Welcome to the Blue Earth County, Minnesota project page!

The county is named for the Blue Earth River and for the deposits of blue-green clay once evident along the banks of the Blue Earth River.

The area of Blue Earth County was once known as the "Big Woods" and occupied by the Dakota Indians. The French explorer, Pierre-Charles Le Sueur was one of the first white people in this area, arriving where the Minnesota and Blue Earth rivers meet. There, he made an unsuccessful attempt to mine copper from the blue earth found in the area. The area remained under French control until 1803, but soon after passed to the United States in the Louisiana Purchase. [1]
