Black diamond Sun Valley, ID
Lower Christmas Bowl drops 757 vertical feet over 1,885 feet of skiing, with a steepest pitch of 31° about 1,480 feet below the top. That's steeper than 66% of the 4,740 black diamond runs we've measured in North America, and the 18th steepest of 99 named runs at Sun Valley. It faces east.
Facing east at an average 24°, Lower Christmas Bowl gets about 112% of the winter sun that flat ground at Sun Valley does, December through March. That's sunnier than 82% of the runs we've measured, and the 13th sunniest named run at Sun Valley. Its top sits at 7,530 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.
