1998-1999: reconnaissances 4CDuring two investigations carried out in November 1998 and May 1999 two large caves located downhill, both near the dell and on the high surrounding mountains have been partially explored.
During these investigations we explored around 5km of underground tunnels, although most of these have not been fully explored. In some canyons we saw tens of caves with halls opening on vertical walls, thus we could only reach them through climbing techniques: free and aid climbing, fixed rope ascents. Torna al progetto

2001 - 2002 - 2003: expeditions 4CIn order to explore these caves and to discover new ones it will be necessary to equip advanced base camps in canyons and mountains, overcoming difficulties due to water transfer (there isn’t any known spring). As regards extremely deep and complex caves it will be necessary to equip base camps inside the caves.
4CDuring cave explorations we will carry out instrumental mapping, observations and geological sampling, surveys on physical data such as temperature, air flows, relative humidity, etc. As regards the spring lakes, research will be based on the underwater topography of the most significant pools and on the exploration of conduits that will be discovered. The goal is to produce the minimum impact on submerged ecosystems. Moreover we will try to describe through topographic mapping the morphology of inflow and outflow conduits in relation to the lithology of the explored sites.
 Specific hydro-geological studies will be carried out on water bodies: precise height measurements of each lake on the mean sea level and comparison of relative heights; measurements and comparison of temperatures; various types of chemical and physical analyses; measurements and monitoring of flow rates and levels, calculations of the speed of flow of intake conduits and drainage galleries. In the end a subaqueous photographic documentation will be realised, as it does not yet exist.
Some figures of the project that give an idea of the work performed: more than 70 researchers involved, 65 new caves explored, 8 km of underground topography, almost 200 geo-topographic observation points, tens of underwater immersions, thousands of metres of rope used within pools in mines and caves, thousands of kilometres walked, amongst all participants, on giant mountains without paths. Not to mention the numerous canyons descended for the first time by man. Torna al progetto

Between February and March '96 a new expedition was carried on to complete the explorative work of the dephts of the Aonda platform (so called by the name of the main chasm, 360 meters deep and almost 600 long) and to further deepen the study of the speleogenetic mechanism in the quartzites. The expedition, however, was mainly aimed at the production of a 16mm documentary dedicated to these extraordinary environments and in particular to their caves and to the research carried out by La Venta Association. To the expedition, completed with the support of RAI (Italian public television), took part also the director Enrico Hendel and a team specialized in nature documentaries.
In parallel with the complex documentation task, which forced the team to transport heavy materials to the bottom of the Sima Aonda, were continued also some speleological explorations, reaching the bottom of the Fummifera Acque Pit, 350 meters deep, and the exploration of the Bloque Sima, then connected to the underground collector of the Sima Aonda.

Expedition Juquila 2002”, Mexico JuquilaThe 2002 Juquila exploration put a real strain on men and equipment during the 10-day exploration of the Juquila Canyon.
The group was immediately divided into two teams for efficiency and security reasons: the first team started on the top of the canyon and had the task of exploring it while descending; the second team, thirty five kilometres down, had to equip a base camp and explore caves and springs on that side of the canyon before finally joining the others. They succeeded in the task but not without problems.
Apart from thorns and hot temperatures, constantly present in our expeditions, underestimating travelling times caused major difficulties. The area has turned out to be harder than we expected.
JuquilaThe canyon morphology, with its numerous landslides and drops, plus some small incidents (congestion, knee strain, broken superciliary arch with stitches, various bruises) considerably slowed down the descent of the first team. Nonetheless, the six members of the team speeded up, using the remaining stocks and managed to meet the rest of the group five days after the start, right on schedule.
The second team, approaching the canyon from the bottom, had many difficulties too. Despite using horses to transport equipment, carrying bags on our shoulders under the boiling sun, through thorns, rocks and a total lack of water, in nine hours we managed to reach a pass near the canyon. From there, with two more hours of extremely difficult descent (700 m drop in 800 m of development) the group finally reached the location where they set up the base camp. From here they carried out exploration and logistic activities.
This first exploration has allowed the development of a long-term research project in the area. Torna al progetto

The expedition, held in February 2009, had the goal to expand the cognitive framework of the karstic phenomenon in the quartz limestone of Venezuela, in particular regarding the hydrogeological, speleogenic and biospeleological point of view.
Specific target were the eastern offshoots of the vast Chiamanta Tepui, a range covering an area of nearly 1200 km2, topographically divided in several minor peaks, including Akopàn and Churì. Here, during a pre-expedition held in January 2008, we spotted several important cave entrances, some characterized by impressive resurgences on the walls.
The main problem we had to deal with was arriving to the cavities, which open on the high walls of the Akopàn Tepui, tackling challenging descents of almost 200 meters. It was essential using the helicopter to reach the top of the mountain, transporting one small autonomous team at a time.
During the expedition we collected an impressive photo and video documentation. For the first time in a speleological expedition we used the Inmarsat satellite system by Intermatica. This equipment allowed us to update, daily and in real time, a news page. Among the main explorative results, we explored the Akopàn-Dal Cin-Maripak system, with a 3,5 km development on huge active galleries.
During the expedition, the Venezuelan helicopter pilot Raul Arias spotted a large entrance in the highest plateaus of the Auyan Tepui. The cave was called Cueva Guacamaya and was explored a few weeks later by Arias, two Italian speleologists and a Venezuelan speleologist, Freddy Vergara.
