Mississippi River

The Upper Mississippi from below St. Anthony Falls [1] (Minneapolis [2], Minnesota [3]) downstream to St. Paul, Minnesota is a gorge [4] with high limestone bluffs carved by the waterfall. Upstream of the waterfall the land slopes gently to rivers edge. Downstream of downtown St. Paul the river enters its wide preglacial valley.[wikipedia]
