Maricopa Journey “O’Obab Himdagi” This par 5 memorializes the long journey of the Pee-Posh (Maricopa) from the Colorado River to the union of the Gila River and the Salt River. The union of the two rivers is on the west end of the Gila River Indian Community where the Pee-Posh a Yuman Tribe reside to this day. The location of the end of the journey also symbolizes the confederation of Pee-Posh (Maricopa) and the Akimel O'Odham (Pima), each with its own separate culture and traditions.
