LES COMPAGNONS DE LA NUIT MINÉRALE

The Companions of the Mineral Night are based in Senlis (Oise) and are very active in Picardie and in the karst mountains of France in Ardèche, Vercors, Alps and abroad (Spain, Crete). In addition to exiting and training (in an open-pit career for the latter), members meet monthly around photo projections and exchanges on past and future outflows. Excursions to discover the underground world are organized regularly in cavities of Oise.
