The Allegheny River winds through a heavily forested corridor of the Allegheny National Forest, where river-oriented settlements like Cobham and Magee sit tucked between the water and steep valley walls. This modern survey illustrates the enduring geography of the river's eddies and islands, including Millstone Island and Fuellhart Island, which have long served as landmarks for navigation and local recreation. Away from the banks, the terrain is defined by deep cuts such as Bully Hollow and Dark Hollow, illustrating the complex drainage of the high plateau into the river basin.
