Black diamond Sundance, UT
Marmot Gulch drops 577 vertical feet over 1,193 feet of skiing, with a steepest pitch of 40° about 870 feet below the top. That's steeper than 96% of the 4,740 black diamond runs we've measured in North America, and the 5th steepest of 66 named runs at Sundance. It faces east.
Facing east at an average 29°, Marmot Gulch gets about 97% of the winter sun that flat ground at Sundance does, December through March. That's sunnier than 68% of the runs we've measured, and the 21st sunniest named run at Sundance. Its top sits at 7,370 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.
