Ritterkopf
The Ritterkopf is a prominent mountain in Rauris, about 3 km north of the main chain of the Tauern Alps in Austria, and separates the valleys of Krumltal and Hüttwinkltal. On the mountainsides there are the sites of mineral deposits ( rock crystal, pyrite, actinolite), some of which are tourist attractions. In the Ritterkar cirque (east of the summit) gold was mined in the 16th century.
