Haitón del Guarataro

The Haitón del Guarataro is a solutional cave system in the Sierra de San Luis in Falcón State, Venezuela, 2.5 kilometres (1.6 mi) south-east of Curimagua. It is the deepest limestone cave in Venezuela, and the entrance is a tourist attraction within the Juan Crisóstomo Falcón National Park. A large entrance shaft 12 metres (39 ft) in diameter leads via drops of 168 metres (551 ft), 55 metres (180 ft), and 19 metres (62 ft) to a stream passage which eventually chokes. It has a depth of 305 metres (1,001 ft), and a total passage length of 640 metres (2,100 ft). It was first explored and surveyed in April 1973 by members of the Venezuela '73 British Karst Research Expedition. It is formed in Oligocene reefal limestone.
