The way between the township of Idar and the Vollmersbach village was going in the earlier days trough a heavily worked quarry. Sometimes, if somebody would like to pass trough, he had to wait until the rock-blasting was done and the road was save again. Today the quarry is no more working and is being land-filled.

The characteristic nodules from Volmersbach quarry show a reddish wave-shaped crust, covered with ironoxide. In the center they are showing very often carbonatic formations. Very esthetical pseudomorphic formations after aragonite could be found here - so called “explosions”.Very rare from this location are finelined banded brownish to creamy coloured agates.
