History


Description

The Johannisfelsen (John's Rock) near Usterling belongs to the so-called growing rocks, or tufa runnel. It is also known under the name Wachsender Felsen (growing rock). The lime-rich water builds its own bed and thus creates a dam over time, on the crown of which the stream flows in its self-made channel. The Johannisfelsen is not very long at 40 m long, but with a height of up to 5 m it is the highest tufa runnel in Bavaria.
