Fedchenko Glacier

The Fedchenko Glacier (russian: Ледник Федченко; tg, Пиряхи Федченко) 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 and covering over . It is the longest glacier in the world outside of the polar regions.In the Karakoram Mountains, the Siachen Glacier is 76 km long, the Biafo Glacier is 67 km long, and the Baltoro is 63 km long. The Bruggen or Pio XI Glacier in southern Chile is 66 km long. Kyrgyzstan's South Inylchek (Enylchek) Glacier is 60.5 km in length. Measurements are from recent imagery, generally with Russian 1:200,000 scale topographic mapping for reference as well as the 1990 ''Orographic Sketch Map: Karakoram: Sheets 1 and 2'', Swiss Foundation for Alpine Research, Zurich. The maximum thickness of the glacier is , and the volume of the Fedchenko and its dozens of tributaries is estimated at —about a third the volume of Lake Erie.

Path and location

The glacier follows a generally northward path to the east of the Garmo Peak. The glacier begins at an elevation of above sea level, and eventually melts and empties into the Balandkiik River near the border with Kyrgyzstan at an elevation of . Its waters eventually feed down the Muksu, Surkhob, Vakhsh, and Amu Darya rivers into the Aral Sea.

To the west is the Academy of Sciences Range, Mount Garmo, Ismoil Somoni Peak, Peak Korzhenevskaya and the headwaters of the Vanj River and Yazgulyam River. To the south is Independence Peak and to the east Gorbunov Peak (6,025 meters). To the north is Altyn Mazar.

Discovery

The glacier was discovered in 1878, and is named after Alexei Pavlovich Fedchenko, a Russian explorer (but not discoverer of the glacier). The Fedchenko was not fully explored until 1928 by a German-Soviet expedition under Willi Rickmer Rickmers. Between 1910 and 1913 the glacier expanded and moved forward by , blocking up the Balyandlik River the following year. It continued to recede between 1928 and 1960, stopping its inflows such as the Kosinenko, Ulugbeck, Alert and several others.
