The deeply fissured Rhône Glacier flows at about 30 to 40 m (100 to 130 ft) per year from snow fields on the slopes of the 3,383 m (11,099 ft) Tieralplistock to a point below the Furka Pass in Valais canton, Switzerland, where the ice melts in a green lake at an altitude of about 2,208 m (7,244 ft). The melt water thunders into the valley basin far below to begin the River Rhône’s 813 km (505 mi) journey to the Mediterranean Sea via southern France and the Camargue delta.
