Possible Hohokam record of the 1006 Supernova

CNN.com – Ancient rock art may depict exploding star – Jun 5, 2006
In 1006, an extremely powerful and bright supernova lit up the nighttime skies of Earth. It was powerful enough that the remnants of that Supernova are well known to astronomy lovers today as the Crab Nebula.
The Supernova has long since been documented by records from Europe to China, but now, a petroglyph found in Arizona might be evidence that the Hohokam, a Native American people, might be a depiction of it, based on the depiction of the petroglyph. If that’s true, this could aid in dating this and other petroglyphs, which are too recent to use something like Carbon-14 dating.
