On the Historic Tour route about a quarter mile from the Historic Entrance is the intersection of Audubon and Little Bat Avenues.  This is a large trunk canyon passage that is about 60 feet wide and about 30 feet high. It was set up as a banquet hall with electrical lights in the early 1900’s. There was a gas generator that charged a bank of batteries to power the lights.  In the mid-1800’s cave owner Dr. John Croghan named Audubon Avenue after his friend, the famous ornithologist and artist John James Audubon. In 1838 a visitor reported seeing “tens of thousands” of bats in Little Bat Avenue. Few bats remain, but visitors still see stain on the ceiling from the bat’s feet where they roosted.
