Best Ski State (Based on Vert)

I made a little map ranking states and their skiing.  It is based on the ski area of each state with the most vertical feet.  Each state is labeled with its name, its largest ski area (by vertical feet), and the vertical feet of that ski area.

The West is the best.  Though the Northeast has impressive numbers too.  Colorado and Wyoming have ski areas with over 4000 foot of vertical!  Places like Michigan and Wisconsin looked like good places to ski when looking at their total number of ski areas, but now they don't seem like such an ideal place for skiing.
