Black diamond Powderhorn, CO
Upper Wonderbump drops 428 vertical feet over 2,065 feet of skiing, with a steepest pitch of 28° about 1,930 feet below the top. That's steeper than 41% of the 4,740 black diamond runs we've measured in North America, and the 14th steepest of 48 named runs at Powderhorn. It faces northwest.
Facing northwest at an average 12°, Upper Wonderbump gets about 80% of the winter sun that flat ground at Powderhorn does, December through March. That's shadier than 54% of the runs we've measured, and the 37th shadiest named run at Powderhorn. Its top sits at 9,790 feet.
It gets an ordinary dose of sun: powder lasts a typical amount of time, and spring snow softens on a normal schedule. Shading from ridges and trees isn't counted yet.
