Blue Keystone, CO
Oh, Bob drops 718 vertical feet over 2,840 feet of skiing, with a steepest pitch of 22° about 410 feet below the top. That's steeper than 57% of the 5,615 blue runs we've measured in North America, and the 94th steepest of 140 named runs at Keystone. It faces west.
Facing west at an average 15°, Oh, Bob gets about 92% of the winter sun that flat ground at Keystone does, December through March. That's sunnier than 62% of the runs we've measured, and the 54th sunniest named run at Keystone. Its top sits at 11,570 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.
