Double black Copper, CO
Lallarookn drops 494 vertical feet over 1,789 feet of skiing, with a steepest pitch of 27° about 910 feet below the top. That's steeper than 15% of the 2,251 double black runs we've measured in North America, and the 63rd steepest of 141 named runs at Copper. It faces southeast.
Facing southeast at an average 16°, Lallarookn gets about 115% of the winter sun that flat ground at Copper does, December through March. That's sunnier than 83% of the runs we've measured, and the 18th sunniest named run at Copper. Its top sits at 12,330 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.
