until 1810 Wyandotte Indians used the cave.
1821 discovered by J. M. Adams.
1971 Tony Oldham's visit.


Olentangy Indian Caverns was discovered by an accident. A westbound wagon train camped nearby in 1821. The ox of J. M. Adams broke loose and fell into the cave entrance.

Numerous artifacts found in the cave indicate that it was used by Wyandotte Indians for making arrows and other stone implements until as late as 1810. Hundreds of items were found when the caverns were opened, some are on display in the Museum. Most finds were made it a chamber which was logically dubbed Indian Council Room. According to the book This is Ohio by Grace Goulder, Leatherlips, the chief of the Wyandottes, was killed at the entrance to the cave by his own people.

Recent changes at the cave were the addition of gem mining, mini golf, a maze, and a petting zoo. Also the cave name was shortened to Olentangy Caverns and is now visited on self-guided tours. And there are yoga courses inside the cave.

Another tourist trap, a cave with no speleothems! The cave is formed in two beds of rock, the Upper Columbus White limestone and the Lower Dollar Blue limestone. The guide describes the cave as having "miles of passage, containing blind white fish", and Indian chiefs using the cavern for a council meeting. I do not believe a word of it.
