Black diamond Castle Mountain, BC
Cinch Sluffs drops 458 vertical feet over 830 feet of skiing, with a steepest pitch of 40° about 360 feet below the top. That's steeper than 96% of the 4,740 black diamond runs we've measured in North America, and the 15th steepest of 140 named runs at Castle Mountain. It faces east.
Facing east at an average 34°, Cinch Sluffs gets about 105% of the winter sun that flat ground at Castle Mountain does, December through March. That's sunnier than 76% of the runs we've measured, and the 50th sunniest named run at Castle Mountain. Its top sits at 5,770 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.
