United States historic place Pahaquarry Copper Mine Ruins U.S. Historic district Contributing property Part of Old Mine Road Historic District (ID80000410[1]) Designated CP December 3, 1980

The Pahaquarry Copper Mine is an abandoned copper mine located on the west side of Kittatinny Mountain presently in Hardwick Township^[2] 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.^[3]

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.^[4] 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.^[5] The earliest evidence of mining at Pahaquarry is 1740 with a brief venture funded by John Reading, Jr.^[6] 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.
