The Allegheny River (historically, especially in New York state, also spelled Allegany River) is a principal tributary of the Ohio River, which it forms with the Monongahela River at the downtown Pittsburgh's Golden Triangle "point".
In its upper reaches the Allegheny is joined from the south by Potato Creek in McKean County, Pennsylvania and from the north by Olean Creek at Olean, New York.
The conflict over the expansion of British settlement into the Allegheny Valley and the surrounding Ohio Country was a primary cause of the French and Indian War in the 1750s.
The Allegheny Plateau is a large, dissected plateau area in southern New York, western Pennsylvania, West Virginia, and eastern Ohio.
The plateau terminates in the east at the Allegheny Mountains, which are the highest ridges just west of the Allegheny Front.
In the unglaciated Allegheny Plateau in southeastern Ohio and westernmost West Virginia, relief is typically in the range of two hundred to four hundred feet.
