Cova de la Mosquera

The cave has two openings; one of them, the larger one, is artificial, and both are connected by a short, low gallery. The vertical range of the cavity is 20 metres (+19/-1).

From the natural opening a gallery begins that follows the little river upstream; in some places the gallery loses height due to abundant sedimentation, causing the gallery to flood. It gains width where it joins the gallery coming from the artificial entrance. A stretch without water follows until a chamber where a conduit coming from the artificial entrance converges; 40 metres further on we find the river again, shallow but occupying the entire width of the gallery. The gallery turns 90º, producing a new pool while the width of the gallery decreases. The water flows again through an impenetrable zone, but a small side conduit allows the river to be found again at various points, until reaching a small chamber of clastic origin occupied by a significant quantity of water. Following the course of the river through a narrow gallery we reach a point where the water emerges through a bedding joint with no possibility of continuation.

Returning to the main gallery, it bifurcates about 25 metres on and the river is found again; a low-roofed stretch follows. After this one reaches the most important sector of the cave as regards its volume, until arriving at a chaos of blocks where the regularity of the gallery is broken, while the height of the ceiling diminishes. Further on, on the left, one reaches a fossil gallery at a higher level, which connects at various points with the lower gallery, meeting it again 70 metres further on. From here one reaches the final sector of the cave, characterised by important clastic processes that form a false upper floor and where, via a chimney, one can reach the highest part of the cavity.

An interesting but contaminated cave with 962 metres of passage in Beuda.
