The World About Us (1967 - 1987): Mysteries of the Green Mountain
(1978)
Weird and exotic jungles clothe the slopes of Mount Mulu, the newest [in 1978] national park in Sarawak, Borneo. They have been home to the largest expedition ever mounted by the Royal Geographical Society.
To unravel the mysteries of those jungles experts from many nations wedded the techniques of science to the skills of those who live in the forest - stunning lizards by blowpipe dart, tracking a civet, stalking termites, trapping moths, even weighing the leaves on the ground.
It was an exploration among amazing sounds and spectacular landscapes with soaring pinnacles and, beneath the jungles, rock honeycombed with gigantic bat-filled caves.
