The confluence of Laurel Hill Creek, the Casselman River, and the Youghiogheny River forms the geographic heart of this Somerset County landscape. The town of Confluence serves as the focal point for this hydraulic intersection, situated just north of the expansive Youghiogheny Lake. This mid-1990s record details a region shaped by both its natural waterways and substantial transportation infrastructure, including the National Road running through Addison and several rail tunnels like Brooks Tunnel and Shoofly Tunnel.
