In Manitoba, there is the Assiniboine River ...

To the south lies the Assiniboine and Souris River valleys, which were once covered by Lake Souris, which may have been a bay off of Lake Agassiz.

The range is intersected by three rivers, whose valleys divide the range into four distinct sets ...

The largest of all the proglacial lakes was Lake Agassiz, a small part of which occupied the present Red River Valley of Minnesota and North Dakota. Glaciers to ...
Lockhart Phase of Lake Agassiz approximately 11,500 years ago when the Pembina Escarpment was formed. The area north of the orange line was the Laurentide Ice Sheet. The Pembina Escarpment is a scarp that runs from South Dakota to Manitoba, and forms the western wall of the Red River Valley. The height of the escarpment above the river valley ...
