Amazing World - Armand Cave
Armand Cave - France
In 1897, the French potholer Louis Armand, exploring in the limestone hills of Cevennes 50 miles north-west of Montpellier, discovered the deep cavern later named after him. After making his way down a vertical shaft 246ft deep, entered a vast chamber, now known as La Grande Salle, which measures 330 by 180ft. The floor is covered with what has been described as a "forest" of stalagmites, formed from the percolation of water through the roof of the cave; the tallest of these is 100ft high.
