Simonnot G, 2016 has the position as ETRS89 0450999 4792821.
A large shaft, rather like Rowten without the stream, labelled SCD2013.
A 45m pitch has a ledge 20m down and lands on a rock slope. A steep boulder slope leads to a broken 15m pitch and a final 20m pitch to a sandy floored chamber where a 10cm wide fissure emits a cold draught. This is above Smelly Hat Aven in Cueva Vallina and a start has been made to open up the rift (February 2018).
The information below has been roughly translated from the French, Spéléo-Club de Dijon reference, Degouve de Nuncques Patrick et Simonnot Guy, 1989 (in Sous le Plancher, no 4, 1989), repeated in Simonnot G, 2016. The French reference number for this site is SCD2013.
In the side of a small valley to the north of Arredondo, on a sloping moor, fifty meters above a hut. Easy access by road then along the track of Llaneces. At the end, taking a path along the hillside for ten minutes towards the hut of Rotura reaches the site. Explored in October 1988.
A pretty p48 is followed by shorter verticals (p20; p5) leading down to -73 in a small choked chamber. A narrow fissure emits a violent draught. This hole could be the source of Fuentes (No 2018). (Site 1756).
This chasm must be in relation with the cueva Vallina whose galleries pass just below. (Simonnot G, 2018)
