At the end on N37 or #Mullamullang This is the text on the slide, Dick!! From Dick.. My recollection (I’m sure you’ll correct me if you think I’m mistaken) is that I found and first entered it; I’ve a memory of plonking my hand and forearm into this thick layer of almost talcum-powder fine dust and thinking of moon-dust and thousands upon thousands of years of slow accumulation. The picture in my mind is of quite small, sort of elliptical cross-section tubes, barely high enough to crawl along in places, and finding fairly quickly numerous branchings, and considering its maze-like aspect I suggested the name ‘ezam’. And I seem to recall its really poor acoustics as we called out bearings etc...
