I went out walking twice over the three day weekend and did not expect to find much. Yesterday I succeeded in finding one rock pile (and a neighboring rock-on-rock) on the southwestern side of "Wayland Hills" - a conservation area. It was about 10 F degrees out with a stiff breeze. But in the trees, walking on a solid crust of snow, it was in fact a very nice day out. I was happy to see other cars parked at the trail head parking lot.
Here is a rock-on-rock adjacent to the larger pile shown above.
This small "site" sits at a place on the hill where you can look down a gully towards a wetland, across the road, to the southwest.
I was pretty pleased with myself for finding a rock pile. Sometimes I imagine hunting and bringing home food for the family. This rock pile is what I call a "the family will not go hungry tonight" sort of find.
