The limestone mountains of the Gunung Mulu National Park and the adjacent Gunung Buda National Park, in Sarawak on Borneo, contain over 400 km of cave passages mapped by a series of British and American expeditions. Many of these caves, both the active river passages and the abandoned high-levels, are very large and they include the world's largest cave passage and the world's largest cave chamber. Sediment dating has demonstrated that the caves’ major trunk passages evolved as a sequence over more than two million years in response to falling base levels as land surfaces were lowering adjacent to the limestone mountains.
