Black diamond Big Sky, MT
Highline drops 407 vertical feet over 1,130 feet of skiing, with a steepest pitch of 32° about 530 feet below the top. That's steeper than 72% of the 4,740 black diamond runs we've measured in North America, and the 92nd steepest of 290 named runs at Big Sky. It faces northwest.
Facing northwest at an average 21°, Highline gets about 72% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 68% of the runs we've measured, and the 92nd shadiest named run at Big Sky. Its top sits at 9,020 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.
