Tiny insects that had two antennas and a lot of legs. They were on top of the snow along the edge of a lake. At first they looked like just specks of debris on the snow, but closer looks showed that the specks were moving.
Found in a puddle of melted snow, on a tree stump and all over the ground jumping around. Wood Lice?
Saw this sitting next to the gift shop in house on the rock Wisconsin.
