Black diamond Schweitzer, ID
Colburn School drops 1,020 vertical feet over 3,067 feet of skiing, with a steepest pitch of 30° about 1,020 feet below the top. That's steeper than 58% of the 4,740 black diamond runs we've measured in North America, and the 46th steepest of 98 named runs at Schweitzer. It faces east.
Facing east at an average 20°, Colburn School gets about 97% of the winter sun that flat ground at Schweitzer does, December through March. That's sunnier than 69% of the runs we've measured, and the 46th sunniest named run at Schweitzer. Its top sits at 6,060 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.
