A 2-metre shaft places us in a narrow joint that ends in a crawl. Once past it, it continues until reaching a shaft that is less than 10 metres deep. From its base, the gallery ascends in a south-westerly direction until almost reaching the level of the entrance mouth. Back at the base of the shaft, the gallery descends between ramps and drops, the longest of 6 metres, reaching its maximum depth at -32 metres.
