Koralpe

The Koralpe (English: Kor Alps,[1][2] German: [ˈkoːɐ̯ˌalpə, ˈkoːʁˌalpə], Slovene: Golica or Gola planina), also referred to as Koralm (German: [ˈkoːɐ̯ˌalm, ˈkoːʁˌalm]), is a mountain range in southern Austria which separates eastern Carinthia from southern Styria.

Its highest elevation (2,140 meters) is the Große Speikkogel, a popular hiking destination and also a node for military radar airspace surveillance.

In the south, in the Slovenian territory, it is contiguous with the Kozjak mountain range.

The Koralpe consists mostly of metamorphic rock, of which some parts are of considerable interest to geologists and to collectors of semi-precious stones.

Quartz and feldspar, together with the dense forests, provided the basis for a glass and porcelain industry in earlier times.
