Comments
EgPt-6: The site is on the north side of the lake in a silt-filled bedrock basin well above the present lake level. Quigg (1978a) identified a cultural component that he attributed to the Pelican Lake phase on the basis of a very fragmentary point base. The associated radiocarbon date (S-1372) is inconsistent with this attribution. Subsequent work by Newton (1991) included five backhoe tests that penetrated much deeper layers containing three cultural levels. It is not clear whether Newton's cultural level 1 is the same level that was dated by Quigg.
