Black diamond Pebble Creek, ID
Backdoor drops 233 vertical feet over 572 feet of skiing, with a steepest pitch of 30° about 160 feet below the top. That's steeper than 60% of the 4,740 black diamond runs we've measured in North America, and the 14th steepest of 46 named runs at Pebble Creek. It faces west.
Facing west at an average 24°, Backdoor gets about 102% of the winter sun that flat ground at Pebble Creek does, December through March. That's sunnier than 73% of the runs we've measured, and the 8th sunniest named run at Pebble Creek. Its top sits at 8,480 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.
