The site was studied later by other teams of specialists. In 1992 archeologist Peter L. Storck and geologistPatrick Julig led a team doing additional excavations. Drawing on new material from botany and related disciplines, they concluded that a more conservative estimate was justified, and estimated the site was almost certainly occupied 9,500 years BP by Paleo-Indians, making it significant in North American archaeology and the archaeology of Ontario. They also said that more research needed to be done.
