The Laurentian Ice Sheet, where now lies the Hudson Bay, had glaciations named for each geographic region: Nebraskan, Kansan, Illinoisan, and Wisconsin. Markings of these glacial events can still be seen in parts of Minnesota today in the form of striations and grooves within the ground, the irregular hilly deposits from end moraine, the high terrace created by ancient rivers, exposed bedrock, and the finely textured silt of loess found in the prairie soils. It is the geographic history that helps create the beauty and unique lands within the state of Minnesota.
