Near Bald Hill Hopkinton

I think I have been here before but I saw more rock piles this time. 

One little site is well enough described by this video. [But man is this a lousy video. I cannot catch a break with light, camera, or video compression.]

But I was not aware (until returning the same way) that I was under surveillance. 

Wonder why there?  I seem to recall the Historic Commission in Hopkinton is rather forward thinking, perhaps they are trying to catch someone in a sacred act? You can see I surveilled them right back.
