2023 Map of Rocky Hill

About this map

Sourland Mtn defines the western terrain of this central New Jersey landscape, giving way to a network of creeks and brooks that feed the Millstone River corridor. The contemporary layout of Hillsborough and Princeton frames a region where colonial-era crossroads like Blawenburg and Harlingen remain central to the local geography. Significant water infrastructure is visible in the east, where the Delaware and Raritan Canal and the Main Canal run parallel to the river, a remnant of nineteenth-century transport patterns adapted for modern utility.
