Les Avens de Caussole et Calern, Voyage au centre de la terre<\/h2>\n

Le plateau de Calern rec\u00e8le bien des secrets. Au d\u00e9but du parcours, ce sont les avens Alain et du Perchoir qui sont visit\u00e9s.<\/p>\n

L’eau a creus\u00e9 ces formidables trous o\u00f9 nombres de sp\u00e9l\u00e9ologues ont explor\u00e9 les galeries. Le plateau calcaire du Jurassique s’ouvre en failles impressionnantes. Le sentier serpente entre zones de lapiaz, terrains herbeux et dolines curieuses.<\/p>\n

Nous d\u00e9jeunons au pied de l’embut  (vient du mot entonnoir), faille tr\u00e8s impressionnante o\u00f9 la rivi\u00e8re se perd dans les entrailles de la terre.<\/p>\n

L’eau serpente le long de la plaine (appel\u00e9 aussi polj\u00e9), puis se perd dans le ponor (orifice naturel situ\u00e9 au fond d’un polj\u00e9 par lequel une eau de surface dispara\u00eet (cours d’eau ou eau de pluie) et devient souterraine. Lors de forte pluie, le ponor est satur\u00e9 est satur\u00e9 et inonde le Polj\u00e9, la plaine se transforme en lac qui en 1996 a atteint la profondeur de 7.5 m !!  Ce type g\u00e9ologique existe aussi ailleurs dans le monde dans des configurations beaucoup plus vastes.<\/p>\n

Nous reprenons le sentier en rejoignant le GR4 pour monter sur le plateau de Calern via Notre Dame de Calern : une grotte am\u00e9nag\u00e9e en sanctuaire depuis 1887 (une procession a lieu le 15 a\u00f4ut). Au sommet de Calern , un dernier aven (Calernaum) est \u00ab\u00a0visit\u00e9\u00a0\u00bb avant de redescendre \u00e0 la voiture. <\/p>\n

Le plateau de Caussols alimente les eaux du loup. Une belle balade appr\u00e9ci\u00e9e sans difficult\u00e9s et riche en curiosit\u00e9s.<\/p>\n
