Chi-Town
Chi-Town is an incredibly narrow and steep N-NE facing couloir off Mount Spalding that is rarely skied. Definitely do not attempt this if you're not sure it's filled in, and beware of extreme danger from rocks and avalanches. It dumps down into the exit to Windy City, which is a much more commonly skied line.
