Today we set off for Mulas Muertas. We climbed it right from Laguna Verde. The summit of Mulas Mertas is actually a long way from the lake and extremely long day climb from there, so we only went up to the first summit on the ridge (which is still over 5500 meters). We could have climbed farther along the ridge, but it was supposed to be a rest day and we had to save our energy for Ojos del Salado. Since we were well above 5000 meters though, it made a good acclimatization climb.
Once again, it was very windy and my hat kept blowing off. We had some great views of Laguna Verde, Incahuasi, and many other volcanoes.
