A petrographic study of Gila Polychrome 

Gila Polychrome pottery has been recognized since the time of the earliest archaeological work in the Southwest. Cushing, in 1887–88, recognized in the polychromes at Los Muertos and other Classic period sites of the Hohokam area the pottery type we now call Gila Polychrome. As more of the Southwest became known this type (W. and H. S. Gladwin 1930: 6) was found to be one of the most widespread, with a range extending from the Mogollon Rim on the north into northern Chihuahua and Sonora on the south and sporadically from Texas on the east through New Mexico to Gila Bend, Arizona, on the west (Haury 1945: 63).
