It then cascades down a steep slope, over smaller falls, on its way to the Rio Churún. Upon landing, the water begins flowing over, under, and around rock debris that has fallen from the cliffs above. The vaporized water descends in a rain onto the rocks below. The rest of the water plunges a half mile to the rocks below. Much of the water vaporizes during the fall, and swirls as a mist in the turbulent air. There it begins a dramatic free-fall of 2648 feet. Just before reaching the falls, the water drops into fractures and caverns, then bursts into the air through openings below the top of the sandstone cliff. suddenly, the river drops into a fracture system, changes flow direction by 135 degrees, and accelerates through a channelized cascade of white water. The excitement begins about 500 feet from the cliff. The river meanders across the top of the Auyán-Tepuí, heading towards a cliff on its northern edge. Other water runs off and flows into tributaries of the Rio Kerepacupai Meru, the river that feeds the falls. Some of the rain soaks into the ground and enters a network of subsurface fractures and caverns beneath the Auyán-Tepuí. The air masses cool as they rise, causing water vapor to condense and fall as rain. These winds evaporate water from the ocean surface and carry it towards South America.Īs the moisture-laden air masses reach southeastern Venezuela, they rise to cross the highlands of the Auyán-Tepuí - the headwaters of Angel Falls. There, the northeasterly trade winds deliver dry air masses from the Sahara Desert of Africa. Much of the water of Angel Falls begins its journey in the Atlantic Ocean. The volume of channelized flow and how the water begins its fall will certainly vary depending upon recent weather and time of year. A minor amount of water emerges from fracture cavities. In this photo, you can also see that most of the falls' water is emerging from cavities that follow bedding planes in the massive sandstone. The next time the height of Angel Falls is surveyed, perhaps they should be considered as a potential addition to the total height? The Upper Falls: This photo is a view of the seldom-seen and generally ignored waterfalls and channelized cascades upstream from Angel Falls. On their way, evaporation from the surface of the Atlantic Ocean fills these air masses with water, which will fall as rain when they are cooled rising the eastern slope of the Auyán-Tepuí. The Northeasterly Trades: The atmospheric circulation model above shows how the Northeasterly Trade Winds deliver air masses from the arid regions of western Africa to northeastern South America. It is an indigenous name from the Pemón natives meaning "falls from the deepest place". In 2009, Hugo Chávez, President of Venezuela, declared that Kerepakupai-merú should be the country's official name for the falls. ![]() ![]() Ruth Robertson's expedition to the falls, and Perry Lowrey's survey of their height, did not occur until 1949. That name is still used for the falls in Spanish-speaking countries. On a map within the project report, the name "Salto Ángel" was printed at the location of the falls. Īngel served as a pilot and guide to the leaders of the project between 19. The first official use of Angel's name associated with the falls was on a map published in 1939 by the government of Venezuela as part of their report titled Exploración de la Gran Sabana ("Exploration of the Great Savannah"). This occurred before the height of the falls was properly measured and before the name Angel Falls was in popular use. Within a few years, Angel's story of a "mile-high waterfall" had been widely publicized through stories and trivia items in popular media. Angel Falls was named for James Angel, an American pilot, who in 1933 was the first aviator to fly over the falls. ![]()
