The Cuyuna Iron Range is a former North American iron-mining district about ninety miles west of Duluth in central Minnesota.

After mining peaked in 1953, the district began to focus on non-iron-mining activities in order to remain economically viable.

Charles A. Lindbergh, a native of Little Falls, became a world-famous aviator after completing the first nonstop, solo transatlantic flight in May 1927.

Since the early 1900s, Latinos have been a productive and essential part of Minnesota. Most of the earliest Minnesotanos were migrant farm workers from Mexico or Texas and faced obstacles to first-class citizenship that are still being addressed.

Latinos faced, and still face, discrimination—both racial and the kinds common to all immigrants, migrants, and refugees.
