Black diamond Keystone, CO
Nuchu drops 1,301 vertical feet over 4,452 feet of skiing, with a steepest pitch of 29° about 3,510 feet below the top. That's steeper than 49% of the 4,740 black diamond runs we've measured in North America, and the 36th steepest of 140 named runs at Keystone. It faces southwest.
Facing southwest at an average 17°, Nuchu gets about 131% of the winter sun that flat ground at Keystone does, December through March. That's sunnier than 93% of the runs we've measured, and the 13th sunniest named run at Keystone. Its top sits at 12,230 feet.
Angled toward the low winter sun, it bakes: powder turns heavy soon after a storm, and in spring it softens early in the day and refreezes hard overnight. Shading from ridges and trees isn't counted yet.
