The Pima are located near Phoenix/Scottsdale, Arizona. Pottery is rare from the Pima and is often similar to Maricopa.
Mabel Sunn during a conversation with Mary Fernald, stated: "Nobody knows about Maricopa. Maricopa are always lumped together with the Pima, and they call Maricopa pottery Pima pottery. But Pima don't make pottery now." Mabel Sunn and Ida Redbird agreed that there is no meaning behind most all of the decorations. However, frogs may have symbolized rain.
All the Maricopa potters had their favorite designs and symbols, but all were free to borrow from someone else's designs. Despite the borrowing and combination of styles, many times the artist's hand is still individual enough for identification without signature.
One of the few Pima potters, Warren Oliver, has been a potter his entire life. Having watched his great grandparents, grandparents and other relatives… he learned his craft that became his trade. His clay is sourced right in his back yard of the Gila Reservation in the Estrella Mountains and his polishing tools are various stones he inherited from his great grandparents.
