Landforms of the Northern Plains - Fine Art Print Map

The Northern Plains are overwhelmingly a lesson in the impact of ice. Repeated glacial advances and retreats have alternated for nearly 3 million years, leaving the vast morainal deposits across the Saskatchewan-Manitoba AND U.S. borders. All were re-shaped and smoothed by outwash channels when ice blocked the present northward drainage into Hudson Bay. Its retreat reversed the course of the Red River as far south as Lake Traverse in the NE corner of South Dakota.
An earlier advance set the course of the Missouri well beyond the edge of the most recent ice limit.
