Over 300 dry (fossil) and active (stream) caves of thermal and hypogene origin are known in the upper Cerna Valley, between Naiba Valley and Pecinișca Village. The large variety of caves is sustained by a complex geology developed along the graben, with granites outcropping along the Cerna River’s thalweg. The presence of this granitoid pluton is the source of a large geothermal anomaly in Baile Herculane area and a smaller one 21 km north, where two thermal springs are located. A synthesis of the Focul Viu Caving Club explorations, emphasizing the Great Cave of Șalitrari (the longest cave in the area) and Ogașul Adânc, a stream cave that traverses the limestone strip, is presented in this chapter. |
