Description

Morphology

An artificial funnel leads us to a small narrow step, where an inclined conduit places us in a small room with an elongated floor plan blocked by debris. In the step mentioned above, we find a crawlway of about 3 metres that leads to the upper part of a step where a narrow passage places us in a small round room with a low ceiling and no continuation. Descending the step we reach the base of the elongated floor plan that ends shortly at its extremes. The continuation is through a very narrow vertical conduit that ends at -8 metres in a small elongated room.
