Hohokam Pima National Monument is a site located on the Gila River Indian Reservation. The site was excavated in the 1930's and again in the 1960's. Research showed that the site (actually an ancient Hohokam town now named "Snaketown") was inhabited from around 300 BCE to about 1200 CE and, at its peak, may have had up to 2,000 inhabitants. After the last excavations, the site was completely reburied and nothing is visible above ground.

Congress authorized the creation of Hohokam Pima National Monument on October 21, 1972 but the property is under the ownership of the Gila River Indian Reservation and they have decided not to open it to public access. There is no literature available and no visitation allowed.
