A detailed site report of the excavations carried out by Bison Historical Services at the stratified, multi-component Middle Pre-Contact Period site located in south-central Alberta. In 1994, a group of six elders from the Siksika Nation choose to name the site after Saahkomaapina or Boy Chief. This report provides a picture of the site’s use. Beginning around 4500 BP, the site was occupied during the Late Mummy Cave, Oxbow, Hanna and Pelican Lake phases.
