The Casselman River winds through this Maryland-Pennsylvania borderlands area, anchoring a landscape where mountain ridges and deep creek valleys define the local settlement patterns. Grantsville serves as the primary hub, situated near the National Road and the Casselman River Bridge State Park. The terrain is characterized by prominent elevations such as Negro Mtn and Meadow Mountain, with the Savage River State Forest covering much of the western and southern reaches.
