StoneWorks Noted in Hopkinton State Park
These were way down the other end of the main entrance, towards the Ashland Town line. I honestly haven't explored the trails/ off the trails of this State Park much for old Native stone-works, but I did spot these the other week, by chance. I have heard though, that there are more stone-works to be seen at this state park in other parts.
Split stone w/ inserts:
And some cairns:
