Korona Peak
Uchitel glacier and Korona ridge area · Chuy Region · Kyrgyzstan
ELBig alpine day. Long mandatory section, non-trivial retreat or descent; a pacing or line mistake can already push you into darkness.
There are isolated dangerous spots, but they are short or well controlled by start time and line choice. The risk is usually clear and local.
Generally controllable, but with gaps, awkward placements or isolated sections where the consequences can be unpleasant.
3 sections · 250 m
Ice up to about 50–60° without a distinct technical problem; basic crampon and tool skills are needed.
Without an angle, AI1–AI2 are counted with reduced confidence.
For AI1–AI2 a grade alone often isn't enough. If the ice isn't steep, the angle matters: 20°, 40° and 60° are very different terrain.
