The confluence of the Allegheny River and Monongahela River forms the industrial and geographic heart of this region, meeting at the Golden Triangle to create the Ohio River. This landscape is defined by the dense urban corridors of Pittsburgh and McKees Rocks, where heavy rail lines follow the water's edge and bridge crossings connect neighborhoods like Esplen and the West End. The terrain's steep elevation is evident at the Mt Washington Overlook, offering a vantage point over the complex transport networks and islands like Brunot Island.
