Black diamond Sun Valley, ID
Rock Garden drops 501 vertical feet over 1,408 feet of skiing, with a steepest pitch of 29° about 740 feet below the top. That's steeper than 49% of the 4,740 black diamond runs we've measured in North America, and the 42nd steepest of 99 named runs at Sun Valley. It faces northeast.
Facing northeast at an average 21°, Rock Garden gets about 69% of the winter sun that flat ground at Sun Valley does, December through March. That's shadier than 74% of the runs we've measured, and the 61st shadiest named run at Sun Valley. Its top sits at 8,190 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.
