Blue Aspen Highlands, CO
Thunder Bowl drops 601 vertical feet over 1,849 feet of skiing, with a steepest pitch of 26° about 920 feet below the top. That's steeper than 83% of the 5,615 blue runs we've measured in North America, and the 75th steepest of 104 named runs at Aspen Highlands. It faces north.
Facing north at an average 19°, Thunder Bowl gets about 54% of the winter sun that flat ground at Aspen Highlands does, December through March. That's shadier than 90% of the runs we've measured, and the 25th shadiest named run at Aspen Highlands. Its top sits at 8,950 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.
