Blue Heavenly, CA
Upper Perimeter drops 178 vertical feet over 1,179 feet of skiing, with a steepest pitch of 17° about 160 feet below the top. That's steeper than 21% of the 5,615 blue runs we've measured in North America, and the 108th steepest of 124 named runs at Heavenly. It faces east.
Facing east at an average 9°, Upper Perimeter gets about 95% of the winter sun that flat ground at Heavenly does, December through March. That's sunnier than 66% of the runs we've measured, and the 33rd sunniest named run at Heavenly. Its top sits at 8,880 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.
