Fedchenko Glacier

The Fedchenko Glacier is a large glacier in the Yazgulem Range, Pamir Mountains, of north-central Gorno-Badakhshan province, Tajikistan. The glacier is long and narrow, currently extending for 77 kilometres and covering over 700 square kilometres. It is the longest glacier in the world outside of the polar regions. The maximum thickness of the glacier is 1,000 metres, and the volume of the Fedchenko and its dozens of tributaries is estimated at 144 cubic kilometres —about a third the volume of Lake Erie. ()
