the last frontier

British explorers map out ‘never-ending’ cave network underneath Borneo jungle. More pics here. The Mulu Caves Project has been mapping these caves under Borneo’s Gunung Mulu National Park since 1978. Explorers claim the mapping will continue for generations. And they say the Earth isn’t hollow! (When I think about these vast underground cave systems that go on forever, the fantasy lobe of my brain can only think of the Mines of Moria and Gandalf warning Frodo that “there are older and fouler things than orcs in the deep places of the world.”)
