Aymara indigenous women walk toward Huayna Potosi mountain, Bolivia April 6, 2016. Two years ago, about a dozen Aymara indigenous women, aged 42 to 50, who worked as porters and cooks for mountaineers at base camps and mountain climbing refuges on the steep, glacial slopes of Huayna Potosi, an Andean peak outside La Paz, Bolivia, put on crampons under their wide traditional skirts and started to do their own climbing.
