The Ring Quarry in Vernon is a prehistoric mining district in Vernon. At the Ring Quarry, the native peoples found the raw materials, known as chert or flint, to manufacture spear points and tools. This chert from the Ring Quarry is found in the form of manufactured points and prehistoric tools throughout the township at other Native American sites such as the Black Creek Site. The Ring Quarry is evidence that native people found the raw materials for their tools right here in the township. The Ring Quarry was nominated for inclusion on the New Jersey and National Registers of Historic Places.
