Sat 20 Jul 1996
Really did it this time. Pulled a big rock out of Sam's dig - just lots of loose bits to dig out of strongly drafting rift. Looked around the environs - various choked shafts & sections of small phreas on the Vd Schwarzmooskogel side of the surface chasm on the was to 161d. T/U 15mins
