Blue Crested Butte, CO
Upper Conundrum drops 165 vertical feet over 871 feet of skiing, with a steepest pitch of 20° about 490 feet below the top. That's steeper than 41% of the 5,615 blue runs we've measured in North America, and the 198th steepest of 227 named runs at Crested Butte. It faces north.
Facing north at an average 11°, Upper Conundrum gets about 77% of the winter sun that flat ground at Crested Butte does, December through March. That's shadier than 60% of the runs we've measured, and the 62nd shadiest named run at Crested Butte. Its top sits at 9,830 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
