Entrance location

Posted by Domi le webmaster
Date 30 Aug 17, 12:23
La cavité est un peu délicate à trouver et l’usage d’un GPS est utile mais pas impératif. Consulter cependant préalablement la carte IGN 1/25 000° 2642 ET Saint Guilhem le Désert Cirque de Navacelles et Géoportail. De Ganges, se diriger vers le sud en direction de Brissac et de Saint Guilhem le Désert via la D4. Au dernier rond-point de Cazilhac, se diriger vers Cazilhac le Haut puis emprunter une petite route goudronnée étroite, la D 4E9 sur environ 2,5 km jusqu’à une piste empierrée sur la gauche montant sur la Séranne. Cette piste est carrossable pour tout véhicule car elle est utilisée par les parapentistes, bien qu’un peu ravinée par les pluies, imposant une conduite prudente et lente. Après environ 5,7 km, on trouve sur la gauche une amorce de piste sans suite juste avant un poteau en bois avec une plaque métallique et le numéro 103. Il est impossible à manquer car un gros cairn est bien visible à côté. Ses coordonnées WGS84 sont 43,87632N 3,66034E. Garer là son véhicule.

Suivre les cairns bien visibles que nous avons confortés et augmentés. À une dizaine de mètres du poteau 103, il faut franchir un mince rideau de végétation peu dense pour trouver les cairns suivants. On progresse globalement vers le sud dans une succession de clairières de lapiaz et petits blocs où la progression est facile. On débouche enfin sur une vaste clairière où le dernier cairn est proche de la cavité, dissimulée dans une dépression emplie d’arbres. L’orifice du puits est un peu dissimulé par la végétation. Ses coordonnées WGS84 sont d’après Grottocenter et d’après Iphigénie donc quasiment les mêmes. Iphigénie indique 43,87523N 3,66094E. Le cheminement depuis le poteau 103 est de 220 m.

Cave entrance descriptions

Description partielle (par Jef)

L’éboulis à la base du puits contient quelques ossements. Il descend vers le nord. Un gros pilier mérite photo tout comme les concrétions qui décorent la galerie qui fait suite. Peu détériorée, elle se termine sur un point bas terreux. On pourrait découvrir divers points de vue en escaladant les concrétions mais cela risquerait de les salir inutilement.

À la base du puits, on peut parcourir un diverticule descendant où on trouve un squelette de ruminant. Nous n’avons pas escaladé la cheminée étroite qui conduit à une petite suite.

La salle à l’opposé du puits a quelques diverticules limités. Sur un côté, on escalade assez facilement une grande coulée de calcite qui conduit à un colmatage bien concrétionné.
