Prospect Park Quarry (Sowerbutt Quarry; Vandermade Quarry; Warren Brothers Quarry), Prospect Park, Passaic Co., New Jersey, USA

This First Watchung basalt traprock quarry retains its original name and is seldomly referred to by any of the owners' names. It is approximately 2 miles (3.1 km) North of Paterson. It was opened in 1901 by James A. Sowerbutt, who ran it until his death in 1916. His son-in-law, Abraham Vandermade and his son, James Vandermade, took over the operation until it was sold to Warren Brothers in 1969. In the early 1980s, Tilcon New Jersey, Inc., purchased the quarry. Mineralization has been found in the interior of pillows, in junction pockets between pillows, in veins, and within cavities of the amygdaloid. The quarry pit is currently being filled in for a future housing development.
