It was nice to look at new rock piles:


There were some small oval ground piles:




Perhaps the most interesting thing, to me, was a small rectangular pile on a saddle looking eastward.


Maybe it was, maybe it wasn't; but thinking about it led to a question: what would be the purpose of a stone "U"? We have a loose idea that stone "U"s are built as part of a prayer seat, a location for visions or, in this case, a place to look out at the sunrise. But what do you need a "U" for, when all you need to do is sit? An answer is suggested along the lines of that flat rock providing a "shield". Perhaps the purpose of the "U" structure was to shield the person on the inside from something in all directions except the viewing direction.
