The Oliero cave system has two main entrances de Cogol di Siori and Veci
east and west respectively.


















The Veci side cave has a small map up to 800mt, but apparently the caves
goes for over 2.4 km into a dry sump which is estimated to be about 500mt,
then the cave goes underwater for another km before surfacing in a second
dry sump. Max depth 59 mt.

Basically surveying of this areas will require "camping" inside the 1st sump
and water conditions/ weather forecast must be perfect for the camping days.
However we had rain forecast for the night Saturday, so after surveying most
of the deep part of Siori side, and with the strong flow present before the rain
we decide to avoid long rb dives.

The team decide to start surveying the Veci side in OC.

The Veci side is seldom dive, as surface access is even more demanding
than Siori.














Diving the Veci requires towing the gear in boats 250mt thru the river and
then walk it all over a slippery shallow spot, that when flowing is difficult to
even stay standing, let alone pulling gear. Then you must scooter tow it again
for another 100MTS to the cave entrance.












We laid 500mt of survey line and survey 180mt in total.

The Veci cave entrance is larger than Siori side, the tunnel also is higher and
wider, most of the time you can't see the opposite wall even with 10MTS viz
we had. The flow is less perceptible than thru the Siori "venturi".

The cavern drops quick to 30mt, then a slope of gravel reaches  50mt at the
cave floor, tunnel average 45mt and max 59 and as shallow as 40mt the first
500mt of tunnel. Water 9°C
