Cova de Mariver de Martís

The SE entrance leads to a shaft of about 5 metres, slightly inclined and with ledges, which drops into a chamber about 8 metres in diameter, with large fallen blocks, from which two branches emerge diametrically opposite; one of them is a crawlway that begins at the foot of the entrance shaft and heads towards cave no. 2 (without connecting to it), while the other ascends among blocks and climbs to the beginning of what we could call the main gallery, formed by an elongated chamber with a flat ceiling, structured in a SE-NW direction, ending on the opposite side above a fairly steep chamber.

The floor of the gallery and chamber described is formed by cemented blocks and sediments, presenting an irregular configuration with several small chambers and lateral diverticula. Between the blocks different conduits open up, which in the form of shafts or small galleries allow access to lower corridors and small chambers.

The significant clastic morphology dominant throughout the entire cavity gives rise to a multitude of possible routes through the same conduits. This could lead some cave surveyor to assess the total length of the cave very optimistically, which could double or even triple it. In principle, we catalogue it with the 110 metres that Joan Borràs gave in his survey and which seems quite correct.
