The Susquehanna River dominates this landscape, punctuated by islands like Berrier Island, McCormicks Island, and Sheets Island. The topography is defined by the dramatic ridgelines of Second Mountain and Blue Mountain, which force the river through narrow gaps. These natural corridors shaped the transportation history of the region, visible in the massive Rockville Bridge and the extensive Conrail rail lines that follow the riverbanks through Marysville and Rockville.
