FFC spent a lot of time this fall measuring the positions of features out behind his house. There are lots of alignments, including stone walls that run in the direction of the winter solstice sunrise. Here is a map of the locations:This map covers about 1/4 mile edge-to-edge. I believe the diagonal lines of features from upper left to lower right are oriented toward the solstice sunrise. Also I should add that there are numerous rock piles all around nearby.
