9.1 Antsarahaso Maze

A large karst area, the Analamera, extends northeast of the Ankarana Plateau. Recent exploration northeast of the Ankarana Plateau, led by the French caver J. C. Dobrilla, has indicated important speleological potential. He found an incredible maze, the Antsarahaso, whose length of 20 km makes it the third longest cave in Madagascar (Fig. 9.1).
