Rio Grande cultural remains on the middle Gila River, Arizona: The Pueblo Revolt and the Eastern Puebloan diaspora

Data recovery investigations in the Blackwater area along the middle Gila River in south-central Arizona identified ceramic and lithic artifacts derived from the Rio Grande region. These remains were collected from GR-1425, which is located at the heading of the Blackwater canal system within the Gila River Indian Community. The site lacks evidence for permanent occupation, and instead only short-term habitation occurred. Extensive evidence for weapon manufacturing suggests that the temporary relocation was associated with conflict, and radiocarbon dates suggest that the cultural remains were deposited after the Hohokam Classic period ended circa CE 1450. The most parsimonious explanation for the data from GR-1425 is that a group of Eastern Puebloans temporarily moved to the middle Gila River around the time of the Pueblo Revolt in CE 1680. As a result of increased interactions of disparate populations brought together by the extensive population movements that occurred at this time, substantial changes in regional ceramic traditions occurred, and data from GR-1425 suggest the extent of these interactions was more wide-scale than previously recognized.
