Mary Jane Upper drops 237 vertical feet over 751 feet of skiing, with a steepest pitch of 25° about 460 feet below the top. That's steeper than 23% of the 4,740 black diamond runs we've measured in North America, and the 84th steepest of 164 named runs at Winter Park. It faces northeast.
Facing northeast at an average 19°, Mary Jane Upper gets about 73% of the winter sun that flat ground at Winter Park does, December through March. That's shadier than 66% of the runs we've measured, and the 55th shadiest named run at Winter Park. Its top sits at 10,850 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.
