Hidden Valley 1993

During January 1993 a joint Sarawak/British team carried out a lightweight reconnaissance expedition into the Hidden Valley on the eastern side of Gunung Api. This was the first expedition to explore this area of the Park since the Royal Geographical Society expedition of 1977/8. The expedition aimed to cover as much ground as possible in the limited time available to gauge the potential for a future caving expedition to this area. Prediction Cave was re-located and six other previously undocumented entrances were recorded.
