An international team of divers have returned from an expedition to the Pozo Azul cave system in Spain. The group, with cave divers from UK, Spain and The Netherlands were able to pass last years endpoint.During a 15 day campaign they were able to extend the cave for another 500 meter to a total of 9685m of which 9135m has to be done diving, a world record.
The furthest point was reached by Jason Mallison along with John Volanthen, Rick Stanford and René Houben during a three day push dive.
The group was able to pass the third sump (about 260m from the limit set last year), and followed a streamway for about 180m, before reaching another sump, sump 4. This new passage is nasty terrain: razor sharp rocks, with 27 cascades for a total vertical distance of 10 - 15m to reach Sump 4, wich remains undived due to the fact that they were unable to move all their heavy equipment to here.
Pictures of the expedition can be found on the respective facebook page, along with a gallery of all participants.
