Black diamond Boreal, CA
Bonanza drops 248 vertical feet over 753 feet of skiing, with a steepest pitch of 26° about 370 feet below the top. That's steeper than 33% of the 4,740 black diamond runs we've measured in North America, and the 14th steepest of 71 named runs at Boreal. It faces northwest.
Facing northwest at an average 20°, Bonanza gets about 61% of the winter sun that flat ground at Boreal does, December through March. That's shadier than 83% of the runs we've measured, and the 5th shadiest named run at Boreal. Its top sits at 7,690 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.
