Blue Great Divide, MT
Topsy drops 317 vertical feet over 1,328 feet of skiing, with a steepest pitch of 23° about 520 feet below the top. That's steeper than 59% of the 5,615 blue runs we've measured in North America, and the 78th steepest of 123 named runs at Great Divide. It faces northeast.
Facing northeast at an average 14°, Topsy gets about 72% of the winter sun that flat ground at Great Divide does, December through March. That's shadier than 68% of the runs we've measured, and the 68th shadiest named run at Great Divide. Its top sits at 6,370 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.
