2011 Map of Rocky Hill

About this map

Rocky Hill and its surrounding countryside are defined by the winding course of the Millstone River and the engineered path of the Delaware and Raritan Canal. This area of Somerset County maintains a character of established villages and institutional land use, with notable landmarks like the Princeton Airport and the Belle Mead Quarry puncturing the landscape. The western edge is dominated by the rise of Sourland Mountain, while a network of smaller streams including Pike Run, Beden Brook, and Roaring Brook carve the terrain between the settlements of Skillman, Blawenburg, and Harlingen. Local history is anchored by several burial grounds, including the Harlingen Reformed Cemetery and Stoutsburg Cemetery. The presence of the Skillman Dam on Sylvan Lake and various named mills like Rock Mill suggests a landscape shaped by historical water management and early industry, even as modern residential clusters begin to expand near Bloomingdale and Belle Mead.
