Description
Morphologie
The cave is accessible via two adjacent entrances about 10 metres apart and has a surveyed length of 1469 metres with a height difference of approx. 40 metres. The passages are aligned along two intersecting joint directions on two levels. Both entrances can be closed with steel grilles.
Spéléothèmes
The cave stream flows through several sumps, a waterfall, beautiful sinter basins, plunge pools and several lakes.
Hydrologie
The Angerlloch is an active water cave. At the time of snowmelt and after heavier rainfall, the lower entrance is often under water.
Progression
In the first section, the passages essentially follow the cave stream up to a large sump, the Volksbad, which takes its name from the steep, slippery walls that must be climbed when bypassing it, something that often fails spectacularly. Behind this bypass, cave explorers used to be able to sign the cave book at the Kristallsiphon. In the deepest part of the cave, further progress requires siphoning and wading through the 25-metre-long Kristallsiphon, climbing a 5-metre-high clay wall and abseiling into a 7-metre pit above the Eisensee. A visit is recommended only for experienced cave explorers and with suitable equipment (mountain boots, climbing harness, rope, overalls, helmet, headlamp, sufficient battery supply).
Autres détails
Because of its proximity to the valley, the Angerlloch has long been known and well researched. The cave is very popular among cave explorers as a training ground and is also used for cave rescue exercises and for guided tours by youth groups. The cave has been designated a valuable geotope by the Bavarian State Office for the Environment (geotope number: 180H001).
Bio
In winter, the cave is protected because of the bats hibernating there and may not be entered between 1 October and 30 April of each year by order of the nature conservation authority.
