I haven't been on your blog in years, maybe because I haven't seen any rock piles. I was on a hike the other day on the Walpack Ridge Trail that runs from Walpack Center to Thunder Mt. in the Walpack area of the Delaware Watergap NRA. Just thought you would might want to see them. I was on the trail from Walpack Center, the trail is the Walpack Ridge Trail marked with a red blaze. I was more then half way through I think when I looked through the woods near a stream and saw these few piles. Not sure if someone was just clearing the area.
Some years ago I contacted you with some cairns up along the Delaware on the Pa. side and one of your members went up and checked them out. (see here)
