Look for petroglyphs as you wander among the ruins. More are found nearby at Tsankawi, a detached unit of the monument. Pictographs are found in the backcountry at a site called Painted Cave. The ancient people revered this cave as a shrine and some of their descendants still do. They made the rock art and paintings in red, white and black virtually cover the entire back wall.
Access is difficult and somewhat risky.
By July 4th, the supernova was visible in broad daylight as it was the brightest object visible from the Earth besides the Sun and Moon. It remained visible by day for 23 days, and by night for 653 days. Japanese and Chinese records contain the most detailed accounts of this spectacular astronomical event. Chaco Canyon was a thriving community at that time and this early morning event would not have been missed. The Supernova Pictograph panel, near the ruins of Pe asco Blanco, consists of a star image, a crescent moon and a human handprint.
