A 2009 archaeological survey on Knife Lake in the Boundary Waters Canoe Area Wilderness identified numerous sites believed to have been quarries used by early peoples for thousands of years. The sites include discarded tools quarry debris, and waste from making stone tools. The presentation will discuss the research and field work on the quarries and what they tell us about the very earliest inhabitants of what today is the BWCAW. Speakers will be Bill Clayton and Lee Johnson. Both men are Archaeologists for the Superior National Forest. The presentation, entitled Mookomaan Zaag’igan (Knife Lake) Siltstone: The Geology, Importance, Use, and Manufacture of Lithic Tools by the Boundary Waters’ First People, is sponsored by the Friends of the Boundary Waters Wilderness. It will be held at the John B. Davis Lecture Hall in the Ruth Stricker Dayton Campus Center on Macalester College on Tuesday, October 19, 2010. The presentation starts at 7:30 pm with refreshments served at 8:30 pm after questions.
