We dit the route in one day from Mutnyi lake.
There was still lots of snow so we climbed the steep part direct in a good firn snow instead of roping up for the crevasses.
...Nice weather, nice climb :-)
From the lake (~3530m) ~5:15 to the summit.
Sometimes its easy to loose the path.
Steep (50°?) direct variant on the left side of the glacier. A bit scary on hard ice with only one ice axe and (improper) sport shoes (with crampons).
Down on the classic variant.
Summited from the high camp at 4200 m. No trail. The icefall has only one snow bridge which is not visible from the glacier below. Great climb in a fantastic mountain range!
