The Elsachbröller is an active water cave on the Swabian Alb , the two entrances between Bad Urach and Grabenstetten are only 200 m away from the famous Falkensteiner cave . The partially very close and strong loamy cave has many traps and should therefore only by highly experienced and well-equipped cavers traveled to.
origin of the name
The term " Bröller " in the southern German-speaking area refers to a spring cave from whose portal at certain times of the year (e.g. after prolonged rainfall or when the snow melts) large masses of water "roar" or roar. " Elsach " is the name of the stream, the water of which originates largely in the Falkensteiner Cave and to a lesser extent in the Elsachbröller. It is a tributary of the Erms .
Research history
A hunger well on the opposite side of the valley from the Falkensteiner Cave was known long before the Elsachbröller was discovered . At the beginning of the 1960s, after clearing the debris, cave explorers discovered access to an initially very narrow cave system, which, however, expanded towards the mountain to form water-bearing cave passages that are very reminiscent of the Falkensteiner Cave. After emptying two siphons in 1975, cave explorers discovered a passage that led to a point just a few meters to the right of the existing screed entrance and the end of which was filled with debris and clay. A few years later, an excavation created a second entrance to the Elsachbröllers system at this point. In the 1980s, the cave was driven up to a length of about 2500 meters, of which, however, only 800 meters were measured precisely because of the enormous difficulties in driving it.
Grabenstetter large cave
The proximity of the Elsachbröller to the Falkensteiner Cave as well as the course and shape of some of its passages suggest that both caves once formed a coherent system, which was separated into two sections by the deepening valley. The corridors that today belong to the Elsachbröller formed the continuation of the higher cave sections that belong to today's Falkensteiner Cave. While the Falkensteiner Cave is still traversed by a flowing body of water, the main water supply to the Elsachbröller was cut off by the formation of the valley. The left part of the Elsachbröller itself still has a cave stream that flows through the sinking into the "Ur-Falkensteiner Gang". The Elsachbröller is heavily neglected due to the low flow of water; its cave stream dries up at normal water level in the area of the Urfalkensteiner Gangs and today drains like the Falkensteiner cave into the Elsachtal. The Urfalkensteiner Gang itself is one of the most powerful cave sections in the Swabian Alb. The hypothetical possibility of a large Grabenstetter cave led to an unresolved question about the further course of the cave. The end of the passable passage in the right part of the cave forms a massive silting; an excavation through the Pattexschluf was stopped unsuccessfully. Another attempt to advance via the Büchelbrunnerbröller into the presumed continuation failed due to the extremely difficult conditions. In connection with the total karstification of the Alb, the question arises as to where a large Grabenstetter cave of this dimension could have drained to. Drainage into the Uracher Mulde via a large number of smaller springs would be conceivable. Daring and controversial is the theory that this continuation could be related to the blue cave system . The exact relationships have not yet been finally clarified here.
