Black diamond Big Sky, MT
Upper Africa drops 233 vertical feet over 697 feet of skiing, with a steepest pitch of 31° about 580 feet below the top. That's steeper than 67% of the 4,740 black diamond runs we've measured in North America, and the 98th steepest of 290 named runs at Big Sky. It faces northwest.
Facing northwest at an average 20°, Upper Africa gets about 79% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 57% of the runs we've measured, and the 124th shadiest named run at Big Sky. Its top sits at 8,760 feet.
It gets an ordinary dose of sun: powder lasts a typical amount of time, and spring snow softens on a normal schedule. Shading from ridges and trees isn't counted yet.
