Black diamond Deer Valley, UT
Ontario Bowl drops 154 vertical feet over 561 feet of skiing, with a steepest pitch of 23° about 430 feet below the top. That's steeper than 15% of the 4,740 black diamond runs we've measured in North America, and the 140th steepest of 224 named runs at Deer Valley. It faces northwest.
Facing northwest at an average 16°, Ontario Bowl gets about 68% of the winter sun that flat ground at Deer Valley does, December through March. That's shadier than 75% of the runs we've measured, and the 50th shadiest named run at Deer Valley. Its top sits at 8,950 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.
