The South Branch Raritan River anchors this landscape, winding through a corridor of historic milling sites and small settlements. The river's influence is evident in the cluster of locations such as Rowland Mills, Darts Mills, Holcomb Mills, and Rockefellows Mills, reflecting an early industrial network driven by water power. To the north, the massive Round Valley Reservoir and the prominent ridge of Cushetunk Mtn define the topography, while Herr Mountain Airport sits tucked between the ridges.
