The Susquehanna River and its archipelago of river islands define the western edge of this landscape, where industrial infrastructure and academic centers meet the water. In the early 21st century, Middletown stands as a primary hub, adjacent to the Pennsylvania State University Capital Campus. Downstream, the geography is dominated by Three Mile Island and its associated Three Mile Island Number Two Airport, situated just north of the York Haven Dam.
