The Trübbachhöhle is a gypsum cave near Marul in the Austrian state of Vorarlberg .
It is located on the southern slope of the Gronggenkopf (1978 m), on the southwestern edge of a gypsum doline landscape below the Alpe Laguz in the Marultal ( Lechtal Alps ). The area of these plaster holes is littered with many small and large solution funnels. Under this funnel landscape there is a 100 m thick gypsum store , which geologically belongs to the Raibler layers .
The entrance to the cave is 1465 m above sea level, it is in the area of the municipality of Raggal in the Great Walser Valley . The name of the Trübbach cave is derived from the stream emerging from the cave, whose gypsum-containing water appears clouded by solution residues after heavy rainfall. With medium water flow, 1 m³ of water contains around 1.6 kg of dissolved gypsum .
The Trübbach cave was first entered around 1958/59, it has been a geological natural monument since 1984. The cave shows all Formenschatz a Laugungshöhle with flow facets , Laugfacetten (Stillwater facets), Laugtaschen, fillets, Laugungsdecken, Gipssausblühungen and standing like a backdrop from the ceiling leaching residues of other rocks (limestones, cherts ). The bottom of the main course is covered for large parts of fine sediment (sand, loamy sand, clay, gypsum sludge). Only the entrance area and the innermost spacious cave parts are marked by eruptions.
The total length of the gypsum cave known today is 423 m, the course of the passage is mostly horizontal. At the entrance the cave forks into two branches: the short and low south corridor is accessible, the entrance area of the 363 m long main corridor has been collapsed and inaccessible for years.
The location of the cave entrance is entered in the official topographic maps of Austria (ÖK 50-BMN sheet 142 Schruns, ÖK 25V-BMN sheet 142 Schruns; ÖK 50-UTM sheet 1224 Hohenems, ÖK 25V-UTM sheet 1224-E Bezau). The cave portal is located directly on the access path to Alpe Laguz.
Other larger gypsum caves in Central Europe are located in Switzerland: The Grotte de la Crête de Vaas in the canton of Vaud is the largest gypsum cave in Switzerland and the entire Alps with a length of 1,510 m. The 300 m long Lac Souterrain de Saint-Léonard in Valais (Switzerland) is also located in a large cave within a gypsum formation.
