One important feature of the site was the way it was bordered by stone walls. I want to emphasize this here so as to be able to reference it later when I discuss a similar site in Wayland.
These walls all were fragmentary, in short connected stretches but not forming corners. Here is a not very good or accurate diagram of the walls, but I hope it gives the idea.
Here is a view of two nearby stretches of wall. Then details of each segment separately:
There were two other stretches above the site, sort of the southeastern extremity of the rock pile area. So that means walls along the western and along the southeastern edge of the site.. I am not prepared to classify this site. It seems more like a memorial site, with all the burnt rock in the piles. When I called FFC up to share my excitement about the site, and mentioned all the burnt rock, I mentioned ceremonial fires being built with rocks, and with the rocks later being incorporated into rock piles. And FFC brought up sweat lodges and the possibility that burnt rocks from the sweat lodge could have been used to make rock piles, as an extension of the activity. Also given the unusual wall stretches, I should get the compass boys out to make some measurements.
It is also noteworthy that this site is very similar to the XXX Hill site. It had at least one path running through the site and the path passes through a gap in the stretches of wall shown immediately above. Here is the trail as it passes the gap between two stretches of wall.
This is virtually identical with the entrance to the XXX Hill site. As soon as you pass the wall the rock piles begin.
