Neutron activation analysis was carried out on 60 Dogoszhi style black-on-white ceramic vessels from three prehistoric Chacoan sites in the northern U.S. Southwest. Cylinder vessels and bowls from Pueblo Bonito and Pueblo del Arroyo, two large towns located in Chaco Canyon, New Mexico, exhibited a high degree of compositional homogeneity. However, bowls from the community associated with the outlying town of Allentown were compositionally different, suggesting that they were manufactured at a different location. Comparisons with the results of neutron activation analyses obtained previously for Dogoszhi style sherds from Black Mesa, Arizona, revealed that these ceramics also were compositionally different from those found in Chaco Canyon.
