Dr. Greg Brick, Metro State University, will describe the 2004 rediscovery of saltpeter caves along the Minnesota shore of Lake Pepin. The caves were originally described by French fur-trader Pierre-Charles Le Sueur in 1700 and lost sight of for more than three centuries. Saltpeter was the most important constituent in the manufacture of gunpowder.
