Scientists and cavers who are members of Britain’s Royal Geographic Society have led 20 expeditions into the depths of Mulu Caves near Miri, Sarawak, since the 1970s and explored over 500km of trails.
In those years, they have discovered underground rivers and caverns, including the Sarawak Chamber, one of the largest in the world by area, as well as a Garden of Eden and photographed Abraham Lincoln’s distinctive profile on the 154m-high entrance to the Deer Cave.
