　　With what does the writer compare the Gouffre Berger?

　　Cave exploration, or pot-holing, as it has come to be known, is a

　　relatively new sport. Perhaps it is the desire for solitude or the chance of

　　making an unexpected discovery that lures people down to the depths of the

　　earth. It is impossible to give a satisfactory explanation for a pot-holer's

　　motives. For him, caves have the same peculiar fascination which high mountains

　　have for the climber. They arouse instincts which can only be dimly

　　understood.

　　Exploring really deep caves is not a task for the Sunday afternoon rambler.

　　Such undertakings require the precise planning and foresight of military

　　operations. It can take as long as eight days to rig up rope ladders and to

　　establish supply bases before a descent can be made into a very deep cave.

　　Precautions of this sort are necessary, for it is impossible to foretell the

　　exact nature of the difficulties which will confront the pot-holer. 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 a 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. They plunged into the lake, and after loading their gear on an

　　inflatable rubber dinghy, let the current carry them to the other side. To

　　protect themselves from the icy water, they had to wear special rubber suits. At

　　the far end of the lake, they came to huge piles of rubble which had been washed

　　up by the water. In this part of the cave, they could hear an insistent booming

　　sound which they found was caused by a small waterspout shooting down into a

　　pool from the roof of the cave. Squeezing through a cleft in the rocks, the

　　pot-holers arrived at an enormous cavern, the size of a huge concert hall. After

　　switching on powerful arc lights, they saw great stalagmites -- some of them

　　over 40 feet high -- rising up like tree-trunks to meet the stalactites

　　suspended from the roof. Round about, piles of limestone glistened in all the

　　colours of the rainbow. In the eerie silence of the cavern, the only sound that

　　could be heard was made by water which dripped continuously from the high dome

　　above them.
