Avenc de les Casetes

Wide entrance open between two large masses of rock; from the upper lip one can descend 12 metres. From the lower lip, a descending ramp with small steps leads onto a somewhat delicate traverse. An ascending gallery of square section ends in a room measuring 4x3x2 metres with a flat ceiling and a floor covered with blocks. A 3-metre step open between unstable blocks leads to the start of a ramp of modest section. The dimensions decrease as one descends until reaching an impenetrable zone. An accumulation of blocks closes the passage, at the base of a new step, where light from outside enters. A descending joint of a few metres, located about 10 metres below the entrance, allows one to descend to these blocks from outside.

From the lower lip, a descending ramp with small steps leads onto a somewhat delicate traverse, to access on the right an ascending gallery of square section. Once back on the previous traverse, one descends a 3-metre step open between unstable blocks, which leads to the start of a ramp of modest section. In opposition, one climbs up on the left to access a window through which the gallery continues.
