The Gefrorene-Wand-Spitzen are two summits on the Tux Crest (Tuxer Kamm), a mountain chain in the Zillertal Alps, one of the ranges of the central Eastern Alps in the Austrian state of Tyrol. The north summit (Nordgipfel) is recorded as 3,286 metres high in the literature, but is 3,288 metres high according to the Federal Office for Metrology and Survey. The south summit (Südgipfel), by contrast, is only 3,270 metres high. The two peaks are about 300 metres apart. They appear from the north as a stubby, cone-shaped, firn-covered dome, but from the east as a forbidding, dark rock face. Sharp, prominent ridges radiate from the peaks to the northeast and southwest, along the main crest of the mountain range. The twin peaks are the highest points in the summer skiing area of the Hintertux Glacier and, since the end of the 1990s, have been accessible from Hintertux on cable cars and ski lifts; which makes them a popular destination for day trippers. The north summit was first conquered in 1867 by Dr. Berreitter, the south summit on 7 September 1872 by the brothers, Max and Richard von Frey from Salzburg.
