The Little Yellow Truck

This photograph looks like it was taken on some other planet.  At first glimpse, it appears that we are looking at two craters on the moon, except that lunar craters are not lined with rocks.  This was down on the beach at Little Compton, RI, one of Dick's favorite places for photographs.  I was looking at the circle of rocks and then realized that it was some kind of fire pit, for a fire on the beach.  Then I saw the little yellow trick, and that seemed to complete the photograph for me.
