Nous d\u00e9collons tranquillement du Puy \u2013 halte charcuterie \u00e0 Langogne. Vers 10H30 nous sommes chez Sophie, Antoine et Jeremy \u00e0 St Julien du Tournel. Nous papotons jusqu\u2019\u00e0 l\u2019heure de l\u2019ap\u00e9ro. Apr\u00e8s un tr\u00e8s bon d\u00e9jeuner, nous attaquons notre p\u00e9riple avec le 4 x 4 de Jeremy. Nous allons directement \u00e0 la grotte du tunnel de l\u2019Altaret, cette cavit\u00e9 d\u2019une vingtaine de m\u00e8tres (voir lien ci-dessous) nous interpelle toujours quant \u00e0 son am\u00e9nagement\u00a0! Il y a un petit actif. Pr\u00e9sence d\u2019un petit rhinolophe. Christophe et J\u00e9r\u00e9my s\u2019acharnent sur le mur du fond \u2013 pendant ce temps, je fais sauter manuellement un petit verrou (colmatage artificiel) o\u00f9 l\u2019actif s\u2019engouffre dans une fracture verticale, Jeremy reprend le travail de fa\u00e7on plus \u00e9nergique, pour extraire un bloc. Ensuite il s\u2019acharne sur un bloc plus important. A poursuivre avec des moyens plus percutants. Apr\u00e8s 2 bonnes heures de travail \u00e0 la massette et burin\/broche, nous quittons les lieux sous une froide temp\u00eate de neige.<\/p>\n

Ensuite Jeremy nous guide \u00e0 l\u2019entr\u00e9e d\u2019un aven dans une ancienne carri\u00e8re au-dessus du village de Sainte-H\u00e9l\u00e8ne. Le trou s\u2019ouvre sur une facture, en dessous c\u2019est vaste et n\u00e9cessite un \u00e9quipement correct, un arbre permet de faire une main-courante, et une barre en-travers de l\u2019orifice de descendre plein but\u00a0! Un grillage prot\u00e8ge l\u2019entr\u00e9e. On reviendra demain avec le matos n\u00e9cessaire.<\/p>\n

Un peu plus en aval, nous arr\u00eatons \u00e0 un captage en bordure gauche de la route, le d\u00e9bit est de 20 \u00e0 30 l\/s, une vingtaine de m\u00e8tres plus haut s\u2019ouvre 2 petits trous, apr\u00e8s avoir d\u00e9stabilis\u00e9 quelques blocs instables, Christophe progresse d\u2019une dizaine de m\u00e8tres, cela ressemble \u00e0 une faille de d\u00e9collement. Ensuite nous passons c\u00f4t\u00e9 grotte de Sainte-H\u00e9l\u00e8ne, en rive droite du Lot \u2013 Jeremy y a rep\u00e9r\u00e9 une sortie d\u2019eau sous le chemin et quelques trous de blaireaux.<\/p>\n

Nous rentrons \u00e0 la tomb\u00e9e de la nuit. Sophie nous a pr\u00e9par\u00e9 un excellent repas avec des produits locaux.<\/p>\n

Le dimanche matin, il neige \u00e0 gros flocons. Apr\u00e8s avoir \u00e9pluch\u00e9 la doc que j\u2019ai amen\u00e9 et \u00e9tabli un petit programme avec notre \u00ab\u00a0gratteur local\u00a0\u00bb, nous quittons les lieux sous la neige, elle nous accompagnera jusqu\u2019\u00e0 Pradelles.<\/p>\n
