McKees Rocks Mound, the largest mound built in Pennsylvania by Native Americans, was located about four miles south of Pittsburgh, at the confluence of Chartiers Creek and the Ohio River. Before its excavation in 1896 by Frank M. Gerrodette of the Carnegie Museum, the mound was 85 feet in diameter and 16 feet high. Today only a remnant of the original mound survives.
