Pozzo A-7 di Piaggia Bella

The cave is formed along an evident fissure descending from the Ballaur. The large meander below continues at a steep gradient through various small drops down to an evident tectonic fracture; in this, a series of demanding narrow passages alternating with a couple of small shafts bring the known part to a depth of 73 m as per the survey. The umpteenth narrow passage, which currently constitutes the limit of the cave, is passable.

The initial part has been known since forever, but only in summer '83 was it possible to locate the large meander below thanks to a shrewd clearance operation. The presence of an air current (from the lower entrance) testifies to the connection with the Gola del Visconte, presumably in the still unknown region between the part explored in the Gola, the Sala Chiabrera and the Gallerie Rousseau. It was the far more enticing prospects of the Gola del Visconte that distracted the explorers from the narrow passage.
