OK, this one is for ski nerds. Check out this really fun article about steep trails that I found on skibum.net. The article shares all kinds of interesting facts and trivia about comparing steep terrain. I have always thought Pallavicini was one of the longest, continiuously steep trails around. Low and behold, skibum.net had Pali at the top of the list for select trails over 2,000 feet long. Enjoy.
