Le d\u00e9but de la descente se fait dans des puits de dimensions modestes, qui s&rsquo;\u00e9largissent subitement \u00e0 quelques m\u00e8tres du d\u00e9part du P90, la fin de la descente est majestueuse.<\/p>\n\n\n\n<p>Ayant emport\u00e9 un analyseur O2 et un analyseur CO2, nous surveillons r\u00e9guli\u00e8rement les taux de gaz. D\u00e8s le d\u00e9but de la descente, le taux de CO2 avoisine les 2% pour atteindre 2.5% \u00e0 la base des puits.<\/p>\n\n\n\n<p>La suite de la progression se fait dans des galeries aux volumes impressionnants. Nous arrivons rapidement \u00e0 une grande coul\u00e9e, qui marque la division du r\u00e9seau en 2 galeries.<\/p>\n\n\n\n<p>Nous prenons la galerie sur notre gauche, la progression est entrecoup\u00e9e d&rsquo;imposants gours. Apr\u00e8s un premier ressaut de quelques m\u00e8tres, nous arrivons au m\u00e9andre de la chauve souris: un squelette de chauve souris calcifi\u00e9 se trouve \u00e0 quelques dizaines de m\u00e8tres du d\u00e9but du m\u00e9andre.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6a0500fd6c1dc&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6a0500fd6c1dc\" class=\"wp-block-image size-large wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"769\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" data-id=\"569\" src=\"https:\/\/gnd.catdiver.fr\/wp-content\/uploads\/2024\/06\/WhatsApp-Image-2024-06-09-a-10.14.32_0dcbda59-1024x769.jpg\" alt=\"\" class=\"wp-image-569\" srcset=\"https:\/\/gnd.catdiver.fr\/wp-content\/uploads\/2024\/06\/WhatsApp-Image-2024-06-09-a-10.14.32_0dcbda59-1024x769.jpg 1024w, https:\/\/gnd.catdiver.fr\/wp-content\/uploads\/2024\/06\/WhatsApp-Image-2024-06-09-a-10.14.32_0dcbda59-300x225.jpg 300w, https:\/\/gnd.catdiver.fr\/wp-content\/uploads\/2024\/06\/WhatsApp-Image-2024-06-09-a-10.14.32_0dcbda59-2000x1501.jpg 2000w, https:\/\/gnd.catdiver.fr\/wp-content\/uploads\/2024\/06\/WhatsApp-Image-2024-06-09-a-10.14.32_0dcbda59.jpg 2048w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"Agrandir\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Gours<\/figcaption><\/figure>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;6a0500fd6c512&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"6a0500fd6c512\" class=\"wp-block-image size-large wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"769\" height=\"1024\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" data-id=\"568\" src=\"https:\/\/gnd.catdiver.fr\/wp-content\/uploads\/2024\/06\/WhatsApp-Image-2024-06-09-a-10.14.33_8a4b6423-769x1024.jpg\" alt=\"\" class=\"wp-image-568\" srcset=\"https:\/\/gnd.catdiver.fr\/wp-content\/uploads\/2024\/06\/WhatsApp-Image-2024-06-09-a-10.14.33_8a4b6423-769x1024.jpg 769w, https:\/\/gnd.catdiver.fr\/wp-content\/uploads\/2024\/06\/WhatsApp-Image-2024-06-09-a-10.14.33_8a4b6423-225x300.jpg 225w, https:\/\/gnd.catdiver.fr\/wp-content\/uploads\/2024\/06\/WhatsApp-Image-2024-06-09-a-10.14.33_8a4b6423.jpg 1201w\" sizes=\"auto, (max-width: 769px) 100vw, 769px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"Agrandir\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><figcaption class=\"wp-element-caption\">Chauve souris calcifi\u00e9e<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<p>Nous revenons \u00e0 l&rsquo;intersection du pilier pour partir dans la seconde galerie: la galerie blanche.
