Black diamond Kirkwood, CA
Sunnyside drops 312 vertical feet over 1,198 feet of skiing, with a steepest pitch of 26° about 760 feet below the top. That's steeper than 30% of the 4,740 black diamond runs we've measured in North America, and the 38th steepest of 58 named runs at Kirkwood. It faces southeast.
Facing southeast at an average 15°, Sunnyside gets about 129% of the winter sun that flat ground at Kirkwood does, December through March. That's sunnier than 92% of the runs we've measured, and the sunniest named run at Kirkwood. Its top sits at 8,950 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.
