Dock Watch Quarry

United States

Dock Watch Quarry is an abandoned trap rock quarry located on Dock Watch Hollow Road in Warren Township, New Jersey. The site was excavated from the Preakness Basalt formation of the Second Watchung Mountain, and was active from 1930 until the early 1980s. Controversies surrounding the quarry's operations led to landmark legal decisions concerning nonconforming land use in New Jersey. Today, the site is preserved as an open space, and is recognizable by a basalt cliff face 280 feet (85 m) in height.
