(Minnesota)
Cuyuna Country State Recreation Area (CCSRA) is a state park unit of Minnesota, USA, being developed to rehabilitate a portion of the Cuyuna Range where mining pits and piles of waste rock were left behind after decades of open-pit mining for iron ore. Abandoned by mining companies more than 20 years ago, the state recreation area consists of regenerated vegetation and clear lakes that draw a wide range of recreation enthusiasts. The park is located off Minnesota State Highway 210, near the towns of Crosby, Ironton and Cuyuna. The Croft Mine Historical Park, formerly city-run, is now part of the state recreation area.
