Angel Falls in Venezuela is the tallest waterfall in the world, as well as the tallest single drop in the world. It is also one of the most beautiful clearly as these pictures and videos show. Here is the full version of the video from BBC Planet Earth
The falls consist of a 2,648 foot plunge, where the water comes out of the face of Auyan Tepui, then it cascades down steep talus before dropping over another 100 foot cascade. No one seems to know what the stream the falls occur on is called.
For centuries, there have been references to Angel Falls being known in Pemon (the local language) as Churún Merú, and the falls subsequently being on Rio Churún. However, the real Pemon name of the falls is Kerepakupai Merú, which means “fall from the deepest place”.
To further clear this issue, Churún Merú is a totally different waterfall of about half the height of Angel Falls, located further up the large canyon by-secting Auyan Tepui. The top of the Tepui from which the falls drop is heavily fractured and jointed sandstone.
The waters above the falls drop into a series of cracks, crevices, and gorges and burst out of the cliff face about 50 feet below the brink. The waterfall segments in periods of highest water.
Pilot Jimmy Angel is widely credited for discovering the falls in 1937, but the true discoverer was one Ernesto de Santa Cruz, who found the falls in 1910. The falls were subsequently named for Jimmy Angel, since he was the first westerner to view the falls.
