Blue Bogus Basin, ID
Grooming Trail drops 474 vertical feet over 3,884 feet of skiing, with a steepest pitch of 13° about 3,760 feet below the top. That's steeper than 9% of the 5,615 blue runs we've measured in North America, and the 89th steepest of 98 named runs at Bogus Basin. It faces west.
Facing west at an average 7°, Grooming Trail gets about 103% of the winter sun that flat ground at Bogus Basin does, December through March. That's sunnier than 74% of the runs we've measured, and the 24th sunniest named run at Bogus Basin. Its top sits at 6,800 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.
