Blue Grand Targhee, WY
Rolling Thunder drops 1,836 vertical feet over 7,185 feet of skiing, with a steepest pitch of 26° about 2,920 feet below the top. That's steeper than 83% of the 5,615 blue runs we've measured in North America, and the 53rd steepest of 83 named runs at Grand Targhee. It faces southwest.
Facing southwest at an average 15°, Rolling Thunder gets about 121% of the winter sun that flat ground at Grand Targhee does, December through March. That's sunnier than 87% of the runs we've measured, and the 24th sunniest named run at Grand Targhee. Its top sits at 9,690 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.
