Not surprisingly, I found row cairns with some very interesting features. My thoughts about who constructed them and for what purpose were obscured by a few things.
Niches or fence rail holes?
Manitou stones or just plain old field clearing stones that settled out in that funny position?
Rock piles on boulders: Native American or a settler finding the best way to consolidate field clearing stone?
And, why on earth would someone build a cairn at the end of a stone wall? Two views:
This piqued my interest more than the others. It's short stretches of stone row above an outcrop. Ahhhh....something I can relate to (the outcrop is just off to the left):
Just below that outcrop, but above and between the row piles and stone wall, I found these interesting rock piles. Best described as two large rock piles and one cairn, here are some photos. This first is the most telling. It is a rock pile with a hollow and, dare I say, there is an opening that faces directly toward the cairn in the background. Click on the image for a better view:
Here is the second rock pile near the cairn. I did not see a hollow in this pile, but it is relatively equidistant from the cairn, but in a different direction:
A close up of the cairn:

Finally, this picture of one of the "fence post cairns" wins honorable mention. I think the snow does a nice job of framing it, naturally:
