In order to coordinate and manage the excavation activities in the Hessenhaudoline and lateron the Seligengrundhöhle the cave explorers of southern Germany formed to become the Arbeitsgemeinschaft Blaukarst in 2005. At the moment there are about 60 members. The following cave exploration associations are involved:
All of these four cave clubs support the Arge Blaukarst (working group Blaukarst).
The excavation activities at the Hessenhauhöhle and the Seligengrundhöhle are only possible due to the many voluntary cave explorers, spending their free time. All necessary expenses are financed 100% by donations.
More information as well as the current status of research can be directly found on the Arge Blaukarst’s website.
