A former show cave in Pennsylvania that no longer offers public tours; the land is now protected for bats.
Harold Aden Wertz opened Indian Caverns in Spruce Creek to visitors in 1929, with tours that mixed limestone formations with Native American artifacts and stories in the roadside-attraction style of the time. Public tours ended in October 2016, and the property was later acquired for conservation to protect the cave and its bats.
