History

 
1976established as a National Natural Landmark.

Description

The Black Chasm is famous for extremely big calcite crystalls called  dogtooth spars. It also has  helictites. and other rare speleothems, which make the cave visit very impressive. This is the youngest of several show caves in area.

The tour descends about 20m on steep concrete stairs to the Main Hall. This huge chamber is full of speleothems like stalactites, stalagmites, draperies and columns. Other highlights are 25m deep shafts with clear lakes on the ground. But the highlight is the Landmark Room with its spectacular arrays of helictite crystals.

The cave ist at the moment in a process of further development. The administration plans to open a second tour, the Rapunzel Tour. It will lead down to the cave lakes which are 25m deeper on a staircase from the Colossal Room. The tour is named after Rapunzel's Hair, a group of impressive, twined rope-like roots from an oak tree far above at the surface. This will be the end of this tour. However, the works have not yet started and as far as we know there is no schedule so far.
