Chaco Canyon is a city in New Mexico.
It was here while on a private and unofficial dig that Max Krahwinkle discovered a stone Stele with Max realizing his find could substantiate a theory archaeologists have spent decades ridiculing. Eventually, Max contacted Dr. Daniel Jackson with Daniel arriving at the site during the weekend leading up to Thanksgiving and soon confirming what Max had discovered.
According to Daniel, he also believed that dust had been invented here along with multi-story masonry and rulerstraight highways.
