Pia Oik, Arizona
It's a small village of Tohono O'odham Nation. It's located 9.0 miles north of Ali Chuk and 8 miles south of Gu Vo. Below is a google earth map of Pia Oik. I do not know what Pia Oik's population is. It is not an incorporated settlement. Using google earth i counted about 15 housing units in Pia Oik. Anywhere from 10 to 15 are lived in. I would estimate Pia Oik's population to be between 30 and 50. Pia Oik does not have an appearance of a town. It's more rural. Housing units are scattered over a rather small area. There is either a lake or dry lake about 1/4 of a mile northeast of this Papago Reservation settlement.
