The Pahaquarry Copper Mine is an abandoned copper mine located on the west side of Kittatinny Mountain presently in Hardwick Township in Warren County, New Jersey in the United States. Active mining was attempted for brief periods during the mid-eighteenth, mid-nineteenth, and early twentieth centuries but was never successful despite developments in mining technology and improving mineral extraction methods. Such ventures were not profitable as the ore extracted proved to be of too low a concentration of copper. This site incorporates the mining ruins, hiking trails, and nearby waterfalls, and is located within the Delaware Water Gap National Recreation Area and administered by the National Park Service. It was added to the National Register of Historic Places in 1980 as a contributing property to the Old Mine Road Historic District.Local tradition and several early historians recount legends of seventeenth-century Dutch miners searching for copper in the Minisink region and commencing mining operations at this location before 1650. In order to bring this ore to market, the miners are alleged to have built a 104 miles (167 km) road, the Old Mine Road linking these mines near the Delaware Water Gap with Kingston, New York. This tradition has been refuted by recent research, and it is thought the road has no connection with the mines but was built as Dutch families from New York settled the Minisink in the Eighteenth Century. The earliest evidence of mining at Pahaquarry is 1740 with a brief venture funded by John Reading, Jr. Later attempts in the middle of the nineteenth century and a renewed effort during the early years of the twentieth century were brief and likewise unsuccessful.

A 1950s proposal to construct a dam near Tocks Island across the Delaware River was met with considerable controversy and protest. Tocks Island is located in the Delaware River a short distance north from the Delaware Water Gap. In order to control damaging flooding and provide clean water to supply New York City and Philadelphia, the U.S. Army Corps of Engineers proposed building a dam. When completed, the Tocks Island Dam would have created a 37-mile (60-km) long lake between Pennsylvania and New Jersey, with depths of up to 140 feet. This lake and the land surrounding were to be organized as the Tocks Island National Recreation Area. Although the dam was never built, 72,000 acres (291 km²) of land were acquired by condemnation and eminent domain. This incited environmental protesters and embittered local residents displaced by the project's preparations when their property was condemned. After the Tocks Island Dam project was withdrawn, the lands acquired were transferred to the oversight of the National Park Service which reorganized them to establish the Delaware Water Gap National Recreation Area.
