The coordinates of deepest point are taken from the NOAA Great LakesEnvironmental Research Laboratory webpage (www.glerl.noaa.gov/, kml file Google Earth Great Lakes Tour).
The contours for Lake Superior are generated by the GMT program, not downloaded from the NGDC website because they are not available for this lake.
The color palette of the depth scale was made to be more or less similar to the color palettes used on the NGDC Lake Huron maps.

 
This map was created with GMT.
