Gene Reardon's Run drops 458 vertical feet over 1,605 feet of skiing, with a steepest pitch of 28° about 1,230 feet below the top. That's steeper than 90% of the 5,615 blue runs we've measured in North America, and the 100th steepest of 139 named runs at Aspen Mountain. It faces northeast.
Facing northeast at an average 17°, Gene Reardon's Run gets about 63% of the winter sun that flat ground at Aspen Mountain does, December through March. That's shadier than 81% of the runs we've measured, and the 37th shadiest named run at Aspen Mountain. Its top sits at 9,900 feet.
Shaded snow stays colder and drier, so it holds powder longer after a storm and is slower to crust over or turn to slush in spring. Shading from ridges and trees isn't counted yet.
