Crosby Mine Lakes Area
Cuyuna Country State Recreation Area
Ironton, MN
Abandoned by mining companies more than thirty years ago, this area of former mining pits and rock deposit stockpiles now boasts regenerated vegetation and clear lakes that draw a wide range of recreation enthusiasts. Over the last 20 years, the landscape that was dotted with mining pits and stockpiles has changed. The deep pits are now filled with crystal clear water and a variety of vegetation now covers the area. The result is 25 miles of natural shoreline with a considerable area of forested land containing trembling aspen, paper birch, basswood, red oak, ironwood, and big-tooth aspen. The marsh areas contain bulrush, cattail and sedge. These communities provide a home for a wide variety of wildlife. The area contains six natural lakes, plus an additional 15 deep lakes that were former mine pits. Trout, northern, bass, crappies, sunfish and walleyes inhabit the area's lakes. Most of the recreation area's 5,000 acres are undeveloped. Off-highway vehicles are not permitted within the boundaries of Cuyuna Country State Recreation Area.
