Little mounds of stones seem to be part of arid landscape walking trails, at least all of the arid walks I can remember.
I wonder how the scattered rocks and stones come together apparently all on their own because I have never seen anyone actually build one.
There was nothing special about this cairn over any of the other pile of rocks that apparently no one actually built. I just happened to capture this one.
