Double black Aspen Mountain, CO
Bonnie Bell drops 272 vertical feet over 496 feet of skiing, with a steepest pitch of 38° about 390 feet below the top. That's steeper than 59% of the 2,251 double black runs we've measured in North America, and the 26th steepest of 139 named runs at Aspen Mountain. It faces east.
Facing east at an average 33°, Bonnie Bell gets about 97% of the winter sun that flat ground at Aspen Mountain does, December through March. That's sunnier than 68% of the runs we've measured, and the 7th sunniest named run at Aspen Mountain. Its top sits at 9,090 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.
