They were definitely spirals, not concentric circles. Both were facing
downslope so you could see them as you climbed up the trail. They had
moss growing in the grooves, though, so I imagine they weren't done
too recently. The stones themselves were about two or three feet
across.
Spiral petroglyphs?
