I think were no glaciers back then
Glaciers had a significant impact on Minnesota's landscape by shaping its landforms, creating lakes, and depositing sediment that enriched the state's soil. Glacial activity also influenced the distribution of vegetation and wildlife in the region. Additionally, the melting of glaciers contributed to the formation of the state's rivers and waterways.

By forming valleys
yes they do and so do glaciers, hurricanes, tornadoes and many other things
~ BY MELTING, THAT CAUSES FLOODS~

The phase change occurring in glaciers is solid to solid, where water vapor or liquid water freezes into solid ice. Over time, this process of accumulation and compaction of snow forms the dense ice masses that make up glaciers.
About 1.7 percent (and falling, as many glaciers are melting due to climate change).

The Great Lakes and the Finger Lakes were carved by ice glaciation in the valleys. Lakes in Minnesota and Wisconsin were gouged out by glaciers and later filled with water from melting glaciers. Niagara falls was formed when the glaciers created dams on the rivers and changed the flow.
Glaciers changed the face of North America with the following effects:An ice sheet covered most of Canada.The southwest received heavy rains.
