Avenc Joan Cabeza

The pit begins with a wide 49-metre vertical drop that at its base presents a ramp heading SW which ends in a drop of just over 3 m. Here there is access to a lower chamber located below the base of the main shaft, through an unobstructed passage that gives access to a 2.5 m drop reaching the lower little chamber, 9 m long by 4 m wide, with an irregular ceiling from 1.20 to 2 m high. The part located furthest N is connected with a -3.30 m shaft cleared on the ramp of the main shaft. On the left we find a small descending crawl through which we can progress about 2 m more and reach the maximum depth of the cave at -67 metres.

If from the bottom of the entrance shaft we head about 5 m in an E direction we will find a small depression that leads us to a descending crawl beneath a flowstone. This crawl, about 0.80×0.40 m, opens out into a small 5.80 m shaft that is easy to free-climb down. The small shaft, of irregular dimensions, has walls covered with flowstone and other formations, and opens 2.90 m above the floor to form a beautiful little chamber of 2×2 m. A ramp on the left leads us to a -0.70 m drop, where a tiny crawl prevents further progress in this sector, reaching 62 m of depth.

At the -25 level of the entrance shaft and on its N. wall, there is a window, difficult to access, which gives way to a chimney that after 10 metres of ascent emerges into a chamber beautifully decorated by lithogenesis. This is the Sala Flash Black Corb, about 8 metres high and whose ceiling lies very close to the surface. In a corner of the chamber there is a drop that leads to a niche that once again connects with the main shaft.

The small shaft has walls covered with flowstone and other formations. The Sala Flash Black Corb is a chamber beautifully decorated by lithogenesis, of great beauty due to the lithogenic coating it presents.
