Black diamond Vail, CO
Slalom Alley drops 665 vertical feet over 2,173 feet of skiing, with a steepest pitch of 30° about 10 feet below the top. That's steeper than 56% of the 4,740 black diamond runs we've measured in North America, and the 58th steepest of 194 named runs at Vail. It faces west.
Facing west at an average 18°, Slalom Alley gets about 100% of the winter sun that flat ground at Vail does, December through March. That's sunnier than 71% of the runs we've measured, and the 56th sunniest named run at Vail. Its top sits at 10,000 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.
