Cova de Rotgers R-1

The entrance opens inside a doline that has formed at the base of a torrent. The access presents a steep slope, and when the ground is wet it is advisable to rig a rope. The inner entrance presents itself as a large overhang and with a downward slope from its start. The dimensions of the passage gradually diminish on the descent, until it becomes impenetrable in a narrow squeeze partially flooded at the -26 m level.

The outer torrent has deepened the entrance doline below the access overhang to the cave; water seeps through this point in the rainy season, but it becomes impenetrable within a few metres; part of the water that seeps through this point reappears by filtration in the final squeeze.

Throughout 2025 Juli Serrano, Montse Roca (SIE-CEA), Francesc Rubinat (ERE-CEC), Nil Hosta and Tanit Sanmartin carry out a survey revision and several diggings both in R-1 and in R-2 and R-3, observing that there is no possibility of a connection between the two cavities, since the closest point of R-2 with respect to R-1 is 23 metres away in a SW direction, and, most decisively, the final point of R-2 in the direction of R-1 lies at +8 metres in height above the final level of R-1, which is why communication between the two cavities is not considered feasible.
