"To me this is like discovering that K2 is larger than Everest," Tim Allen, an expedition co-leader who studied the Chinese cave, told National Geographic. He was referring to K2, the Himalayan peak that is taller than all other mountains on Earth except Everest.
The measurements were announced at the Hidden Earth 2014 national caving conference, held in England from September 26-28.
More photos of China's supercaves are available on National Geographic Magazine.
