Black diamond Terry Peak, SD
Inferno drops 161 vertical feet over 493 feet of skiing, with a steepest pitch of 27° about 180 feet below the top. That's steeper than 38% of the 4,740 black diamond runs we've measured in North America, and the 4th steepest of 26 named runs at Terry Peak. It faces east.
Facing east at an average 19°, Inferno gets about 92% of the winter sun that flat ground at Terry Peak does, December through March. That's sunnier than 63% of the runs we've measured, and the 5th sunniest named run at Terry Peak. Its top sits at 6,210 feet.
With little slope to hide behind, it takes nearly the full winter sun of open ground: powder settles and turns heavy sooner after a storm, and spring snow softens early. Shading from ridges and trees isn't counted yet.
