A fieldtrip in Boxboro

David Alling showed me some sites he found in Boxborough. He is lucky to have rock piles in his own backyard:

From the remaining vertical facing and from a general impression that these piles all were slanted in the same way, I get the sense of a calenderical function. Also, other things:

 and a hint:

We also saw some piles over by the railroad, that did not photo too well. I had explored in there before but Dave found some things I missed right next to the brook.

Boxboro is a town that "never disappoints". We passed a conservation land, with rock piles you could see from the road. Off Sargent Rd at "Half Moon Meadow":

Looking at it: it seems to be a pathway leading up to the outcrop, and then along it. Thanks David.
