The cavity was cleared and explored in spring 2010 by archaeologists from Castelldefels down to the -19 metre depth, ending the cavity at this point as no apparent continuation was found. Members of SpeleoCorb, having a look around the entrances of the area, discover this new cavity of which there was no record, observing that it had already been explored on finding “spits” at the entrance. On 28 November 2010 they explore the cavity, re-rigging it and removing stones from the bottom for four hours, until a small hole opened through which they calculated that the stones fell about 30-40 metres deep. The following Sunday and after several hours of effort, they manage to widen the passage and descend to the new base, from where they have to remove all the material fallen from the preceding pit. The following weekend they manage to descend to a large rock that blocks the continuation, leaving only a reduced passage, through which when throwing stones they are heard at great depth. The following Sunday they manage to remove the rock, install a 40-metre rope but are left hanging in the middle of a pit 8 metres in diameter without seeing the bottom. They return with a 100-metre rope, managing to reach the bottom of the pit which measures 61 metres of vertical, naming it “pou Yu-Yui” for the impression it made on them the first day when left hanging in the middle of the pit.

Currently work is being done at the base of this pit, where a 2.50-metre-high wall has been built with the accumulated stones, and a protection net has been put in place to prevent their possible fall.
