This is the area of Southborough between Rt 9 and Gilmore Rd. The leftmost outline is a fine rock pile site with some large piles and some obvious alignments. The middle outline is along the edge of the wetland (where the first site is continued up to the head of the valley). The right hand outline is at the top of the hill, next to a landing strip. Aside from the hilltop, go in via the access road from Rt 9 and the piles are just into the woods on the right. The hilltop can be reached from Rt 9 or from Gilmore Rd.
So, if you are not from around there, go take a look. It is a fine collection of sites that may vanish. Take pictures, survey, capture what you can. But if you are from around there, get ready to help inform EMC corporation and the Town of Southborough Historic commission that they should plan their new road so as to avoid destroying valuable historic structures.
