About this map

The Harriman State Park wilderness dominates the northwestern landscape of this Rockland County region, where a series of water bodies including Lake Skannatati, Lake Kanawauke, and Lake Welch follow the contours of the Ramapo Mountains. These upland forests and steep ridges like Rockhouse Mtn and Jackie Jones Mtn provide a stark contrast to the dense suburban development expanding to the south and east.

The lowland corridor transitions into a complex network of residential clusters and incorporated villages. From the educational hub at Rockland Community College to the religious community of New Square, the map documents the modern footprint of Spring Valley and Wesley Hills. Long-standing landmarks like Maple Grove Cemetery and Hillside Cemetery are preserved alongside industrial-era remnants such as File Factory Hollow and the Garnerville Reservoir.
