Figure 1: The map at the top shows the extent of Glacial Lake Agassiz at the time of the carving of what is now the Minnesota River valley (bottom). Glacial River Warren cut the straight, deep valley across the state that is now occupied by the Minnesota River. The Le Sueur River is located at the bend in the Minnesota River valley.
