Warren County was the site of several saltpeter mines. Saltpeter is the main ingredient of gunpowder and was obtained by leaching the earth from several local caves. Henshaw Cave on Cardwell Mountain (now part of Cumberland Caverns) was a relatively small mining operation. Hubbards Cave, near Camp Woodlee, however, was a major operation. Solomon Saltpeter Cave on Ben Lomond Mountain was another relatively small mining operation. Most saltpeter mining occurred during the War of 1812 and the Civil War.
