PLP 06/11/2010
The water level is low today, 50cm shorter than usual. This facilitates the passage of the vaults before and after wetting zone traps. The water is clear enough and the current virtually nonexistent. When I go into the cave, I see that the two arms of the river is dry.
The first objective of this output is the escalation of the jump of 4 feet in the room Grigri to verify the potential of the fireplace that overlooks it.
On top of that it appears a bit obvious departure between the blocks. The place will be difficult to achieve.
By cons, 6 feet above me, another start seems much more interesting, so I would come back with a harness a little more appropriate than diving.
Room Grigri
Topographical traps have made the summers 23 and 24 October ( Fortifications ) at 2 points spent also found a sketch exploration of the cavity, the second objective the day is to continue in post-topography traps and make some photos.
While I prepare all the necessary equipment, I suddenly heard the sound of water abnormal. Dry arm of the river is being recharged quickly.
Strange, is probably the effect of showers this morning.
It soon becomes worryingly, 30 minutes, time to pack everything up and the level has risen 50cm.
I'm about to cross the vault wetting (almost Siphon) that separates me from the start of S2 or my dive bottle waiting for me when I clearly see that the level starts to drop. 10 minutes later he will have decreased 20cm ...
water rises again without exceeding the maximum score observed so far and that is what I knew from previous dives. Although
could not measure it, I also experienced a significant drop in water temperature and air.
This fluctuation has been observed nearby by Paul De Bie in Lake Cave in contrasts when browsing SC Avalon in 1994 (Insight 22/1995).
Finally, just add water to the mill of hydrogeologists.
The concern is subsided, but I still prefer to abandon the topo for this time to remain alert to suspicious behavior River.
I therefore turn to the objective plane -bis , besides a few pictures, a few ideas first change me.
Hall Mirror
A narrow passage at the top of the second room, called the Mirror Room , lead me in a small room which I will take Trendelenburg some altitude and whose scree at the top should perhaps be désob a session, no obvious result.
The ballad continues beyond the Mirror Chamber to join the river in another small room also discovered on October 16 where I see a continued beyond a squeeze it will shunt by dipping or negotiate seriously.
Back in the Mirror Room, I decided to tackle another constriction at the bottom thereof. (Visible here )
The portion passed, I find myself in a worrisome area crumbly. A little planning to crowbar the next time will continue to 4 feet on a dozen meters and can be more.
a squeeze to tame ...
's enough for today, friends waiting for me at the local level. The traps will be flying back with a totally zero visibility and a current well marked.
TPST: 5h
