Blue Keystone, CO
Swandyke drops 380 vertical feet over 1,356 feet of skiing, with a steepest pitch of 22° about 620 feet below the top. That's steeper than 58% of the 5,615 blue runs we've measured in North America, and the 90th steepest of 140 named runs at Keystone. It faces northwest.
Facing northwest at an average 16°, Swandyke gets about 66% of the winter sun that flat ground at Keystone does, December through March. That's shadier than 77% of the runs we've measured, and the 23rd shadiest named run at Keystone. Its top sits at 10,440 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.
