Old Pit Depths
Posted: Sep 4, 2007 12:06 pm
Some of the earliest reported pit depths for Tennessee were measured from the lip of the sinkhole, down the slope to the top of the pit, then down the pit.
These are mostly pre-1960 measurements. They give you total depth from "ground level". Not what we would consider a true pit depth today.
