The Aberdeen Proving Ground Military Reservation dominates the eastern half of this landscape, reflecting its expansion during the mid-20th century. This 1948 survey, with purple revisions from 1970, captures a region defined by its strategic coastal position and rail connectivity. The Penn Central and Baltimore and Ohio railroads anchor the settlements of Perryman and Belcamp, where the terrestrial landscape meets the tidal waters of the Bush River and Chesapeake Bay.
