Black diamond Sun Valley, ID
Upper Liftline drops 1,538 vertical feet over 4,137 feet of skiing, with a steepest pitch of 32° about 3,330 feet below the top. That's steeper than 72% of the 4,740 black diamond runs we've measured in North America, and the 13th steepest of 99 named runs at Sun Valley. It faces northwest.
Facing northwest at an average 22°, Upper Liftline gets about 48% of the winter sun that flat ground at Sun Valley does, December through March. That's shadier than 94% of the runs we've measured, and the 21st shadiest named run at Sun Valley. Its top sits at 9,030 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.
