Black diamond Solitude, UT
Grumble drops 731 vertical feet over 2,374 feet of skiing, with a steepest pitch of 36° about 80 feet below the top. That's steeper than 87% of the 4,740 black diamond runs we've measured in North America, and the 22nd steepest of 75 named runs at Solitude. It faces northeast.
Facing northeast at an average 18°, Grumble gets about 72% of the winter sun that flat ground at Solitude does, December through March. That's shadier than 67% of the runs we've measured, and the 28th shadiest named run at Solitude. Its top sits at 8,860 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.
