Black diamond Lookout Pass, ID
Thunderbird drops 1,105 vertical feet over 4,209 feet of skiing, with a steepest pitch of 27° about 930 feet below the top. That's steeper than 33% of the 4,740 black diamond runs we've measured in North America, and the 17th steepest of 49 named runs at Lookout Pass. It faces southeast.
Facing southeast at an average 15°, Thunderbird gets about 121% of the winter sun that flat ground at Lookout Pass does, December through March. That's sunnier than 87% of the runs we've measured, and the 11th sunniest named run at Lookout Pass. Its top sits at 6,150 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.
