Roraima is the highest tepui in the Gran Sabana, towering 2,810 metres (9,000 feet) above the plains. Pemon legend variously describes Roraima as the Mother of All Waters and the home of the Goddess Kuín, grandmother of all Men . I am surrounded by amphitheaters of rock, carved over millennia by the unforgiving rains and winds. Faces and animals and creatures emerge in their strange, other-worldly shapes, while sweeps of cloud close in all around you, then disappear. My only bearings are the faint paths of rubbed-away lighter rock, the footsteps of all the other trekkers who overcome before me.
