The Drava or Drave (, ; ; ; ; ), historically known as the Dravis or Dravus, is a river in southern Central Europe. With a length of (441 miles), or (450 miles), if the length of its Sextner Bach source is added, it is the fifth or sixth longest tributary of the Danube, after the Tisza, Sava, Prut, Mureș and likely Siret. The Drava drains an area of about 40,154 square kilometers (15,504 sq. mi.). Its mean annual discharge is seasonally (650 cu. yd.) per second) to (880 cu. yd.) per second.

The Eiskar is the only existing glacier in the Carnic Alps, a mountain range in Austria and Italy. It is a typical cirque glacier that, thanks to its shady location and to avalanche breaks in its catchment area, has been able to survive at the relatively low height of 2160–2390 metres above sea level. Although the ice sheet in good times could calve over a rock wall down to the pasture of Valentinalm below, currently it is rapidly becoming a sheet of dead ice. In the period 2007–2014, however, no significant retreat was observed. The glacier may be accessed from below up a klettersteig, a
