"What are you doing down there?"

Phil Playford watches as Dave descends into a small Nullarbor blowhole. Blowholes were a novelty to start with. Later I estimated that there were 10,000 -100,000 in W.A. As far as I know no one believes the number, but no one has produced a better number. This would be on our tour around checking the whole Eucla Basin before the field season trip of just Dave and me. From Dave's Narration notes.. In 1965 I suggested that WAGS would eventually want a Bulletin on the Eucla Basin in WA and that since the only sections to measure were coastal cliffs and cave walls, if Joe Lord wanted a good bulletin the author would have to be keen on cave exploration. Since I was keen to do it, Joe Lord agreed to take the opportunity while I was around. I found Bill Crowle for a field hand. He was an experienced cave explorer from NSW and was keen to explore Nullarbor caves and get away for a bit from his career as draftsman. So around June 1965 we started work with a reconnaissance accompanied by supervisor Phil Playford. All the DL TIF files from the CD of Dave's Nullarbor Caves & Geol 1962-68 filed in the CD drawer. Several were edited and loaded years ago.. We shared film during the GSWA mapping expedition during 1965. PEP DL blowhole June 65
