It is believed to have been used as an inhumation site by Native Americans of the Straits of Mackinac area in the 18th century.

[4] While in active use as a site for human remains, the cave was also used as a refuge in 1763 by fur trader Alexander Henry, a survivor of the capture of Fort Michilimackinac by Native Americans during Pontiac's War.

[5] Henry recalled his ordeal as follows: On going into the cave, of which the entrance was nearly ten feet wide, I found the further end to be rounded in its shape, like that of an oven, but with a further aperture, too small, however, to be explored.

After thus looking around me, I broke small branches from the trees and spread them for a bed, then wrapped myself in my blanket and slept till day-break.

This I supposed to be that of a deer, or some other animal, and what might very naturally be looked for in the place in which I was; but when daylight visited my chamber I discovered, with some feelings of horror, that I was lying on nothing less than a heap of human bones and skulls, which covered the floor!
