The drive traverses three distinct physiographic provinces: the Piedmont, the Ridge and Valley, and the Appalachian Plateau. Near Frederick, the rolling farmland gives way to the Catoctin Mountains, then the dramatic cuts through Sideling Hill (visible from I-68 at milepost 74) expose 340-million-year-old rock strata. Just east of Cumberland, the route enters the Allegheny Mountains, with expansive views from the Western Maryland Scenic Railroad overlooks.
