Black diamond Boreal, CA
Castle Peak drops 445 vertical feet over 2,029 feet of skiing, with a steepest pitch of 28° about 160 feet below the top. That's steeper than 42% of the 4,740 black diamond runs we've measured in North America, and the 10th steepest of 71 named runs at Boreal. It faces west.
Facing west at an average 13°, Castle Peak gets about 103% of the winter sun that flat ground at Boreal does, December through March. That's sunnier than 75% of the runs we've measured, and the 25th sunniest named run at Boreal. Its top sits at 7,720 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.
