Thanks for the info WNT, very interesting & yes, the scenery outweighed the pain one hundred fold; perhaps not the Dension section tho, that was 2.5 days of mind games.
At one point on this section we had only travelled a bit over a kilometre in 5 hours...pretty demoralising on day 10 or so of a long exhausting walk when you expect / want to get home.
Back on the yabbies, I found the 3m tube (5-6mm dia.) the most useful on this trip, but also carried a 40cm tube in my pocket for 'on the go' drinking.
On previous trips (eg. Franklands) I had used the syphon method for robbing the precious yabby booty; ie. run the tube down hill of a hole & use gravity to draw out the good stuff.
On the POW's quite often this was impossible, so sucking up 3m worth into the actual tube then just blowing it into your water container was the best method.
Plenty of times all of us got a good mouthful of tarry looking liquid mud in lieu of clear life preserving H2O.
Funny how by the time we were on the Denison, wet cold & covered in water we were so quick to curse it again...but that's life in the Tassie wilderness
