Blue Copper, CO
Otto Bahn drops 291 vertical feet over 3,305 feet of skiing, with a steepest pitch of 16° about 1,920 feet below the top. That's steeper than 18% of the 5,615 blue runs we've measured in North America, and the 123rd steepest of 141 named runs at Copper. It faces south.
Facing south at an average 5°, Otto Bahn gets about 132% of the winter sun that flat ground at Copper does, December through March. That's sunnier than 93% of the runs we've measured, and the 9th sunniest named run at Copper. Its top sits at 11,850 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.
