THE IRON RANGES OF MINNESOTA - Mining History Association

"The Cuyuna iron range in east-central Minnesota is unique in the Lake Superior region because of its large manganiferous iron-ore resources. It consists of three areas--the Emily District, the North range, and the South range. Although much smaller than the Mesabi iron range to the north, the Cuyuna was a major producer of iron ore for 80 years.
