Todd,
You have shown a ski area in Minnesota called SteepleChase Ski Area but it is shown in the wrong location. It's correct location is:
44�-14'-42.51" N
92�-30'-52.79" W
If you check this location you will see what is a ski area.

Also the location of Mount Frontenac Ski Area is not quite correct. It is located at:
44�-30'-51.13" N
92�-22'-56.63" W

Thank you for taking the time to locate all of the ski areas in the US. That must have taken a lot of time and it is much appreciated.

TOM
