What are we going to do? In theory, the relief, photos and exploration of the Cueva de Los Bordos, a huge cave already explored by the French in the eighties, of which there is little information in addition to the hospital admission for histoplasmosis of the participants at the time.
We are eight, reduced to six after three days.
We're not fine and Montezuma is taking its rightful pledge.
But the cave is a giant!
A resurgence that pulls out a little less than one cubic meter of water per second is now dry.
The entrance attacks you with a nauseating smell of guano that inevitably you tread on and breathe throughout the stretch (about 2 km relieved).
Inside is very hot and you can breathe a little but the cave is really nice! It begins with a large lake and continues with an underground gorge trend: meanders up to 40 meters high, fossil galleries intersected by active ones, flows like giant jellyfish and a stretch straight north that concludes our journey. Clearly the cave is far from exhausting its surprises!
Is it not easy to cross it: after a few hours we feel the presence of carbon dioxide with headaches and difficult breathing.
The current of the river is very strong at times and you do not see where you're going.
Furthermore, you inevitably slips on heaps of excrements of the ubiquitous bats!
A myriad of crabs and fish keep us company too.
But we didn't just acted as cave animals, on the contrary!
The surrounding area is lovely and we explored it finding, at an hour's walk distance, a huge cave with a vault of 50 meters that closes on soil and stones. Avoiding scarcely many thousands of wasps that nearly assail Vitto and Salvatore on a ledge.
In short, we had fun!
The days have flown in and out between explorations and unforgettable swimming in natural pools of great beauty!
The caracoles (shells) collected and cooked by Salvatore have been a fitting end to a great week in the end of the world!
Obviously we couldn't miss the return to "civilization", again overloaded and without the carriers to help us. The rain caused them to desist but made us refreshed on the climb.

Meanwhile, on the left bank of the Rio we weren't surely still. Three new caves have been explored and relieved. Two Sime (pits) of more than 60 meters closed at the base by mountains of guano also with serious difficulties, breathing carbon dioxide, and a beautiful sub-horizontal cave in the colonies of Francisco Villa and Absalon Castellano in the municipality of Juquipilas
Now the expedition comes to an end. One more day to tidy up the warehouse and then a trip to the seaside for a day of relax. Now we really need it!
