This site has yielded considerable detail on cultural developments in the Flagstaff area immediately following the eruption of Sunset Crater in 1066 AD. Between 1070 and 1130 AD, a span of a little over two generations, new ideas injected into the area by immigrants from neighboring regions caused rapid change in the local culture, which gradually blended to form a new pattern of life that marked these people as distinct from others in the Southwest.
