The Supernova Glyph in Context

One of the most famous sites in Chaco Canyon is "The Supernova Petroglyph"
(or pictograph, depending upon whom you ask). Most photographs of the glyph
zoom in tight to show a crescent Moon, a handprint, and a painted star.
What gets lost in a close-up is here made dramatic: the glyph's maker placed
it under an overhang some distance up a cliff. Up top is the great house
Penasco Blanco.

Is this a record of the outburst of a supernova just north of Orion on July 3,
1054? The next morning, July 4, 1054, the exploding star would have risen
beside the crescent Moon and blazed many times brighter than the brightest star
or planet. If you were a Sun-watcher standing here, waiting for the dawn, and
got that for a surprise, wouldn't you take a snapshot?
