Black diamond Sun Valley, ID
Lower Holiday drops 324 vertical feet over 705 feet of skiing, with a steepest pitch of 34° about 540 feet below the top. That's steeper than 80% of the 4,740 black diamond runs we've measured in North America, and the 6th steepest of 99 named runs at Sun Valley. It faces northeast.
Facing northeast at an average 27°, Lower Holiday gets about 45% of the winter sun that flat ground at Sun Valley does, December through March. That's shadier than 95% of the runs we've measured, and the 12th shadiest named run at Sun Valley. Its top sits at 7,240 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.
