Artifacts uncovered during a weeklong archaeological dig at Isle Royale National Park will follow St. Cloud State University grad student Sam Olson to a lab in the basement of Stewart Hall, where she’ll pore over the 150-some pieces, most of them stone chips and copper nuggets, some stone tools.
Among the most tantalizing finds: A fish scale, preserved by the copper harpoon above it.
No one’s even sure where to send the scale. Seth DePasqual, 41, in his eighth season as Isle Royale’s cultural resources manager, described it as about one-fourth the size of a dime piece. The oxygen-depriving copper likely kept the fish scale from disintegrating.
