Wikipedia notes: Technically the beginning point of the US Public Land Survey although the actual monument is 1112 feet north of the tripoint due to the tripoint's current location under water.

Although this tripoint is now in the Ohio River, (because of a dam downstream), there is an interesting monument on the Ohio - Pennslyvania line at the side of the PA-68 (OH-39) road. The monument, together with two explanatory signs, documents a historic surveying reference point. The inscription indicates that a spot 1112 feet south of the monument, and at what at that time was the edge of the Ohio River, was the point of beginning for surveying the public lands of the United States. There, on September 30, 1785, Thomas Hutchins, First Geographer of the United States, began the Geographers Line of the Seven Ranges. The original marker, which has been long lost, was on the colonial boundary between Virginia and Pennslyvania on the north bank of the Ohio River.
