The Mississippi River today is a classic meandering river. 20,000 years ago the Mississippi River was a major outwash channel fo

r the Laurentide ice sheet, and was characterized by dramatic variations in flow with huge discharge during summer ice melt and a dramatic falloff in discharge during the winter. The river also carried coarser sediment than today, with abundant sand and even gravel in its upper reaches. What does this suggest about the ancient Mississippi?
