The Saltpeter Cave lies beyond the Natural Bridge on the pathway to Lace Falls. It forms a large hole in the canyon wall. The cave is also the work of the past's flowing water and erosion.
The contents of the cave became a valuable resource for ammunition during the War of 1812 and the Civil War 1861-65. Workmen made gunpowder from nitrates they mined and from bird and bat droppings. There are remains of the metal rail mine cart tracks leading down into the cave which is now closed.
