ALLEGHENY RIVER HISTORY. Location: A river rising in north-central Pennsylvania and flowing about 523 km (325 mi) northwest into New York then southwest into Pennsylvania again, where it joins the Monongahela River at Pittsburgh to form the Ohio River.
The river is formed by the confluence of the Allegheny and Monongahela rivers at Point State Park (called the Point) in Pittsburgh, Pennsylvania. It joins the Mississippi River at Cairo, Illinois. The native Americans considered the Monongahela to be the same as the Ohio and the Allegheny as a branch.
