Black diamond Sun Valley, ID
Sunnyside Bowl drops 779 vertical feet over 1,855 feet of skiing, with a steepest pitch of 31° about 260 feet below the top. That's steeper than 66% of the 4,740 black diamond runs we've measured in North America, and the 19th steepest of 99 named runs at Sun Valley. It faces east.
Facing east at an average 25°, Sunnyside Bowl gets about 102% of the winter sun that flat ground at Sun Valley does, December through March. That's sunnier than 73% of the runs we've measured, and the 19th sunniest named run at Sun Valley. Its top sits at 8,190 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.
