Black diamond Pebble Creek, ID
Upper Green Canyon drops 522 vertical feet over 1,199 feet of skiing, with a steepest pitch of 29° about 510 feet below the top. That's steeper than 48% of the 4,740 black diamond runs we've measured in North America, and the 23rd steepest of 46 named runs at Pebble Creek. It faces west.
Facing west at an average 26°, Upper Green Canyon gets about 98% of the winter sun that flat ground at Pebble Creek does, December through March. That's sunnier than 70% of the runs we've measured, and the 11th sunniest named run at Pebble Creek. Its top sits at 8,320 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.
