A Historical Perspective by Fred Noon

300 BC to 1400 AD - Area inhabited by Hohokam Indians.

1400 - The O'odham (Pima and Tonono) Indians, possibly descendants of the Hohokam, occupied the valley for many years, and named the area; "Ari" (Ali) means "little," "vaca" (wahia) refers to a place where water comes up.  Early Spaniards recorded the name as Aribac.

Recorded History - 1695 - Father Kino, missionary and explorer, traveled through Aribac and included the visita of San Martin de Aribac on his map of Pimeria Alta.
