The Bärentalhöhle is a typical cave in the Swabian Alb in the Bärental near Hütten ( Schelklingen ).
A horizontal, usually very narrow corridor makes the drive tiring. Almost the entire cave was only uncovered through excavation activities by speleologists .
The Bärentalhöhle is a bat quarter. From October 1st to March 31st, driving is generally prohibited according to Section 39 (6) of the Federal Nature Conservation Act.
Research history
Gustav Riek , who held the Chair of Prehistory in Tübingen until 1965, organized archaeological - paleontological excavations in the Bärental Cave as early as the early 20th century . At that time he found several bones from the cave bear . During his excavations, he lowered the first 28 meters of the cave to today's level.
Since then, the Bärentalhöhle has been an excavation object.
In 1986 a group of the ARGE Höhle und Karst Grabenstetten started digging at the end of the cave (28 m). After an excavation of 7 meters, the subsequent, air-filled 300 meters cave could be entered and documented.
In 2002, after a long break, the youth group of the State Association for Caves and Karst Research took place again, which were intensified in 2003 with an "excavation marathon" with 72 hours of shift work. Since the cave at the excavation site had no ventilation at all, the CO 2 accumulation had to be counteracted with artificial ventilation .
Over the next few years, digging continued with varying intensity, from 2008 onwards by members of the Blaubeuren cave association.
In 2009 a crevice opened in the cave ceiling, from which a clear draft emerged. This solved the CO 2 problem. After long and narrow corridors, two very spacious chambers opened in 2010 for the Bärentalhöhle. Shortly afterwards the “branch hall” was discovered with a height of 2 meters. A strong draft encouraged all diggers to be on the right track. The cave was now 388 meters long.
In order to continuously document the conditions in the cave, a wireless telemetry system was installed in 2010 , which transmits temperature, air pressure and CO 2 content to the Internet.
In 2011 the “oasis” was discovered, where the otherwise very dry cave suddenly becomes very damp. In the back the cave branches out; several sequels make it difficult to decide where to continue digging.
An additional difficulty arises from the fact that there is hardly any space to deposit excavation material and therefore hundreds of sandbags with excavation material have to be transported out of the cave every year in complex "bag actions".
Overall, the Bärentalhöhle is a typical, small-scale Alb cave. However, as can be proven by drilling, the corridors are much more spacious, only they were filled with sediment in the last Ice Age . What is striking is the pressure pipe profile that runs through the entire cave.
