Legend has it that some of Minnesota's 10,000 lakes formed in the footprints of Paul Bunyan's blue ox, Babe. Actually, there are over 15,000 lakes in the state, and many of them formed during the last Ice Age--when glaciers moved back and forth across most of Minnesota. In places, particularly those near ice margins where a lot of sediment was being deposited, large fragments of ice could become buried under layers of dirt. The buried ice would eventually melt and the dirt collapse leaving holes, called kettles, in the ground. The kettles filled with water to become lakes. Areas of Minnesota where a lot of lakes occur may mark the edge of an ice sheet

During the most recent ice age, Minnesota was covered by a huge glacier. As it moved, it gouged out huge pockets out of the earth, which later filled with water. Many lakes in the north were caused from glacier activity

The lakes were already there, when the white
settlers drove the Indians off of the land and then drew the maps of the land into states, to distribute the land amongst themselves.

It was once the bottom of the ocean and the land is very low lying. The saltwater has been replaced by rainwater.

probably has something to do with the ice ages and glaciers left behind.
