About this map

Sour Land Mountain dominates the western topography of this Somerset County landscape, while the Millstone River and the parallel Delaware and Raritan Canal define its eastern edge. This postwar survey, updated in the early 1970s, documents a region defined by institutional land use and emerging infrastructure. Significant acreage is occupied by the U S Military Reservation (Belle Mead General Depot) and the sprawling New Jersey Neuropsychiatric Institute near Skillman.

Smaller settlements like Blawenburg, Harlingen, and Belle Mead are linked by the Reading railroad line, which served as a vital transit corridor for local industry and commuters. The map records several legacy sites, including the Belle Mead Sanitarium and Our Lady of Princeton Convent, alongside smaller markers of local history like the Harlingen Reform Cem. The presence of the Princeton Airfield and numerous small stream crossings such as Bedens Brook reflects a landscape transitioning from rural crossroads to a more integrated suburban and institutional network.
