Benarat 2005
The Mulu area of Sarawak is one of the most significant karst areas in the world so has long been popular with British cavers. This team proved that the Terikan caves formed a single 32km system: they also extended the Whiterock caves by 17km to a total of 20.9km and connected them to the Clearwater caves, making this the tenth longest system in the world, at 130km. There is obviously much more work to do in the area.
