...still out walking with FFC in northern Westford. There are the faintest of traces. It is getting much easier to notice these things; but it is no easier to interepret them when they occur in isolation and with little context. This was a walk across a gently sloping piece of oak/pine regrowth forest. A Westford Blogger drew my attention to this patch of woods and, even as they said, it is a only a couple of steps ahead of the developers. The area was logged and flagged.
A boulder with a ring of stones coming out from it. Possibly one kind of enclosure or "seat":
Some kind of gate?
A manitou stone making up part of a small feature:
A precarious wedged rock:
These all were not part of a single cluster/site but were scattered along the slope at low density.
