 It was a few more centuries before contact between Europeans and Native Americans of Minnesota could be confirmed. In the late 1650s, Pierre Esprit Radisson and Médard des Groseilliers were probably the first to meet Dakota Native Americans while following the southern shore of Lake Superior (which would become northern Wisconsin). The north shore was explored in the 1660s. Among the first to do this was Claude Allouez, a missionary on Madeline Island. He made an early map of the area in 1671.
