The Western Apache are the Apache peoples of east-central Arizona, distinct from the Chiricahua, Mescalero, Jicarilla and Lipan groups, with their own dialect, clan system and ceremonial life. Their descendants today are organised principally as the San Carlos Apache Tribe and the White Mountain Apache Tribe, and Keith Basso's earlier ethnography of the Cibecue community describes the clan and kinship structure and the religious specialists who work with particular powers.
The best known ceremony is the girls' puberty ceremony, held over four days, in which the initiate is identified with Changing Woman. It is sponsored by the family, conducted by an engaged singer, and attended by the whole community. It was suppressed under federal policy during the reservation era and is now held openly, and the atlas describes its place in Apache life without setting out its procedure.
Oak Flat, Chi'chil Bildagoteel, is the ceremonial ground where it is held for several Western Apache communities, and it sits above a copper deposit transferred for mining by a rider attached to a defence bill in 2014. Apache Stronghold has litigated against the transfer; the Ninth Circuit ruled against it sitting en banc in 2024, and further proceedings have followed since. The atlas records the matter as open rather than concluded.
