Squire Boone Caverns

Squire Boone Caverns and Village is a cavern exploration attraction in Mauckport, Indiana . The park consists of a one-hour walking tour into the caverns, as well as a working pioneer village and grist mill.

The cave was first discovered by Daniel Boone and his brother, Squire Boone, as they were hiding from Indians in the late 18th century. Squire would come back later to purchase the land and live near the caves in 1808 and start a grist mill at the site. The mill is on the Indiana Register of Historic Sites and Structures and still operates today.
Squire Boone died in 1815 and, having so loved the caverns, requested to be buried in them, and was buried near the entrance to the cave. His remains were moved in the 20th century because of construction near his burial site and its continual disturbance by relic hunters. The coffin, which contained only bones, was moved deep into the caverns. The cave tour passes by the coffin and there are benches to rest and contemplate the cave and the coffin.
