Das Karstgebiet um den Bol'shoj Tkha'c

In preparation of declaration of nature reserve, an extensive biological and geological examination of the limestone massif of Bol'shoj Tkha'c (Kaukasus, Russia) was carried out by the association Umwelt und Bildung e. V. (Gosen, Germany) in summer 1997. The limestone massif is an alpine to tempered karst landscape with typical karst phenomena. Most of these phenomena are ancient and the explored caves are usually not active.
