Double black Lost Trail, MT
B drops 229 vertical feet over 404 feet of skiing, with a steepest pitch of 54° about 160 feet below the top. That's steeper than 100% of the 2,251 double black runs we've measured in North America, and the 1st steepest of 67 named runs at Lost Trail. It faces south.
Facing south at an average 39°, B gets about 182% of the winter sun that flat ground at Lost Trail does, December through March. That's sunnier than 100% of the runs we've measured, and the sunniest named run at Lost Trail. Its top sits at 8,060 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.
