Obsession drops 1,238 vertical feet over 3,951 feet of skiing, with a steepest pitch of 27° about 1,470 feet below the top. That's steeper than 33% of the 4,740 black diamond runs we've measured in North America, and the 28th steepest of 126 named runs at Sunday River. It faces north.
Facing north at an average 18°, Obsession gets about 55% of the winter sun that flat ground at Sunday River does, December through March. That's shadier than 90% of the runs we've measured, and the 17th shadiest named run at Sunday River. Its top sits at 2,420 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.
