A Series of Rock Piles Oct 14 2017

This is series of unique rock piles running along a ridge in a northerly direction , regularly spaced so that as you walk you can anticipate where the next pile will be.  They are spread out over almost 3/4's of a mile.  I expect if I had more time and a few less years, I could follow them for several more miles.  It appears that they have been knocked about over the years, and are buried in woodland debris. They may not be in the exact order.
