Black diamond Kirkwood, CA
Lost Cabin drops 974 vertical feet over 3,209 feet of skiing, with a steepest pitch of 35° about 160 feet below the top. That's steeper than 83% of the 4,740 black diamond runs we've measured in North America, and the 22nd steepest of 58 named runs at Kirkwood. It faces east.
Facing east at an average 18°, Lost Cabin gets about 93% of the winter sun that flat ground at Kirkwood does, December through March. That's sunnier than 63% of the runs we've measured, and the 10th sunniest named run at Kirkwood. Its top sits at 9,180 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.
