Killer Rock

In 1837, which was a particularly rainy year, the heavily soaked clay surface of the side of the Killer Rock (Gyilkos-kő - Piatra Ghilcos) slid and blocked the Bicaz Brook. The Red Lake was the result of this landslide which dammed the course of the brook.

After the landslide, the limestone mixed with clay blocked the oozing waters and the lake gradually developed. The petrified trunks of the trees which once covered the valley can still be seen. The water containing ironoxide and lime preserved these tree trunks. In clear weather the lake mirrors the red lime rocks on its margins.

The name Killer comes, according to the legend, from the fact that during the catastrophe shepherds were grazing their flocks and they were swallowed by the falling earth.
