Excerpt from Altitudes Between Lake Superior and the Rocky Mountains The mean of these twelve determinations is almost exactly 683 feet, as given by Major Allen; and the altitudes herein noted for St. Paul and Minneapolis and the railroads radiating from these cities are thereby referred to the sea level. The probable limit of error in the heights given by the Lake Survey for Lakes Michigan, Huron, and Superior, is only a fraction of a foot; and almost equal accuracy seems to be attained in this datum of reference at St. Paul.
