Cavity with a scree ramp, a rocky crawl, a river chamber and meanders with tributaries, explored in 2003 by the G.E.O in Abaurrea.
Descrizione
Morfologia
The cavity opens by way of a very steep ramp of scree cone. After a rocky crawl you reach the river chamber. Upstream, after some crawls, the meander becomes wider until reaching genuinely comfortable sections. The gallery closes in a narrow, impassable passage.
Idrologia
In the river chamber, on the right, the river reappears, and after a meander with a floor collapse it disappears. Upstream several tributaries are observed. From the narrow passage that closes the gallery flows the water coming from an upper sinkhole.
Progressione
Access is by way of a very steep ramp of scree cone; then, after a rocky crawl, you reach the river chamber. A mud chimney allows access to the upper level, but it is hardly passable due to the large accumulation of clay.
