Van Buskirk Island, a man made island, lies at the heart of the valuable Hackensack River resource. The island did not exist until 1802, and was created by the dams for the mills, The Southern End was known as the old Dock, Upper Landing or Old Landing and was the official Head of Navigation on the
Hackensack River (the highest point of navigable water on the river). Schooners plied the river regularly between Old Dock and New York. The land was also an industrial center from Pre-Revolutionary War times with several types of mills: saw mills, bark mills and finally a grist mill.
