Plus pr\u00e8s des \u00e9toiles, les alpinistes qui gravissent l’Everest prennent parfois le temps de contempler la Voie lact\u00e9e dans un ciel noir comme de l’encre.<\/strong><\/p>\n

Plus haut sommet du monde, l’Everest (8.848 m\u00e8tres au-dessus du niveau de la mer) fait partie de la cha\u00eene de montagnes de l’Himalaya qui marque la fronti\u00e8re entre la Chine et le N\u00e9pal. Le 29 mai 1953 l’alpiniste et explorateur n\u00e9o-z\u00e9landais Edmund Hillary parvenait pour la premi\u00e8re fois \u00e0 atteindre son sommet avec \u00e0 ses c\u00f4t\u00e9s\u00a0 le sherpa n\u00e9palais d’origine tib\u00e9taine Tensing Norgay. Depuis plus de soixante ans les alpinistes ne cessent de rivaliser d’audace pour atteindre le sommet toujours plus vite en empruntant de nouvelles voies, avec ou sans assistance respiratoire.<\/p>\n

Une ascension du mont Everest s’\u00e9talant sur plusieurs semaines, elle se fait par \u00e9tapes successives. C’est au camp de base (5.340 m\u00e8tres) qu’est rassembl\u00e9\u00a0l’ensemble du mat\u00e9riel achemin\u00e9 par des\u00a0 porteurs et des yacks. Une fois les alpinistes acclimat\u00e9s \u00e0 l’altitude, l’ascension se fait par paliers : camp 1 vers 5.900 m\u00e8tres, camp 2 vers 6.500 m\u00e8tres, camp 3 vers 7.200 m\u00e8tres, camp 4 vers 8.000 m\u00e8tres d’o\u00f9 partira l’assaut final.<\/p>\n

Ces camps permettent aux grimpeurs de s’acclimater progressivement \u00e0 l’altitude (il n’est pas rare de les voir redescendre \u00e0 un camp inf\u00e9rieur s’ils ne se sentent pas en assez bonne condition pour reprendre l’ascension). Loin de toute pollution lumineuse<\/a>, ces haltes sont une belle occasion pour prendre le temps d’admirer la Voie lact\u00e9e<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
