Clefts and fissures in granite gneiss. The opal variety forcherite was found here for the first time in the 1860s as thick yellow to orange crusts on gneiss.

This locality, 5 km NW of Knittelfeld, at N47.23339 E14.77555 and N 47.23365 E14.77521 is well known since the middle of the 19th century.

It takes some perseverance, patience and luck to find a nice specimen, but they are still there. It is also worthwhile to search alongside and in the creek.
