The deepest known cave in the world is the Gouffre Berger near Grenoble. It extends to a depth of 3,723 feet. This immense chasm has been formed by an underground stream which has tunneled a course through a flaw in the rocks. The entrance to the cave is on a plateau in the Dauphine Alps. As it is only six feet across, it is barely noticeable. The cave might never have been discovered has not the entrance been spotted by the distinguished French pot-holer, Berger. Since its discovery, it has become a sort of potholers' Everest. Though a number of descents have been made, much of it still remains to be explored.

? ? A team of pot-holers recently went down the Gouffre Berger. After entering the narrow gap on the plateau, they climbed down the steep sides of the cave until they came to narrow corridor. They had to edge their way along this, sometimes wading across shallow streams, or swimming across deep pools. Suddenly they came to a waterfall which dropped into an underground lake at the bottom of the cave.

世界上最深的洞穴是格里諾布爾附近的高弗.伯杰洞，深達(dá)3,723英尺。這個(gè)深邃的洞穴是由一條地下暗泉沖刷巖石中的縫隙并使之慢慢變大而形成的。此洞的洞口在丹芬阿爾卑斯山的高原上，僅6英尺寬，很難被發(fā)現(xiàn)。若不是法國(guó)著名洞穴探險(xiǎn)家伯杰由于偶然的機(jī)會(huì)發(fā)現(xiàn)了這個(gè)洞口的話，這個(gè)洞也許不會(huì)為人所知。自從被發(fā)現(xiàn)以后，這個(gè)洞成了洞穴探險(xiǎn)者的珠穆朗瑪峰，人們多次進(jìn)入洞內(nèi)探險(xiǎn)，但至今尚有不少東西有待勘探。

? ? 最近，一隊(duì)洞穴探險(xiǎn)者下到了高弗.伯杰洞里。他們從高原上的窄縫進(jìn)去，順著筆直陡峭的洞壁往下爬。來(lái)到一條狹窄的走廊上。他們不得不側(cè)著身子往前走，有時(shí)過(guò)淺溪，有時(shí)游過(guò)深潭。突然，他們來(lái)到一道瀑布前，那瀑布奔瀉而下，注入洞底一處地下湖里。
