This volume presents the results of a three-year program of archaeological research undertaken at 21 sites within the reservoir of the Oldman River Dam. Landals summarized the results of the killsite mitigation program. DjPm-116 can be considered a large, classic, communal bison jump. DjPm-80 and DjPm-126 are considered Protohistoric single-use bison jumps, and the remaining killsites are much smaller and believed to represent small group and encounter hunting. Site DjPm-24 is interpreted as the remains of a frozen meat cache
