and was the base layer for the google map above.
