Aberdeen Proving Ground dominates the eastern half of this landscape, reflecting a century of military integration into Harford County. The map details the specialized infrastructure of this installation, including the Phillips Army Airfield and the tactical grid of Trench Warfare Range Rd. Scattered along the edges of the military reservation are older civilian footprints like Michaelsville and Old Baltimore, which stand in contrast to the developed residential clusters of Riverside and Edgewood.
