The 25-km-long cavern system in basalt stonesrunning along the Serepok river to Dray Sap waterfall in Krong Nodistrict came to the general public for the first time as the result of aseven-year study conducted by Vietnamese and Japanese researchers.
According to the General Department of Geology and Minerals ofVietnam, its scientists and partners from the Japan Caving Associationfound an entrance to one of the caves in 2007.
Nguyen Van Thuan, head of the General Department for Geography andMinerals of Vietnam, said through many short field trips to learn aboutthe volcano Chu B’Luck in Buon Choah commune, Krong No district, theresearchers have found dozens of unique basalt-stone caves formed byeruption of volcanoes which are believed to be active millions yearsago.
Inside the caves, the scientists have found evidence of reptile species as well as human existence.
The longest cave, called C7, is around 1,100m with the width insidemeasured up to thousands metres and structures unique to volcano cavesformed by reverse lava eruption.
According to scientists, C7 could be the longest volcanic grotto in Southeast Asia.
Many entrances of caves are hundreds metres in width, runningthousands metres into the ground and possess many structures withscientific values.
The scientists agreed that thecavern system has all features to become a national geographical park aswell as a candidate for the United Nations Educational, Scientific, andCultural Organisation to recognise as a global geographical park.
Dak Nong, one of the poorest provinces, has already long beenconsidered a potential province of tourism with many waterfalls andbeautiful scenery.
With the newly-discoveredvolcanic cavern system, it’s time for the province, whose economy islargely reliant on forestry and agriculture, to take tourism economyinto its account.
Dak Nong’s representative saidthat the discovery of the system and the feasibility studies to turn itinto a national geographical park has great significance to thesocial-economic development of Dak Nong and the Southern CentralHighlands.
The cave system will help the province promote tourism further, he said.-VNA
