Black diamond Ski Granby, CO
South Forty drops 402 vertical feet over 2,357 feet of skiing, with a steepest pitch of 24° about 1,220 feet below the top. That's steeper than 21% of the 4,740 black diamond runs we've measured in North America, and the 4th steepest of 42 named runs at Ski Granby. It faces east.
Facing east at an average 10°, South Forty gets about 103% of the winter sun that flat ground at Ski Granby does, December through March. That's sunnier than 74% of the runs we've measured, and the 3rd sunniest named run at Ski Granby. Its top sits at 9,050 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.
