Avenc Nº1 de l'Esquerda

The mouth of the pothole is 10 metres long by 0.9 wide and opens the way to a shaft divided in two by some blocks, the floor being at -19 and -9 respectively. Via the P-19 one reaches a descending floor covered with small blocks, until reaching the point of maximum depth of the cavity, -32 metres. Via the P-9 we find a floor identical to the previous one but wider; after 8 metres of passage a very irregularly shaped shaft opens, -10 metres deep, semi-obstructed by blocks; among them one can access a 7-metre shaft with no continuation. Situated again on the floor of the P-10, a gallery is visible at the other end; to access it one must climb up some blocks, after some successive steps of 2 and 3 metres, it links with a rectangular room of 7X2 metres, the ceiling is formed by the accumulation of large blocks. At the upper end of the room we find a flat crawlway through which one accesses a second room of 5X2 metres; in this room we find two continuations, one by means of a crawlway that ends after a few metres, and the other through an inclined shaft -13 metres deep that ends obstructed by earth and blocks coming from the upper zone.
