Abstract

Description

Photographer's note: The Muller Range contains magnificent cave formations sculptured from dissolved limestone. The large numbers of caves, the frequent occurrence of dry valleys and rivers disappearing underground and resurging at the foot of the plateau provide evidence of an extensive underground drainage system. In 1979 an Australian caving expedition explored a cave system which began in the Atea doline above the source of the Nali River on the edge of the plateau and followed it for 30.5 kilometres, which at the time was the longest cave found in the Southern Hemisphere. A subsequent expedition in 1982 explored the nearby Mamo cave to a depth of 576 metres and a length of 53 kilometres. This photograph was taken on the Muller Range on the path between Hareke (Koroba – Lake Kopiago road via Tumbudu Valley) and Atea Kanada (and Nali source in doline at the Muller escarpment base).
