"The flora is remarkably different from the surface, like melaleucas, which are the biggest trees in the Pilbara. You just don"t get it on the surface, you only ever see them in creek beds. Then there [are] the delicate ferns, moss and the big leaf fig tree (pictured above). It"s such a contrast, in and out of the gorge."
