Avenc del Coll d'escriu

Entering through the lower entrance, of larger proportions, one descends a 9.7-metre pit; at its bottom and in a N direction, a steeply inclined ramp can be climbed, which leads directly beneath the small orifice that constitutes the upper entrance. From the base of the main entrance pit and in a descending direction, one descends a small step and then, by a ramp of debris, follows a gallery that reaches the point of maximum depth, a place where the joint narrows, becoming impenetrable.
