Descrizione
Morfologia
At the bottom of a doline about 3 metres in diameter opens the mouth of the pit, which gives access to a shaft 35 metres deep, subdivided into two sections (P.12 and P.23) by a wide ledge. At its base, a steeply inclined ramp between clastic materials leads us to a small step that gives onto a final chamber with a terminal chimney.
Storia
The first exploration was carried out by N. Font i Sagué on 13 August 1898, although having descended more than half the shaft he found himself short of air and had to abandon the descent. Twenty-six years had to pass for the pit to be visited again. On 7 August 1924 it was the objective of the group led by Amat i Carreras who, knowing Font's experience, took all precautions and managed to explore it completely. He deduced that the presence of carbon dioxide was due to the presence of a multitude of carcasses of different animals. It should be said that this pit, until not long ago, was a preferred place for throwing all kinds of dead animals from the nearby farmhouses. We do not know if this bad habit still continues, but it is true that in recent years some problem of hypoxia has been detected.
