Black diamond Bridger Bowl, MT
Upper Thunder Road drops 178 vertical feet over 471 feet of skiing, with a steepest pitch of 27° about 80 feet below the top. That's steeper than 35% of the 4,740 black diamond runs we've measured in North America, and the 16th steepest of 46 named runs at Bridger Bowl. It faces east.
Facing east at an average 22°, Upper Thunder Road gets about 98% of the winter sun that flat ground at Bridger Bowl does, December through March. That's sunnier than 69% of the runs we've measured, and the 36th sunniest named run at Bridger Bowl. Its top sits at 7,730 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.
