IC A. Wilde * INTRODUCTIONo The limestone of the Chimbu is striking and undoubtedly gives the area its charm and characteristic beauty, with its steeply sloping escarpments 9 vertical cliff faces and deep gorges which have an abundance of caves and potholes. This paper describes caves North of Kundiawa - Chuave in the Porol Escarpment and Singga River areao (See location map.) Caves numbered 16, 17, 19 9 24 9 25 and 26 have been described from Parker (1965). The majority of the caves were explored by Van Watson 9 Bill Sanders? Tony Maddern and the author~ mainly during 1972 and early 1973. TOPOGHAPHY,, The Porol form an impressive series of cliff faces~from-'tFi'e south, ~nd from the north they are steep dip slopes varying from 40 in the west to near horizontal in the east near Chuave. As can be seen from the map 9 the backslope is drained by the rivers Singganigl and Kwinigl. Running north to south is the deep steeply inclined 'V' of the Chimbu Gorge at which point the Singganigl, Kwinigl and Chimbu meet. The Porol reaches an altitude of 2450 m near Chuave where it is covered by dense rain forest and virtually uninhabitedo On the northern side of the Singga. the limestone steeply rises and continues along the Upper Chimbu Valley towards Gemboglo The slopes of the Porol Escarpment are cultivated with the occasional hamlet on the crest of the westerly end. To the west, the Chimbu Limestone continues to Nogare (east of Kerowagi) and east beyond the limestone massif Elimbari (2SOO m)o GEQ~Oqio Known generally as Chimbu Limestone 9 the area has been geologically mapped by Rickwood (1955) and more recently Bain, Mackenzie and Ryburn (1970)., The karst morphology was referred to by CoSoI.Ro06 (1958) and has also been mentioned by Jennings a.n(l Bik ( 1962) 9 Champion ( 1968) and by Williams ( 1972). Karst occupies 87 sc~ km in tertiary limestone which could reach a max~mum of 1000 m (at Mt .. Elimbari) in thickness and dips 30-40 to the north or north-east. The long, sharp limestone ridges are orientated roughly north-west to south-east to 300 m high on the south-west sides; local relief reaches 1200 m (above ·.rahgi Valley) with the cliff faces being commonly broken and cavernous with abundant faultingo There is an east-west fault in the region of the Sikuri Pass ·where Bibima. is located, which undoubtedly gives the system its great deptho The ranges are of Eocene and Oligeocene limestone overlying the Upper Cretaceous Chim grou:D of shales to the south and above them are the Miocene sediments to the north. :~n;2na c~;..
