Mary climbs up into the dome in N37

We think this must be the Easter trip...1967 with WASG Can't remember who the young chap is! Murray Thomas, No! see comment as a note on screen! Steven Janicke was on the 1967-68 trip. Will send this to WASG for a comment. Notes... Then the longest cave in Australia, discovered on SUSS Nullarbor expedition 1963-64. 3 miles to the end with 6 miles of passages mapped. see... www.caves.org.au/helictite/abstracts0.html To quote Glenn............................ Title: The Origin and Development of Mullamullang Cave N37, Nullarbor Plain, Western Australia Authors: Hunt, G.S. Published: 1970, Helictite 8(1):3-21 Abstract by author: Mullamullang Cave N37 is the longest and most complex cave on the Nullarbor Plain, Southern Australia. Unlike the other caves, it possesses extensive levels of phreatic solution tube passages which permit stronger inferences to be made on the development of the collapse passages constituting the bulk of Mullamullang Cave and other deep Nullarbor caves. These passages have been formed by collapse through overlying belts of solution tube networks along an elongated zone of cavitation in the limestone. Massive breakdown was probably initiated at depth within the zone, at least 50 feet below the present water-table level. Upward stopping of the collapse would have been facilitated by the higher network levels in the zone, such as the Ezam and Easter Extension. Channelling of groundwater flow under the Plain is suggested by the belt-like nature of the networks. An epiphreatic origin is proposed for the network levels though convincing morphological evidence is wanting. Eustatic changes in sea level have been of fundamental importance in the development of the multiple levels. Wetter periods in the past were probably important as little development is taking place under present-day dry conditions. Correlation of wetter periods with Pleistocene glacials would help explain the development of huge collapse passages, but such a correlation cannot be assumed on present evidence. Massive collapse and doline formation were followed by subaerial weathering and vadose activity which modified the cave - especially near the entrance. Correlation of levels in Mullamullang with those in other Nullarbor deep caves is attempted. However, Mullamullang Cave is unique probably due to the lithology of the Abrakurrie Limestone in which it is developed. Includes: 6 photos, 36 refs search for other N37 images on Flickr... I have records of all the films I bought from 29.7.64 in the Pentax notes book. I had some Tri-X around Easter '65 but the list stops at roll 38 on 20:9:67 for a 20exp. roll of Kodacolor-X $1.71 This shot is from a print, not sure if it is a print from a slide, getting too long ago. But I should be able to find the neg or slide. CHECK The list covers whether the film was a reloaded cassette in the case of B&W KB-17 etc Or the brand and roll length, 20 or 36 exp. with the price paid and date processed or printed! The list continues till the demise of the SV1a and mentions the SV in April 1965. To be continued...
