Double black Aspen Mountain, CO
Lower Walsh's drops 273 vertical feet over 618 feet of skiing, with a steepest pitch of 34° about 320 feet below the top. That's steeper than 41% of the 2,251 double black runs we've measured in North America, and the 54th steepest of 139 named runs at Aspen Mountain. It faces east.
Facing east at an average 26°, Lower Walsh's gets about 109% of the winter sun that flat ground at Aspen Mountain does, December through March. That's sunnier than 79% of the runs we've measured, and the sunniest named run at Aspen Mountain. Its top sits at 10,430 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.
