Esquerda del Graller

This is a tectonic cavity produced by the movement of attraction towards the void at the western end of the south crag of the barranc de la Pardina. The main fissure opens to the outside for about sixty metres with an average width of a metre and a half. Via its western end and at the foot of the crag it is possible to reach a lower level of the fissure, which descends steeply until it connects with another fissure with a NW-SE orientation; following it in a NW direction, it narrows until it becomes impenetrable. Entering through the upper fissure it is possible to progress from west to east for some 55 metres, at which point it meets a joint with a SW-NW orientation, whose floor lies some 10 metres below.

Entering through the upper fissure it is possible to progress from west to east for some 55 metres, at which point it meets a joint with a SW-NW orientation, whose floor lies some 10 metres below. Once the vertical section has been overcome, it is possible to continue towards the NW where, after a narrow passage, the gallery leads us to a point where it merges with the lower part of the cavity.
