The confluence of Laurel Hill Creek, the Casselman River, and the Youghiogheny River Lake forms the geographic heart of this Somerset County landscape. The 1973 revisions to the earlier 1967 survey highlight the transport-driven growth of Confluence and Ursina, where the Baltimore and Ohio railroad weaves through complex topography, utilizing the Shoofly Tunnel and Bedford Tunnel to navigate the high ridges.
