Olentangy Indian Caverns
Delaware County, Ohio
Limestone passages cut by an underground river and used for shelter by Wyandot people, opened as one of Ohio's first roadside attractions when a farmer's ox fell through the roof. It is a fair specimen of the era when every cave in America got a ticket booth.
That was 1 of the hidden places.
Location: documented spot
