Re: [Rockhounds] Trip Report: Up One Side and Down the Other – Phase I

[J Bryan Kramer]

One thing that I thought was interesting about Mammoth Caves is that there
was an important Potassium Nitrate extraction facility right in the outer
cave that supplied gunpowder to the US during the War of 1812 operated by
E.I Dupont. The remains of the facility are still there including wooden
piping.
