Photo by @salvarezphoto | The Ora River forms a massive waterfall as it pours from a cave entrance more than 50 meters up the side of the Nakanai Plateau In Papua New Guinea's remote island of New Britain. This image is from a National Geographic sponsored expedition to explore the huge caves on the island of New Britain. 21st century exploration often means climbing up and into places like this.
