In its day, the Hill Annex Mine produced over 64 million tons of iron ore that was used to make steel for steam engines, locomotives, and ships. In 1988 Hill Annex Mine became a Minnesota state park, and today you can hunt for fossils in the park or take a bus tour tracing the route miners took to get to work.
As you arrive at the Cretaceous Ore Pile, the hunt for fossils begins. Search for sharks' teeth, clams, and other oceanic fossils that formed 86 million years ago when a sea covered this area. You may keep whatever you find! Please wear old clothing, and bring drinking water. Tour runs about one and a half hours.
