Black diamond Big Sky, MT
Old Faithful drops 286 vertical feet over 1,175 feet of skiing, with a steepest pitch of 34° about 1,080 feet below the top. That's steeper than 81% of the 4,740 black diamond runs we've measured in North America, and the 83rd steepest of 290 named runs at Big Sky. It faces north.
Facing north at an average 14°, Old Faithful gets about 65% of the winter sun that flat ground at Big Sky does, December through March. That's shadier than 78% of the runs we've measured, and the 56th shadiest named run at Big Sky. Its top sits at 8,640 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.
