Black diamond Boreal, CA
The Gully drops 214 vertical feet over 686 feet of skiing, with a steepest pitch of 24° about 180 feet below the top. That's steeper than 21% of the 4,740 black diamond runs we've measured in North America, and the 24th steepest of 71 named runs at Boreal. It faces west.
Facing west at an average 18°, The Gully gets about 108% of the winter sun that flat ground at Boreal does, December through March. That's sunnier than 78% of the runs we've measured, and the 20th sunniest named run at Boreal. Its top sits at 7,610 feet.
Angled toward the low winter sun, it bakes: powder turns heavy soon after a storm, and in spring it softens early in the day and refreezes hard overnight. Shading from ridges and trees isn't counted yet.
