Hill-Annex Mine State Park is a state park of Minnesota, United States, interpreting the open-pit mining heritage of the Mesabi Range. The park is located in the city of Marble, and just outside the adjacent city of Calumet, both in Itasca County, Minnesota. The park provides access to fossil material exposed by mining from the Cretaceous era Coleraine Formation.

Flora and fauna[edit]

Conservationists have grown back trees and plants to revegetate this area scarred by the effects of open pit mining. The landscape includes grouse, deer, coyotes, timber wolves, and black bears. The most impressive excitement is the return of raptors including eagles, peregrine falcons, and hawks that come back to hunt and nest in this park.
