After resting for a couple of hours in a refuge, the Cholitas get up at 11:00 pm and start dressing in their traditional colored pleated skirts, called polleras. A ragbag of home-makers, carriers and tourist guides, they start climbing the glacier at midnight so as to reach the summit at sunrise. Over their woollen clothing they carry typical mountaineering equipment: helmets, crampons, ice axes, boots and leggings.
