The Navajo name of Jádító (Antelope Water) was derived from nearby watering points, which were frequently used by antelopes. Most families living within the Jeddito "island" are members of the extended families who were forcefully evicted from the old Hopi Reservation (District 6) in September and October 1944. This marked the first mass relocation of Navajos determined to be living on the wrong side of the Navajo-Hopi boundary. The portion referred to as Jeddito "island" is totally surrounded by the Hopi Partitioned Land. Another segment of the chapter's land base is part of the main Navajo reservation on the Apache County side. The "island" part is situated exclusively in Navajo County.
