Spring Leftovers IX
Despite all my searching I've found jack shit about this particular stone ("stane" if you want to be all Scottish). It looks too small to be a cattle rubbing stone, and it didn't appear to have any neighbors. (If you look closely you can see the homestead ruins which align PERFECTLY with the stone.)
I don't know if it's the very last remnant of a stone circle (this area of Scotland is supposed to have the highest number of stone-based Neolithic monuments, but a HUGE percentage have been lost - some farmers left the stones in place, others dismantled circles completely and tossed the stones away), or if it's an ancient marker.
