World War I
World War I (WWI or WW1), also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918.
 More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history.
 Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare.
 It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved.
 Unresolved rivalries still extant at the end of the conflict contributed to the start of the Second World War only twenty-one years later.

 It measures about 320 m. (1050 ft) by and 240 m. (790 ft.) and up to 20 m. (65 ft.) deep.
 The water level was documented at 384 m. (1258 ft) above sea level but may have diminished in recent years.

 There is no firm evidence that members of King Leopold expedition actually reached the lake.
 Lago Leopoldo was first seen from the air as a landmark near the Cerro Autana tepui during the 1950s.
 The lake was first visited by helicopter in March 1973 by the Spanish naturalist Félix Rodríguez de la Fuente.
 The following April, the terrestrial route from the original King Leopold III camp was established by a Venezuelan expedition which reached the shores of the lake on April 18, 1973.
 Lago Leopoldo figures prominently in the oral history and lore of the native Piaroans where it is referred as “Paraka-Wachoe” or the lake in the mountains.
 Lago Leopoldo now renamed Lago Autana has been included as a natural monument within a protected area which includes the Cerro Autana and adjacent lands. Konstantin Vakulovsky
