Описание
Морфология
After the first surveys in April 2022, the cave was eight meters deep and at least 20 to 25 meters long. In August 2022, an exposed fissure and an additional small chamber were discovered. According to the latest surveys, the part of the cave known so far currently has a length of almost 34 meters, is 8.5 meters deep and extends from north to south, for the most part beneath the Klusensteiner Weg. In both cave chambers there are rocks of the tropical limestone hummock relief of the Deilinghofen plateau.
Спелеотемы
So far, cave researchers have been able to find many remains of fossilized corals, mussels and turret snails on the walls, prepared out by water. During the first exploration, remains of stromatoporoids were also found. In the cave, besides corroded limestone blocks, there are also numerous stones from the Honsel beds and red-glowing red ironstones.
Гидрология
Since the cave is still regularly flowed through by water, it can be described as an active cave, as the cave formation is not yet complete. At the time of the discovery of the mist plume, the stream was completely dry.
Прохождение
Because of a distinct draft of air, the researchers suspect further continuations of the cave.
История
At the beginning of 2022, the cave was discovered in the Brockhauser Feld. Already in 2019, the Mendener Andreas Kolarik, who explores caves in his free time, suspected based on his discovery of the stream sink (Westphalian Schwalgloch) in the water ditch at the Klusensteiner Weg that there could be a cave at this spot. Through warm cave air rising at the ponor, discovered in the winter that followed, the suspicion of a cave located there was strengthened. After the city of Hemer had supported the exploration of the cave and had a constructional entrance prepared, the first surveys took place in April 2022. Further work followed in August 2022. In November 2023, a partial collapse occurred directly next to the entrance point north and west of the Klusensteiner Weg road. A hole about 1.5 by 1.5 meters in size opened up, which quickly widened toward the roadway. A full closure of the Klusensteiner Weg and covering of the collapse point with a grate followed.
