Wonder fall: Angel Falls, Venezuela
The Guiana Highlands extend across the northern part of South America, occupying much of southern Venezuela as well as parts of Guyana and northern Brazil. The Highlands are famous for their magnificent flat-topped mountains called tepuis (tepui meaning “house of the gods”). Auyan Tepui is the largest of these, and the world’s highest uninterrupted waterfall, Angel Falls, drops from a cleft in its summit (descending a total of 979 metres to the valley floor); in its uppermost few hundred metres, the water barely makes contact with the sheer sandstone cliffs behind. Angel Falls features in Natural Wonders of the World (DK Publishing, £30).
