Black diamond Brundage, ID
Christmas Tree Valley drops 196 vertical feet over 1,417 feet of skiing, with a steepest pitch of 25° about 10 feet below the top. That's steeper than 24% of the 4,740 black diamond runs we've measured in North America, and the 29th steepest of 76 named runs at Brundage. It faces southwest.
Facing southwest at an average 8°, Christmas Tree Valley gets about 130% of the winter sun that flat ground at Brundage does, December through March. That's sunnier than 92% of the runs we've measured, and the 10th sunniest named run at Brundage. Its top sits at 6,930 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.
