This image may or may not show a solar calendar. Sometimes spiral images are used to designate the arrival of an equinox or solstice. Other times the represent a journey or the entrance to the underworld. But when I saw the alignment of this spiral with the large boulder sitting on the ledge above it I began to suspect that perhaps the shadow cast by the large rock might intersect the center of the spiral, or the prominent ending point, or both, at one of the seasonal extremes. Perhaps the Park Service or archaeologists have observed this location on appropriate dates and would have information as to the validity of my assumption.
At any rate, it is interesting that the spiral has been pierced by the crack in the rock on which it was created. |
