History
The igneous hill was formed 200 million years ago when the outcrop of the Gettysburg sill intruded through the Triassic Gettysburg plain.

Early human activity included Indigenous people clearing an area on and established a burial ground about one mile southwest. prior to the 1736 British purchase of the region.Civil War
