[email protected] ABSTRACT The Southern Alberta Flood Investigation Program resulted in the recovery of substantial amounts of archaeological material. Excavations were conducted at highly threatened sites. The artifact assemblages recovered from these ex- cavations both support our current understanding of Alberta’s past and challenge some long-held ideas. The new in- formation supports recently conceived ideas of the Calderwood Complex, Bracken Phase, and Avonlea-Old Women’s Transition. As well, long-held notions of the Old Women’s Phase are supported. Still, the study provides substantial evidence that the protohistoric Old Women’s Phase/Blackfoot is more complex than originally believed, with a possi- ble intrusion by the Highwood Phase/Shoshone. Furthermore, there is evidence during the protohistoric Old Women’s Phase/Blackfoot for a more rapid change than previously considered from traditional to European goods.

Introduction The Southern Alberta Flood Investigation Program chaeological resource was preserved. Excavations were was initiated by Alberta Culture and Tourism in response conducted at this group of highly threatened sites, and a to a large flood in 2013 that disturbed numerous land- large amount of archaeological material and a substantial forms along the province’s rivers and creeks (Unfreed body of knowledge were produced that both support our and Macdonald 2017).
