Down on Main Street South in Woodbury Town, there is a sign by a piece of sidewalk, alongside some glacial remains still visible on the landscape, if you know how to look at what you are looking at.
Those stones are all long gone now and most of the stone rows I suspect that lined the Indian Trail, separating it from other "zones" that Native People maintained by burning, kept from spreading out of control by these stone fire breaks.
This idea comes from 19 years of observation at the Nonnewaug Wigwams section of the trail, puzzling first about the conventional wisdom that states that the stone rows or fences grew up alongside colonial roads, when they were removed from either the road itself or from the fields along the road, all in the last 350 years.
Up by the Nonnewaug Floodplain, I think a different truth is revealed as I refer to an early aerial photo from a survey of 1934 and then examine the stone rows that still remain for "cultural signs" of the Indian cultures that lived here for 10 or 20 thousand years. Those old trails have been modified from the times of the Grand Old Army of George Washington, but here and there the old trails and stone rows exist still.

Choosing the junction of Nonnewaug Road and Bethlehem Road, and zooming in on the spot to 100% magnification, I can find a stone row I'm very familiar with, having lived there for about 30 years:
