Blue Bogus Basin, ID
Troll Haven drops 214 vertical feet over 819 feet of skiing, with a steepest pitch of 20° about 240 feet below the top. That's steeper than 41% of the 5,615 blue runs we've measured in North America, and the 69th steepest of 98 named runs at Bogus Basin. It faces north.
Facing north at an average 15°, Troll Haven gets about 59% of the winter sun that flat ground at Bogus Basin does, December through March. That's shadier than 85% of the runs we've measured, and the 24th shadiest named run at Bogus Basin. Its top sits at 6,760 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
