Blue Big Sky, MT
Sunlight drops 551 vertical feet over 2,500 feet of skiing, with a steepest pitch of 21° about 2,050 feet below the top. That's steeper than 48% of the 5,615 blue runs we've measured in North America, and the 218th steepest of 290 named runs at Big Sky. It faces south.
Facing south at an average 13°, Sunlight gets about 133% of the winter sun that flat ground at Big Sky does, December through March. That's sunnier than 94% of the runs we've measured, and the 40th sunniest named run at Big Sky. Its top sits at 8,990 feet.
Angled toward the low winter sun, it bakes: powder turns heavy soon after a storm, and in spring it softens early in the day and refreezes hard overnight. Shading from ridges and trees isn't counted yet.
