The natural monument stone channel-Felsentäle, caves & Bach infiltration , short Felsentäle , located within the boundaries of the Meßkircher district Igelswies in the district of Sigmaringen in Baden-Württemberg .
The natural monument Felsentäle 2500 meters north-north-west to 1400 meters north-west of the Messkirchen district of Menningen on Igelswieser district is a small, picturesque rock gorge with caves and natural bridges. The reserve has an area of 4.1 hectares and is located in the Danube-Ablach-Platten natural area . The narrow valley, only around 300 meters long, is sunk into the overburden from the crack period and exposes the "hanging bank limestone" ( tithonium , ti1) of the White Jura ζ3 in normal and mass limestone facies ζm. These so-called sponge stumps are part of the southeastern reef formation in the former Jurassic Sea. It originated around 140 million years ago in a shallow water zone near the coast. It is very likely that the rock valley was cut into the limestone by an outflowing lake when a glacier retreated in the Rift Ice Age.
The approximately 5.5 km long Talbach flows intermittently through the rock valleys with rock formations, caves and natural bridges in a southerly direction to its confluence with the Ablach in Menningen, but mostly it seeps away north of this gorge section. The forest in the vicinity of the rock valley is extremely rich in dolines , there is also active stream infiltration, for example at the Annenbach, which tapers from the right below the forest and the protected area . Despite studies with color input in the 1980s, it has not yet been possible to determine where the water appears again. According to experts, it migrates underground to Bad Saulgau , 25 km further east , where it is extracted as thermal water.
The 60 centimeter wide and 60 centimeter high access to the Felsentalhöhle is at the level of the Talbach . The 11 meter long cave is created in the mass limestone of the Weißjura ζm. The Felsentaltor is a natural bridge two to three meters wide, five meters high and six meters long, which the Talbach flows through if it does not seep above. To the north of the rock valley gate, the one meter wide and one and a half meter high entrance to the stone channel cave opens . This 17 meter long cave ends in a fall from a sinkhole. The Felsentale was included as an FFH area in 2004 and is part of the vineyard and water bodies near Mengen and Pfullendorf . The administrative district of Tübingen has protected the Felsentäle as a natural monument with the name "Steinrinne-Felsentäle, Höhlen & Bachversickerung".
