We had a great day today. Beautiful topography and "other worldy" vegetation. We did the classic mountaineering "climb high sleep low" practice today. Reached 15000ft our highest point so far and then descended to 13000ft to sleep. The group is all in good spirits though some are suffering expected headaches and nausea. However, we are confident after a good meal and sleep we will all be ready for morning ascent of the barranco wall. Lala Salama (good night).
