Blue Bridger Bowl, MT
Porcupine drops 721 vertical feet over 4,088 feet of skiing, with a steepest pitch of 22° about 3,580 feet below the top. That's steeper than 57% of the 5,615 blue runs we've measured in North America, and the 29th steepest of 46 named runs at Bridger Bowl. It faces east.
Facing east at an average 10°, Porcupine gets about 102% of the winter sun that flat ground at Bridger Bowl does, December through March. That's sunnier than 73% of the runs we've measured, and the 31st sunniest named run at Bridger Bowl. Its top sits at 7,280 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.
