Blue Purgatory, CO
Harris Hill Run drops 535 vertical feet over 2,572 feet of skiing, with a steepest pitch of 26° about 1,120 feet below the top. That's steeper than 80% of the 5,615 blue runs we've measured in North America, and the 49th steepest of 90 named runs at Purgatory. It faces north.
Facing north at an average 12°, Harris Hill Run gets about 75% of the winter sun that flat ground at Purgatory does, December through March. That's shadier than 63% of the runs we've measured, and the 38th shadiest named run at Purgatory. Its top sits at 10,000 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.
