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.
Virginia's rivers don't run due east, straight from the mountains to the Atlantic Ocean. Some run north, others flow west... and all change direction often. The bedrock in different physiographic provinces and specific locations varies in resistance to the power of the water to erode a channel.
