Fifty-seven new caves were discovered in Phong Nha – Ke Bang National Park in Quang Binh Province, located in north-central Vietnam, on a recent expedition of British cave experts.
Situated in a 2,000 square kilometer limestone zone, the Phong Nha – Ke Bang National Park UNESCO World Heritage Site houses one of the world’s two largest karst regions and the largest cave system known to date – Son Doong.
The People’s Committee of Quang Binh was informed of the results of a recently concluded expedition into the park by a group of cave experts from the British Cave Research Association on Wednesday.
Howard Limbert, who led the expert team, said his group discovered 57 new caves during their trip.
According to the team’s report, many of the 57 caves were carefully measured and recorded for documentation purposes.
The caves discovered during the trip vary in length, with some stretching over 2.5 kilometers, though Limbert noted that the measured lengths were not exact or confirmed, and that the group had not thoroughly explored each one due to lack of time and unfavorable weather conditions.
A unique feature in one of the caves discovered on the trip was that it had been formed at the bottom of a massive lake, while most other grottos found at the park are products of the dissolution of limestone mountain ranges by rivers.
