Black diamond Keystone, CO
Black Hawk drops 910 vertical feet over 2,206 feet of skiing, with a steepest pitch of 32° about 1,650 feet below the top. That's steeper than 69% of the 4,740 black diamond runs we've measured in North America, and the 21st steepest of 140 named runs at Keystone. It faces west.
Facing west at an average 25°, Black Hawk gets about 102% of the winter sun that flat ground at Keystone does, December through March. That's sunnier than 74% of the runs we've measured, and the 42nd sunniest named run at Keystone. Its top sits at 11,230 feet.
With little slope to hide behind, it takes nearly the full winter sun of open ground: powder settles and turns heavy sooner after a storm, and spring snow softens early. Shading from ridges and trees isn't counted yet.
