Les Chaudi\u00e8res d’Enfer sont deux exurgences temporaires des sources de la Lionne. Ces deux grottes se terminaient sur des siphons. Lors des crues un d\u00e9bit impressionnant sort de la petite Chaudi\u00e8re, tandis que la Grande ne coule qu’exceptionnellement. Elle a coul\u00e9 pour la derni\u00e8re fois durant la fameuse crue de 1990. Des l\u00e9gendes se rapportent au d\u00e9veloppement du \u00ab\u00a0r\u00e9seau\u00a0\u00bb de la Lionne ainsi qu’\u00e0 une rivi\u00e8re souterraine!<\/p>\n

Jusqu’\u00e0 la fin de l’ann\u00e9e 1999, toutes les cavit\u00e9s des sources de la Lionne butaient sur des siphons. Un grand espoir de continuation se trouvait derri\u00e8re les siphons des petites et Grandes Chaudi\u00e8res d’Enfer (Baron en parle sans son ouvrage \u00ab\u00a0Sp\u00e9l\u00e9ologie du canton de Vaud\u00a0\u00bb); c’est pour cela que nous avons proc\u00e9d\u00e9 au pompage de la Grande Chaudi\u00e8re. D\u00e8s que le siphon fut vid\u00e9, un courant d’air net et constant traversa la cavit\u00e9. Un nouveau r\u00e9seau \u00e9tait n\u00e9 ! \ud83d\ude42<\/p>\n

Une galerie descendante o\u00f9 une corde est conseill\u00e9e m\u00e8ne \u00e0 une chati\u00e8re. Derri\u00e8re se trouve une petite salle avec \u00ab\u00a0LE\u00a0\u00bb siphon. Une fois vid\u00e9, il est possible de remonter entre des blocs dans une nouvelle salle. De la un nouveau siphon et un passage \u00e9troit en hauteur m\u00e8ne \u00e0 un petit lac qu’il faut traverser. De l\u00e0 part une imposante galerie ultra glaiseuse dont l’exploration s’est arr\u00eat\u00e9e sur des siphons. Mais o\u00f9 passe donc le courant d’air omnipr\u00e9sent dans la premi\u00e8re partie? Vu le puissant courant d’air, il doit y avoir une entr\u00e9e sup\u00e9rieure. C’est certain…<\/p>\n
