Avencots dels Motllats de la Pona

It is a group of fissures produced when the north-eastern cliff of the Motllats de la Pona tilted over the barranc de Mas del Panxo. These fissures follow a fracture line running SE to NW and have 6 entrances, although only number 1 ("Avenc del "Neng""), located at the NW end, and number 2, located at the SE end, are feasible to access; even so, by rappel one can access from any point of the fissures. The remaining entrances give onto a wild forest and cliffs that are difficult to overcome.

The group has a main fissure and a second parallel fissure that intersect each other via secondary fissures perpendicular to the former; this entire group has a length of 1009.76 metres, while the lowest point is at -44.61 metres.

Just above entrance number 2, we find another fissure parallel to the previous ones with three branches and which forms part of the group, but as happens in other large nearby fissures similar to this one, it does not physically connect with the rest of the fissures. This last section has a length of 168.50 metres, with which the group totals a length of 1178.26 metres.

From entrance number 1 ("Avenc del "Neng"") and entrance number 2 one can access the group; by rappel one can access from any point of the fissures.
