About this map

Sourland Mtn anchors the western edge of this Somerset County landscape, where the high ground of the Ridge Trail overlooks a network of rural settlements and waterways. The eastern boundary is defined by the historic path of the Delaware and Raritan Canal alongside the Millstone River, a corridor that shaped regional commerce long before modern suburban growth. This survey captures the area's intricate drainage pattern, from Royce Brook in the north to Beden Brook in the south, reflecting a landscape still largely defined by its natural topography.

Several smaller communities such as Harlingen, Blawenburg, and Skillman serve as focal points for local history, with numerous burial grounds like Harlingen Reformed Cem and Beekman Cem providing essential data for genealogical research. The presence of the Princeton Airport and the development around Belle Mead illustrate the evolution of transportation and land use in this part of New Jersey during the early twenty-first century.
