Black diamond Arizona Snowbowl, AZ
Upper Volcano drops 671 vertical feet over 1,701 feet of skiing, with a steepest pitch of 29° about 860 feet below the top. That's steeper than 47% of the 4,740 black diamond runs we've measured in North America, and the 10th steepest of 50 named runs at Arizona Snowbowl. It faces northwest.
Facing northwest at an average 24°, Upper Volcano gets about 64% of the winter sun that flat ground at Arizona Snowbowl does, December through March. That's shadier than 80% of the runs we've measured, and the 5th shadiest named run at Arizona Snowbowl. Its top sits at 11,490 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.
