Avenc de l'Aisling

The cavity gains depth through the narrow ramp passage that we left while downclimbing the first step. Through here we quickly reach the lower part of the transverse fissure of the first level. One can downclimb a -4 metre step and we find ourselves in the sala de la Distribució. This room is formed by different levels, at its base we descend a few metres to the right by an evident continuation and access the sector of Sortida Primer Dia.

From the base of the pou dels 4 spits, another gallery forms a step marked by large blocks, once down again at the fissure, a discreet continuation is seen, since the gallery continues ascending; one must make a small opposition move, along this return route of the Grans Espais. Through the discreet continuation, we bypass blocks without difficulty until a new ascending passage that brings us in front of a large block. The crawling passage skirts this block on the right, a large volume appearing before us. The dimensions are already considerable, not long after it forms a balcony, if we descend we calmly reach the lower galleries of the Grans Espais until the end. On the other hand, by a small ledge on the right we can position ourselves on an intermediate level of blocks, where the darkness of the upper part can be seen. One must look for the most evident manoeuvres to climb to the upper sector of the Grans Espais.

From the mouth of the avenc de l'Aisling, we downclimb a step that places us on the upper level, immediately to the left we find a narrow ramp that communicates with the lower part. Progressing along the main fissure, it is quickly cut by a new fissure that on its right and through a narrow pit, would also take us into the lower levels. Again in the main fissure, on its opposite side it continues a few metres until seeing the light of one of the wall mouths that is a few metres above, shortly before a new fissure takes us to a room where entering by one side we access the exterior. From the intersection of the first two upper fissures, the fissure between embedded blocks, we reach an ascending ramp and the upper mouth. On the other side of the ramp there is a small pit with no further continuation.

This sector begins progressing between blocks that change the direction occupying the fissure, until overcoming a narrow passage without difficulty and it pours us into a wide gallery that is again cut almost perpendicularly. To the left we would reach the sala Cega, end of this progression. To the right at a new intersection, the pous del Ganivet, of -8 metres. This high and narrow fissure we will find again later, continuing above the Ganivet. A zone of false floors changes the direction again, to the right it leads us to a clean fissure that connects with a new turn to the right with a gallery blocked by a pile of blocks. On one side, between the main block below and the wall, we link up, closing the circuit with the high and narrow diaclase that comes from the pous del Ganivet. One must climb some 7 metres to reach a new upper room. Progressing handrail along the earthy ledge of the lower gallery, a narrow passage makes entry into a new network of fissures difficult and comfortably places us in a small room where through a laminator if it is daytime, the exterior light can be seen at the back. To the right we find a blind pit. Dragging ourselves through the laminator we access a wide gallery, at the two ends of which we find the two mouths of Sortida Primer Dia.

We quickly gain height through the sala de la Distribució and reach a new room called del Llaminador, whose name comes from a wide laminator that passes under a bedding joint. At the end it leads us to a wide fissure and to a -7 metre step pou dels 4 spits. To continue the progression we would have to descend a pit, but there is a passage, in the very middle of the sala del laminador, that descending between blocks connects with el Racó and through here with the base of the pou dels 4 spits. There are other connections to the room, through a pit we would connect with the lower part of the sala de la Distribució, and on the left a fourth gallery of no further importance with a blind pit of -10.5 metres, el Fanguer Maleït.

Now we turn back along this level, a new and wider laminator, also formed by the bedding joint, leads us to a room of steep slope with its limit very full of blocks. To the left, after moving some of the boulders, lying on the ground we reach a small room of descending continuation, and we recognise the place through which we have passed before, we are at the other gallery that comes from the pou dels 4 spits.
