"The 250 km long Bemaraha Plateau, composed of mid-Jurassic (approximately 200 mya) limestone of marine origin (Du Puy and Moat 1996), is heavily eroded into a karst landscape characterized by networks of deep crevasses, underground rivers and caves, separated by spectacular pinnacles of limestone, up to 100 m high, forming a “forest of sharp stones”" (IUCN outlook 2020)
