Between Standish Lane and Ter Huen Dr at the western edge of Beebee Woods, there is a short stretch of stone made mostly from smaller cobbles. The path goes right through it and I think I noticed it before when I entered the woods from this direction. I am pretty sure this is not a standard colonial wall. This was next to a split-filled rock (see black swallowtail wings, below) and I am suspicious of all stonework in Beebee woods.
[I find that the correct spelling is Beebe Woods]
