Saltpetre Cave State Nature Preserve

The entrance to Saltpetre Cave (cave 1; 124' THC)

Saltpetre Cave State Nature Preserve encompasses a cluster of 4 cave units with a total of 7 distinct recesses. The caves are accessible with a state-issued permit from ODNR. Saltpetre Cave itself was mined for saltpetre in its past, some of which is visible on the walls at the terminus of the cave. Caves 1 and 3 contain more than 100' of passage each, making them some of the deepest recesses in the state of Ohio. These lengths are shown in the captions as THC or the total horizontal length of the cave. Cave 1 (Saltpetre Cave) can also be classified as a pillared-alcove natural arch, with the cave itself constituting the alcove.
