Pull into the Copper Mine parking area and follow the Copper Mine trail along the stream up the mountain. It's spectacular. You might also want to read chapters one and two of Beck's "The Roads of Home" - they discuss this area. Chapter 2 is about his search for Sunfish Pond, somewhat reminiscent of his quest for Forked River Mountain in "More Forgotten Towns": http://maps.njpinebarrens.com/#lat=41.0025083440068&lng=-75.07155418395996&z=15&type=topo&gpx=
