The “Toratau” geopark is supposed to be created in the Gafuriysky, Ishimbaysky and Sterlitamaksky municipal districts of the Republic of Bashkortostan territorially covers boundary parts of the karst country of the East European Plain and the Ural karst country where the fl at sulphatic and mountain carbonate karst are respectively developed. On the territory of the geopark, all the main types of karst are developed, depending on the nature of the relief and conditions of their occurrence, the nature and degree of covering of karst rocks by not karstifying; almost all known forms of karst manifestation are represented. Here the largest cave of the Ural region in limestones — a cave Kinderlinskaya named after 30-th anniversary of the Victory. and the second longest cave system of Bashkortostan in gypsum — Isheevskaya, are located; and also high-output karst springs of South Ural — Berkhamout and Asken-Kul. In the territory of the geopark there are karst bridges and the disappearing rivers which were also rare in South Ural. The streams and the rivers vanishing in the ponors of karst funnels appear in their courses in the form of high-output springs in 2–3 km below the places of their absorption. It has been established that the main feature of the development of lowland sulfate karst is the predominance of its surface manifestations over underground ones, while mountain carbonate karst is characterized by a wider distribution of karst caves and high debit springs. The character of distribution of karst occurrences is determined by a composition and condition of karst rocks, their degree of exposure and the nature of covering of karst rocks by non-karst rocks, predetermined by the course of relief formation in recent times. The karst does not make essential negative impact on social and economic objects of the geopark, whereas fractured-karst waters are important for water supply of the population, and the high karst and speleological capacity of the geopark with existence of unique caves and other karst objects predetermines prospects for the organization on their base of touristic sites for mass, scientifi c and sports visits. Further researches of a karst and caves have to be directed to specifi cation of spatial regularities of their development, determination of modern activity of development of a karst, complex study of karst caves and, fi rst of all, determination of age of stages of their development for the purpose of reconstruction of history of formation of manifestation of underground karst forms in the modern and latest time.
