Back in the Rock Garden, I just sort of looked around.
Last Large Boulder
And the next is really a turtle head stone, with that other stone, that is of the same sort of stone, might be a foot. I peeled back the myrtle that had grown in what turned out to be a depression that looks suspiciously like turtle claws on a turtle foot (turned on it's side and a couple feet away from the head stone).
I mean they might be turtles, of course.
Because I've heard that Indians around here didn't build stone rows ...
