The Formation of Pittsburgh’s Three Rivers
The formation of Pittsburgh’s three rivers, the Allegheny, Monongahela, and Ohio, dates back millions of years. The Allegheny River begins in Pennsylvania and New York before flowing southwest. Known for its length, it stretches roughly 325 miles, contributing significantly to the region’s water system.
The Monongahela River starts in Fairmont, West Virginia, flowing northward for about 130 miles until it merges with the Allegheny River at the Point in Pittsburgh. This river’s flow direction is unusual since most North American rivers flow southward.
The merging of the Allegheny and Monongahela Rivers forms the Ohio River, which continues westward. This confluence creates a powerful waterway extending 981 miles to the Mississippi River. Our rivers’ geology and hydrology have carved out valleys, provided resources, and established essential transportation routes. The unique landscape features formed by the rivers have heavily influenced Pittsburgh’s development, industry, and cultural identity.
