Black diamond Powderhorn, CO
Upper Thunderbird Glade drops 576 vertical feet over 2,353 feet of skiing, with a steepest pitch of 26° about 2,040 feet below the top. That's steeper than 27% of the 4,740 black diamond runs we've measured in North America, and the 21st steepest of 48 named runs at Powderhorn. It faces northeast.
Facing northeast at an average 15°, Upper Thunderbird Glade gets about 74% of the winter sun that flat ground at Powderhorn does, December through March. That's shadier than 64% of the runs we've measured, and the 19th shadiest named run at Powderhorn. Its top sits at 9,770 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.
