UIS Commission on Karst Hydrogeology and Speleogenesis

We would like to remind you the most important pseudokarst event in near future and before the 16th International Congress of Speleology. So, all speleologists and cavers interested in recent advances in non-karst caves’ exploration and research as well as who want to contribute to the preparation of the pseudokarst part of the Congress should attend this Symposium.

12th International Symposium on Pseudokarst
