In my hunt to find things on my shoreline Ottertail county Minnesota on North Turtle Lake I have collected what I have been told by the University of Minnesota are bison bones. I broke my wrist collecting this spring so I have been reduced to looking over my finds and I noticed for the first time what looks like cut marks. I have also found various tools including a core rock. Does anyone know if these are marks made by a tool?
