These incredible images
show British scientists on an expedition to map a 'never-ending' cave
network in a project that dates back more than 30 years.
The twisting network of
caverns underneath Gunung Mulu National Park, in Sarawak, Borneo, contains
the largest cave chamber in the world, the largest cave by volume and what
is believed to be the largest cave passage.
Scientists carry out
bi-annual visits into several caves and have so far mapped out an
incredible 186 miles of the underground network.

calcium-formed funnel which transports rain water from the surface into
caves underneath Gunung Mulu National Park, in Sarawak,
Using lasers and other
equipment they measured the dimensions of different sections of the
numerous caverns stretching throughout the UNESCO World Heritage site and
feed them into a computer to build up the map.
Working with Borneo's
National Parks authority, the team of Brits also began mapping the area
above the caves to help tourists trekking between the cave mouths know
where they are.
