In Seneca, Gahayanduk means "there was a fort there." In the seventeenth century, the Seneca stored thousands of bushels of dried corn in a palisaded enclosure here. This fort was burned by a French force under Governor General Denonville of Canada in 1687. An old trench still encircled the brow of the hill in the 1840s. Burnt posts of the original palisade were exposed by a washout of the east slope in 1890.
