Double black Heavenly, CA
Boundry Chutes drops 327 vertical feet over 679 feet of skiing, with a steepest pitch of 37° about 170 feet below the top. That's steeper than 55% of the 2,251 double black runs we've measured in North America, and the 15th steepest of 124 named runs at Heavenly. It faces north.
Facing north at an average 29°, Boundry Chutes gets about 36% of the winter sun that flat ground at Heavenly does, December through March. That's shadier than 99% of the runs we've measured, and the 5th shadiest named run at Heavenly. Its top sits at 8,730 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.
