The Association La Venta is a research group that organizes and runs various geographical exploration projects with particular attention to the underground world. Such projects are carried out using a multi-disciplinary approach, developing new ideas and using new research and dissemination strategies.
To achieve this goal, La Venta uses human resources and techniques acquired over twenty years of research carried out in extraordinary environments such as rain forests, depths of glaciers, remote mountains and endless underground labyrinths.

 

 
"In depth" by Dark Star

Dark StarI have just received a call from Giuseppe.
News are secondary to the fantastic sound of his thrilled voice. The beauty of exploration rather than the meters that are added to the knowledge are the human stories and the friendships that arise or are consolidated in those moments.
Giuseppe tells me that the internal camp, located at 800 meters of depth, in the complex lasted for well over 6 days. That must not have been easy at a temperature of almost zero degrees is my addition.
In these days of camp they explored, and a lot. The cave goes down to -900 with a development which now exceeds 13 km in total. The areas explored are mainly composed of meanders tall and narrow. And very wete from a significant water flow. It almost seems like Boy Bulok he screams to me excited from the Intermatica satellite phone.

 
From Italy to the depths of Uzbekistan

Il muroAfter "only" 38 hours of travel and a couple of days to obtain the permits finally the expedition Dark Star 2014 is operating.

The base camp has been set up below the entrance of Dark Star and the ascent that leads to the cave was equipped.
Sunday a group brought the diving material to the terminal siphon of the Siffonnaja cave (one of the many entrances near Dark Star, explored in the 90s).
Another group climbed on the plateau and yesterday has equipped the descent to R19, a cave explored and surveied in the 80s and of which the topography was lost.

 
Article on sulphates of the caves of Tepui on Sedimentology

Depositi di gessoThe article reports a study carried out by the University of Bologna and Modena in collaboration with the ETH Zurich, concerning deposits of sulfates, such as gypsum and alunite, and rare phosphates-sulfates sanjuanite and rossiantonite in the caves of the Venezuelan tepui.

The isotopic study of sulfur has identified a likely source of atmospheric sulfate ion, probably resulting from Dimetilsulfide (DMS), a gas produced in large quantities by biological activity on the surface of the ocean, or by processes of reduction in the Amazon rainforest.
