Discovered and explored by members of the AJSC speleology section (La Courneuve, FR) on 25 August 1972. There had never been any news of the activities of this French group, carried out on both sides of the border during the summers of 1971 and 1972, until last 13 October 2018 (after coinciding in the area, in the summer of 2018, with a Franco-Belgian group carrying out a campaign) when our colleagues Josep Guarro and Joan Carles Juderías made a tour of the area. Josep was able to locate a member of that group and gave him a copy of the report of their activities, which he has kindly ceded to us so that we can include some unpublished cavities of the Liat area in Espeleoíndex. Only three of them seem to be of minimal interest and accompany the survey; the rest are very small and some practically impenetrable.
