Isn't it amazing that Lindsay Vonn & Kristina Kosnick came out of Buck Hill's racing program? Not only is it a midwest bump, it's the smallest midwest bump I've ever been to.
This Pro Race was actually at Afton Alps. I skied all of the hills you mentioned when I was younger and some of them are indeed gone. Snowcrest is now a very nice golf course and the other hill very close to that (Birch Park) now has houses on it (you can still see where the runs were. Trollhaugen is alive and well - I think the snowboarders like it. Welch just opened up some new runs on their back side this year. I don't know if you ever made it up to Lutsen, but they've also grown over the years. They opened up the adjacent sawtooth mountain that has just over 1,000 vertical with some very nice long runs and one true double black on the back side that is just as steep as the double blacks out west (although obviously shorter). They didn't even put the run on their trail maps. It doesn't have a formal sign at the top, just a couple of those round blaze orange "experts only" signs at the top. Sweet.
Being from the Midwest I have headed up North to Minnesota for some skiing.

Steeplechase is in limbo right now -- it has been for sale a couple years. I think the story is (not positive) that the owner of Coffee Mill area created Steeplechase, and then passed away shortly after it opened.
