A previous position was ETRS89 0450908 4792309.

The information below has been roughly translated from the French, Spéléo-Club Dijon reference, Simonnot G, 2016.

In the valley of Vallina, a well marked trough abuts the foot of a outcrop representing an ancient and important sink. A 1 m excavation in October 2006 does not leave much hope as there is no airflow.
