Rillito Fan site was first excavated by the Center for Desert Archaeology in the mid-1990s (Wallace 1996) and then again in 2001 (Wöcherl 2007a). Two samples of carbonized maize were recovered from pit features associated with residential structures and directly dated (Wallace 1996; Wöcherl 2007b).
