Natural Entrance to Lehman Caves, Great Basin National Park, Nevada
View Original Description
Natural Entrance to Lehman Caves was at this spot that, in about 1885, Ab Lehman first entered the cave that was to later bear his name. From then until 1940, when the present tunnel entrance was constructed, this natural entrance was used by people visiting the cave.
The contraption seen here, over the original entrance was built to keep people out, but to allow native bats to leave and enter the cave. Formerly designated Lehman Caves National Monument, the cave is now a part of Great Basin National Park.
