This expedition is oriented towards exploring the caverns in the Lake of 31 miles. Because of the geological composition of the region, basically formed of limestone, we are led to believe that an important number of caverns and caves do exist in this lake. 

So far only a few caverns have been discovered at shallower depths. However, no diving exploration at deeper depths has been done to this point.

We are planning to dive on Trimix mixed gas.

Please be advised that this is lake diving conditions. At the surface, the water is 72  F (21C) but only 38 F (4 C) at 40 feet (12 meters). 
In July the water column is divided into two thermo clines (25 feet and 40 feet). 

Nottman provides security while we dive.
