I found this website, it has some of the more unusual ski areas around the world.

Also this week in Colorado...Friday at Keystone is the 36 hours of Keystone. Its a skiing marathon. Most people get a team together and rotate by the hour who is skiing, who is partying and who is sleeping. Its alot of fun.
Also this weekend is the US stop on the world cup circuit at Beaver Creek. If you have never been to such an event, it definitely has a european feel, and to see the downhill in person really puts watching it on TV a shame. You really don't get an appreciation of the speed involved or how steep the course really is. I love skiing the course immediately after the downhill, its the one time a years its groomed. After that its volkswagon sized bumps all the way down.
