Franz auf der Maur
The Hölloch has an accumulated length of 203 km. In this report, we will examine if the cave systems to the east could be connected to the Hölloch. Even though the 38.7 km long Silberen system is extremely close, the connection of the two has as of today, proved impossible. To the east of the Silberen system, several caves continue (more than 30 km overall) that are connected hydrogeologically. The members of the Arbeitsgemeinschaft Höllochforschung AGH are slowly able to link single caves together.
