Three historically and culturally distinct groups in western Arizona, the Hualapai, the Havasupai, and the Yavapai, the last traditionally divided into four regional subtribes. Each community speaks a distinct variety, with the Yavapai varieties forming a well-defined dialect, although all varieties are mutually intelligible with little difficulty. Hualapai (Walapai) is spoken at the Hualapai Indian Reservation in Peach Springs by approximately 1,000 people, slightly more than half the total population. Speakers are of all ages and at least some children continue to acquire Walapai as their first language. Havasupai is spoken by more than 500 people of all ages, nearly the entire population of the village of Supai in Havasu Canyon, at the western end of the Grand Canyon. Yavapai is spoken in four small reservation communities, Prescott, Fort McDowell, Camp Verde, and Clarkdale. None of the Yavapai varieties are thriving, and most of the estimated 100 to 150 speakers (out of a total population of about 1,000) are middle aged or older.
