Between 1988 and 1990, Ethos Consultants Ltd. completed a study of stone features at the Oldman River Dam for Alberta Pubic Works.  During that time, a total of 19 sites that were located on the rims, walls, and floors of the Oldman, Castle, and Crowsnest River valleys were examined.  These sites contained a total of 272 stone circles, 14 cairns, 11 stone alignments, 1 effigy, and 1 large buried camp.  A total of 834.91 square meters were excavated and 191,305 pieces of cultural material were collected.  More than half of this excavation was concentrated on the buried camp (DjPm-115), a Late Prehistoric/Proto-Historic winter campsite.
