How interesting; I did Giants in the pre-blasting days, but I have no recollection of the 'Near Curtain'. What I do remember, though, is the low wet crawl through 'Backwash Pool' (was it called?), holding a 'stinky' at arm's length to pass it to somebody in the hope that it would stay alight.The horrible thing about the "old" pre-blasting & connection Giant's was the Near Curtain - it was about 30m. or so down the streamway from the entrance and a flat out crawl/duck in the stream.
