We ascended the ridge between Plosky and Ostry Tolbachik from the south, camped on the ridge at 3200m (very windy!) and ascended along the ridge the next day. Descended the same day via Plosky, going round the crater clockwise.
Note, there supposed to be a bergschrund in the lower part of the ridge but in July it was filled with snow and we did not actually see it.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
