Black diamond Big Sky, MT
Gun Mount drops 320 vertical feet over 1,152 feet of skiing, with a steepest pitch of 23° about 330 feet below the top. That's steeper than 14% of the 4,740 black diamond runs we've measured in North America, and the 202nd steepest of 290 named runs at Big Sky. It faces east.
Facing east at an average 16°, Gun Mount gets about 98% of the winter sun that flat ground at Big Sky does, December through March. That's sunnier than 70% of the runs we've measured, and the 112th sunniest named run at Big Sky. Its top sits at 9,140 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.
