El Yunque: Yúcahu's mountain and UFO lore
The rainforest peak of El Yunque was a sacred height for the Taíno, linked to the good spirit Yúcahu; in the 1990s it also became a centre of Puerto Rican UFO and 'hidden base' stories.
1995 CE · 18.30, -65.79 · status: legend
The account
Folk etymology ties the name to Yuké or Yúcahu, the Taíno lord of cassava and the sea, who was said to protect the island from the storm spirit Juracán. Modern lore adds lights in the clouds, missing hikers and rumours of underground installations, often mixed with the 1995 chupacabra wave.
The sceptical view
The forest has a heavy cloud cover and radio masts on its peaks, and no documentation supports a hidden base.
