Double black Lost Trail, MT
Bottle Neck drops 230 vertical feet over 398 feet of skiing, with a steepest pitch of 49° about 110 feet below the top. That's steeper than 97% of the 2,251 double black runs we've measured in North America, and the 2nd steepest of 67 named runs at Lost Trail. It faces east.
Facing east at an average 36°, Bottle Neck gets about 93% of the winter sun that flat ground at Lost Trail does, December through March. That's sunnier than 64% of the runs we've measured, and the 40th sunniest named run at Lost Trail. Its top sits at 7,920 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.
