waterfall in the Guiana Highlands in Bolívar state, southeastern Venezuela, on the Churún River, a tributary of the Caroní, 160 miles (260 km) southeast of Ciudad Bolívar. The highest waterfall in the world, the cataract drops 3,212 feet (979 metres) and is 500 feet (150 metres) wide at the base. It leaps from a flat-topped plateau, Auyán-Tepuí (“Devils Mountain”), barely making contact with the sheer face. The falls, discovered in 1935, were named for James Angel, an American adventurer who crash-landed his plane on a nearby mesa in 1937. Because of the dense jungle surrounding the falls, they are best seen from the air.
