With a Submarine drone Through, a group of speleologists has achieved a historical milestone when locating the deeper flood cave of Spainthat sinks 140.5 meters and that has been located in the siphon of the birth of the Castril River, in the province of Granada, according to the Andalusian Federation of Speleology and Descent of Canyons (FAE).
The team that led the expedition ensures that the discovery “It is an important advance” In the knowledge of the karst system of the Sierra de Castril, a mountain range with peaks exceed two thousand meters and is located north of this Andalusian province.
It has not been an easy company, experts recognize. The main difficulty was to deal with the overflow of Siphon of the Castril Riverwhich has always raised a lot of interest among the caleologists for their depth and by the force with which the water emerges from there.
Using an underwater drone, the team led by Antonio J. Moreno managed to overcome the previous brand of 103 meters from the blue well in Burgossouth of the Cantabrian mountain range. On this occasion, the device managed to descend to a much larger depth: up to 140.5 meters, the largest brand that is recorded in our country to date.
It is no accident that a robot has participated in the finding, this group of experts maintains. In fact, they emphasize that the collaboration of this drone has been fundamental and believe that the use of this technology will be key to the exploration of underground cavities flooded in the future.
Far from other European underwater caves
Despite the extraordinary brand, the flooded cave located in the siphon of the birth of the Castril de Granada River is still far from other European underground cavities such as the Hranice abisma chasm located in the Czech Republic and that houses one of the deepest underwater caves in the world, with more than 400 meters, although it is estimated that it could be much greater.
Another large flood cave is located in Italy. We talk about Pozzo del Merrolocated northeast of Rome and presents a depth of 392 meters, according to the results of an immersion made in 2002.
