From Sinkholes to Waterfalls
|
Some of the world's largest sinkholes, also called dolines, plunge into the karst terrain of New Britain. In Ora Cave, the team followed the river as it tumbled through passages the size of subway tunnels. They also discovered two other major caves, Phantom Pot and Mageni, where cavers surveyed four miles (six kilometers) of tunnels, climbed four waterfalls, and found luminous limestone curtains. Near the expedition's end, the team spotted a previously unknown doline about 12 miles (19 kilometers) west of Ora.
