Black diamond Jackson Hole, WY
Surprise drops 529 vertical feet over 1,370 feet of skiing, with a steepest pitch of 31° about 900 feet below the top. That's steeper than 66% of the 4,740 black diamond runs we've measured in North America, and the 66th steepest of 126 named runs at Jackson Hole. It faces southeast.
Facing southeast at an average 23°, Surprise gets about 150% of the winter sun that flat ground at Jackson Hole does, December through March. That's sunnier than 98% of the runs we've measured, and the 25th sunniest named run at Jackson Hole. Its top sits at 8,220 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.
