Blue Grand Targhee, WY
Lost Groomer drops 576 vertical feet over 1,789 feet of skiing, with a steepest pitch of 30° about 840 feet below the top. That's steeper than 96% of the 5,615 blue runs we've measured in North America, and the 25th steepest of 83 named runs at Grand Targhee. It faces south.
Facing south at an average 19°, Lost Groomer gets about 145% of the winter sun that flat ground at Grand Targhee does, December through March. That's sunnier than 97% of the runs we've measured, and the 4th sunniest named run at Grand Targhee. Its top sits at 9,570 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.
