Olperer
The Olperer is a 3,476 metre high mountain in the Zillertal Alps in the Austrian federal state of Tyrol. It is the main summit on the Tux Crest (Tuxer Kamm) and is often crossed in the summer as climbers transit from the Olperer Hut to the Geraer Hut. It was first climbed on 10 September 1867 along the southeast ridge (Südostgrat) by Paul Grohmann, Georg Samer and Gainer Jackl. On its north flank is the ski region known as Hintertux Glacier on the Gefrorene-Wand-Kees glacier (also called the Tuxer Ferner).
