Jamtalferner, Alpine glacier in Silvretta range, Austria

Jamtalferner is a glacier at the head of the Jamtal valley in the Silvretta range, in Galtür, Tyrol. In 2008 it covered 3.31 km² and lay between 2430 and 3160 m in elevation. Its meltwater forms the Jambach, which drains via the Trisanna and Sanna into the Inn. The border with Switzerland runs along its accumulation areas at the Jamjoch.

The Österreichischer Alpenverein's glacier survey service has recorded length changes of Jamtalferner for longer than the mass-balance series. Since 1988/1989 the mass balance has been measured annually on behalf of the Hydrographic Service of the Tyrol provincial water management department. The Swiss border runs along the glacier's accumulation areas at the Jamjoch.

The glacier's meltwater feeds the Jambach, but the stream is diverted across the European watershed into the Kops reservoir, so most of its water leaves the Danube basin and joins the Rhine. The ice lies at the head of the Jamtal valley, with the Swiss border running along its feeding areas at the Jamjoch.

Visitors should know this glacier sits at high altitude where temperatures remain cold even in warmer months. Sturdy footwear and weatherproof clothing are needed if you plan to approach the ice.

The glacier's meltwater, the Jambach, is captured and diverted across the European watershed into the Kops reservoir, so most of its drainage feeds the Rhine basin rather than the Danube. The ice covered 3.31 km² in 2008, between 2430 and 3160 m.
