 The mining of cinnabar at the Kornock can already be proven in the 17th century.A former stone pit at Lake Turrach, as well as a magnesium carbonate and a slate pit, are evidence of the mining activities around Turracher Höhe, which however were entirely given up in the course of the 20th century for economic reasons.In the 19th century, the first housing was built on the pass summit at the Turracher Lake.
