Tränenlay
Wallendorf
On the road from Bollendorf towards Wallendorf, near the Sauerbrücke bridge in Dillingerbrück, it's worth making a stop: the Tränenlay is a limestone cave worth seeing, in which lime deposits have created unusual rock formations .
The explanation for this phenomenon: when rainwater seeps through the thick sandstone layer of the plateaus, it dissolves the calcareous binder that holds the quartz grains of the rock together. Where spring water emerges from slopes and valley cuttings, but also in the banks of streams or rivers, the carbonic acid escapes from the soluble lime compound, the water evaporates and what remains is an almost pure limestone. It is called calcareous sinter or calcareous tufa. The lime sinter is deposited along the flow paths of the water and covers mosses and plant parts with a stony crust. This creates fascinating rock formations. The process of calcareous tufa formation continues, the rocks "grow" like stalactites.
The Felsenweg 2 hiking trail in the NaturWanderpark delux leads past the Tränenlay.
