My team and I were able to get to Cumbre Poniente and Cumbre Sur. We went up the Arista on the far left side which we found to be more stable than the straight shot approach that we had done in the past. Seeing the state of Glaciar Ayoloco was pretty upsetting :/
Very nice view of Popo from here.
Note: Although you can stay at the Ayoloco Hut, I would recommend bringing a tent. The hut is very old and small, so you don't want to be left out in the cold with nothing to sleep in!
