Blue Aspen Highlands, CO
Thunderbowl drops 525 vertical feet over 1,980 feet of skiing, with a steepest pitch of 27° about 1,290 feet below the top. That's steeper than 89% of the 5,615 blue runs we've measured in North America, and the 71st steepest of 104 named runs at Aspen Highlands. It faces north.
Facing north at an average 16°, Thunderbowl gets about 58% of the winter sun that flat ground at Aspen Highlands does, December through March. That's shadier than 86% of the runs we've measured, and the 32nd shadiest named run at Aspen Highlands. Its top sits at 9,010 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.
