The cave has long been used by the native Jivaro Indians who descend into the cave each spring using vine ladders and bamboo torches to collect fledgeling tayos (the nocturnal Steatornis caripensis). Written references to the cave go back as far as 1860 and it is known to have been visited by gold-seekers and military personnel in the 1960s.

The Gold of the Gods

’s 1973 book The Gold of the Gods, in which he wrote that Juan Moricz had claimed to have explored Cueva de los Tayos in 1969 and discovered mounds of gold, unusual sculptures and a metallic library. These items were said to be located within artificial tunnels that had been created by a lost civilization with help from extraterrestrial beings. Von Däniken had previously stirred public imagination by suggesting that extraterrestrials were involved in ancient civilizations in his popular book Chariots of the Gods?.

The 1976 Expedition

As a result of the claims published in von Däniken’s book, an investigation of Cueva de los Tayos was organized by Stan Hall from Britain in 1976. One of the largest and most expensive cave explorations ever undertaken, the expedition included over a hundred people, including experts in a variety of fields, British and Ecuadorian military personnel, a film crew, and former astronaut Neil Armstrong

. The team also included eight experienced British cavers who thoroughly explored the cave and conducted an accurate survey to produce a detailed map of the cave. There was no evidence of Von Däniken’s more exotic claims, although some physical features of the cave did approximate his descriptions and some items of zoological, botanical and archaeological interest were found.
