Double black Powderhorn, CO
Cannonball drops 1,055 vertical feet over 3,364 feet of skiing, with a steepest pitch of 32° about 200 feet below the top. That's steeper than 32% of the 2,251 double black runs we've measured in North America, and the 2nd steepest of 48 named runs at Powderhorn. It faces northwest.
Facing northwest at an average 19°, Cannonball gets about 75% of the winter sun that flat ground at Powderhorn does, December through March. That's shadier than 62% of the runs we've measured, and the 21st shadiest named run at Powderhorn. Its top sits at 9,360 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.
