Why Not drops 309 vertical feet over 1,149 feet of skiing, with a steepest pitch of 28° about 520 feet below the top. That's steeper than 41% of the 4,740 black diamond runs we've measured in North America, and the 39th steepest of 69 named runs at Silver Mountain. It faces northeast.
Facing northeast at an average 16°, Why Not gets about 71% of the winter sun that flat ground at Silver Mountain does, December through March. That's shadier than 70% of the runs we've measured, and the 40th shadiest named run at Silver Mountain. Its top sits at 5,760 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.
