Description
Morphology
The Numburghöhle is the largest cave in the Kyffhäuser area. After the dewatering in October 1988, huge halls and high domes were discovered that even exceeded the size of the Großer Dom of the Heimkehle.
Hydrology
Apart from a small part, the Numburghöhle is entirely under water. Through the massive lowering of the karst water level by the copper shale mining near Sangerhausen, the cave was dewatered in October 1988. The mining operation itself was hardly in a position to lift the accumulating masses of water; there were further problems with the high salt content of the water. Thus the lowering of the karst water level had to be stopped for cost reasons. The cave was flooded again in only a few weeks. In addition, water from the Kelbra reservoir seeped into the cave.
Progression
After the dewatering in October 1988, the entire cave was traversed. The cave entrance was closed after the flooding.
History
The Numburghöhle had been known as a small cave since 1928.
