Minnesota today is full of fascinating animals in water, land, and air. We have plentiful walleye, mysterious Canada lynx, and majestic bald eagles – to name a few. But what about the creatures that once roamed this land long before humans? There is evidence that millions of years ago, when the state was covered by a long and ancient seaway, dinosaurs stomped the lands of northern Minnesota. Today, you can still visit the mystical place where the last Minnesotan dinosaur fragment was discovered.

Hill Annex Mine State Park is a fascinating look at Minnesota's mining history. You'll find it on the Iron Range of northern Minnesota, in the small town of Calumet.
