user: What is Angel Falls?

assistant: Angel Falls (Spanish: Salto Ángel; Pemon language: Kerepakupai Merú meaning "waterfall of the deepest place", or Parakupá Vená, meaning "the fall from the highest point") is a waterfall in Venezuela. It is the world's tallest uninterrupted waterfall, with a height of 979 metres (3,212 ft) and a plunge of 807 m (2,648 ft). The waterfall drops over the edge of the Auyán-tepui mountain in the Canaima National Park (Spanish: Parque Nacional Canaima), a UNESCO World Heritage site in the Gran Sabana region of Bolívar State. The height figure, 979 m (3,212 ft), mostly consists of the main plunge but also includes about 400 metres (1,300 ft) of sloped cascade and rapids below the drop and a 30-metre-high (100 ft) plunge downstream of the talus rapids.

The falls are along a fork of the Río Kerepacupai Merú which flows into the Churún River, a tributary of the Carrao River, itself a tributary of the Orinoco River.
