Today’s picture for you is for the Geology enthusiasts.

This is an exposed outcrop (glacially polished, no less) of the Soudan Iron formation, at the Soudan Underground Mine State Park. It is rock like this which drew the miners to the aptly titled Iron Range in Minnesota. I probably should have been a good geologist and provided something for scale, but this outcrop is not very large.
