A pit 14 metres deep in Vallirana.

Caratteristiche

Località

By the road that from Begues climbs to the “Punt Sud” power plant located at the Pla de Basses Roses, once we are level with the Pla del Cirerer a path comes out on the right that goes towards the Pla d'Ardenya; at the point where the path passes underneath and right next to an electricity pylon, already in the Pla de Sot d'Óssos, we must take a path on the left that in a few metres will lead us to a large doline in the very middle of which is the avenc Gran de les Alzines; 5 metres to the NE we find the tiny mouth of the esquerda de les Alzines.

Descrizione

Morfologia

A little more than -4 metres deep the initial small shaft bifurcates, one of the branches ends at -9'50 metres, the other reaches a narrow four-shaped laminador at -9 metres from the mouth, from here another 5 metres, quite narrow, can be descended, placing us at -14 metres. The cavity seems to continue but extremely narrow.

Storia

The first exploration was carried out by the GES del CMB down to a depth of -7 metres.

With the desobstruction of the nearby avenc Gran de les Alzines, it was thought that the esquerda became part of the previous cavity; later, once the area had been cleaned, it was observed that the esquerda was still there.
