Wow. I was curious about the pitch of the Lhotse Face. I found this on
PBS.org:
The Lhotse Face
The expansive western flank of Lhotse is called the Lhotse Face and is an unavoidable part of the traditional southeast route up Everest. Camp III sits about halfway up this ascending wall of glacial blue ice. From its bergshrund (base) to the top, the Lhotse Face rises some 3,700 feet, at 40 and 50-degree pitches with some occasional 80-degree bulges. The entire route is fixed with ropes, and climbers must get into the rhythmic movement of pulling and stepping up. Kicking steps, while lodging one's front points into the hard blue ice, is the predominant movement required for this unrelenting ascent up towards the South Col.
