Large Rock Pile - Mason NH

Reader and neighbor Carol M writes:

This is a large rock pile in the back of George XXXs home. It roughly is about 20 x25 feet. One end is well built, and contiguous with a wall.There is also a wall traveling from the pile towards a swamp where is ends. There appears to be two hollows in the rock piles, and several areas where there is white quartz embedded.In the area are many walls, with Indian like features, for example the long slab with several smaller rocks lined up on it, and rock slabs at 45 degree angles with lacy holes throughout the walls. I'm sure George would be happy to show it to you if you are interested!
