Canyon de Chelly National Monument was established in 1931 in what would become one of the unique partnerships in the United States and Arizona. As a National Monument, the park would be maintained by the National Park System even though it was still owned by the Navajo Nation (typically the Federal government purchases the land). This arrangement continues to this day. Canyon de Chelly National Monument harbors not only Navajo Native American settlements but also Ancient Pueblo People. “Chelly” is an Anglicization of a Navajo word for “canyon.” One of the rock monuments in the park has been featured in several television commercials, shows, and movies.
