Small pit 15 m deep. Through a very narrow mouth and after overcoming a small step of little more than 1 metres in depth, one reaches two possible continuations.

Following the direction of the entrance joint, some blocks embedded in the centre of the gallery must be overcome. From here the gallery narrows until after overcoming a crawl that widens again to, within a few metres, remain closed.

Just below the entrance mouth a gallery begins on a steep slope that quickly gains depth and among a good number of blocks one reaches the point of maximum depth. Here there is a muddy crawl that gives way to a small chamber with an inclined ceiling in which one can climb up a ramp and reach two small chambers.

In the two small chambers an important lithogenic process can be observed.
