Cueva 3 Ref.a-1/c

The entrance opens at the bottom of a doline two metres wide by one point five metres long. From there a gallery begins, narrow at first but gradually widening, with a length of five metres. From its final part another gallery of somewhat larger dimensions begins, which ends after a distance of ten metres in a small chamber two point five metres wide. At the final part of the chamber a small dead-end hole can be seen.

On the floor of the first gallery there is a large quantity of blocks and sand, which are replaced at the end by a thick mantle of concretions. In the second gallery the lithogenic formations are clearly visible. The floor of the small chamber is covered by a flowstone mantle.

In the middle of the flowstone mantle covering the floor of the small chamber there is a small residual lake fed by incessant dripping from the ceiling.
