During the expedition to Tajikistan, biologists from the University of Opole conducted a study of the salt mountain Khodja Mumin near the city of Kulyab. During the exploration, they discovered and examined a previously unknown cave.

Mount Khodja Mumin has an oval shape, its length reaches 8.5 km and rises above the plain to a height of 900 m (1,332 m above sea level). It is the second largest salt mountain in the world. The salt reserves amount to 30 billion tons.

During the exploration of salt caves and the search for cave organisms, the scientists discovered and examined a previously unknown cave, which they called the “Kłysia Cave” – ​​after Dr Grzegorz Kłys from the Institute of Biology, the expedition participant. The cave is over 450 meters long and it has over 70 meters of elevation. They have collected many species of cave beetles and flies, possibly new to science (material is being prepared).
