Wupatki National Monument
The Wupatki National Monument, established in 1924, preserves several prehistoric pueblos with standing architecture (including Wupatki, Wukoki, and Crack-in-Rock). Located in north-central Arizona, the monument is the only known area in the Southwest where physical evidence from at least three archeologically separate ancestral Puebloan cultures (Cohonina, Sinagua, and Ancestral Puebloan) is found together in a number of sites. Historic Navajo and Anglo ranch sites are also present. Wupatki also protects one of the few native grasslands in the Southwest not being grazed by livestock. The Doney Fault approximately divides the monument in half, with each half having distinct geology, elevation, and dominant vegetation.
Wupatki National Monument is also part of the American Southwest Virtual Museum, a digital repository of photographs, maps, information, and virtual tours.
