   Simonnot G, 2016 and Simonnot G, 2018 has the ETRS89 grid reference as 0450832 4792841.

   Immediately to the north of the Rotura hut, the chestnut tree-surrounded entrance is marked SCD2014 and has a cool draught. A pitch of 8m drops to a meandering stream passage. The second pitch of 10m enters some nice sandy-floored chambers. The draught appears to be going over all these pitches but a major bolt traverse is needed.  On the left at the bottom, a hole at head-height leads to a rift. A visit in warmer weather is needed to see if there is a draught.
   The site was explored by the Spéléo-Club Dijon in 1988 with a survey and some work at the base carried out in 2015.

The information below has been roughly translated from the French, Spéléo-Club Dijon reference, Simonnot G, 2016.
   Immediately north of the cabin of Rotura, at the bottom of a depression surrounded by chestnut trees. (The same access as to the Torca de Rotura (MCP0753 / SCD2013).
At the end of a steep wooded doline (-5m) starts a bend which we reached the bottom by a P.8. Then a 15m tube, chaotic but comfortable, broken down small drop. Two passages enter on the right side and a third on the left that requires climbing. Returning to the main passage, another pitch (p7) drops into a beautiful rotunda of five meters in diameter; it turns out unfortunately clogged with the remains of an imposing fill at -29m.
A conduit back (arrival) is grafted to this small room. Only an opening in the fill helps maintain a slim hope.
