From Ted Hendrickson:
We were walking in the Audubon Preserve in Montville recently, right next to the area we visited on Beaverdam Hill last fall. Lots of cairns on boulders and a surprising little valley/hollow with rock constructions aplenty. While some encountered seemed like they could be building piles for the many walls, the valley/hollow area didn't make sense to me as that. It was very wet and boggy. Ledges sloped into it blocking light forming a rocky frame to the scene, not a likely farming or grazing spot to my mind. An inordinate amount of piling and stacking going on.
Very intriguing collection of structures included this little collection of piles in a central location.
Lower down, a nice stack on boulder. Hmmm...
You can see some of the other piles on boulders in the background. Here is a rough panorama of the context.
My feet were sinking into the bog-like ground as I shot these images. Further up on the right of this image is the path that brings you near this valley. Just on the other side of the path a few more interesting piles with an interesting upright triangular stone.
There is an colonial foundation further on and many walls which seem to be field boundaries. However , some of the boulder cairns looked like they might be responding to the splits or structure of the supporting stone.
An interesting site that Norman has visited. I will be going back to look into reports of a larger pile deeper in the property.
