Llanganuco lake, which is filled with glacial meltwater, is seen in Huascaran National Park in Huaraz, September 18, 2013. The nearby Pastoruri glacier is one of the fastest receding glaciers in the Cordillera Blanca mountain range according to a 2012 paper by the University of Texas and the Huascaran National Park. Peru is home to 71% of the worlds tropical glaciers, which are a source of fresh water for millions, but 22% of the surface area of Peruvian glaciers has disappeared in the past 30 years alone, according to The World Bank.
