Why It Happens Here and Nowhere Else
There is nothing unusual about the lightning itself. What is unusual is the reliability with which the storms that produce it rebuild over the same patch of marsh. Lake Maracaibo sits in a basin closed on three sides by mountains, the Sierra de Perijá to the west and the Cordillera de Mérida to the south and east, open only northward to the Gulf of Venezuela. Through the day the lake and its swamps load the air above them with heat and moisture. After dark a nocturnal low-level jet accelerates down off the ranges, cool mountain air meets warm lake air, and the collision forces the whole column upward into towering storm cloud. The convergence happens at the same place because the topography does not move. Earlier theories credited uranium in the bedrock, then methane seeping from the swamps and the oilfields beneath them. The methane explanation is largely discounted now, mostly because it predicts peak activity in the dry season and the observed peak is the opposite.
The Lighthouse of Maracaibo
For as long as there have been ships on this coast the lightning has functioned as a navigational fix, visible at very great distances and always in the same quarter of the sky. Spanish sailors called it the Faro de Maracaibo, the lighthouse of Maracaibo, and the Lanterns of Saint Anthony. Humboldt described it in 1826. The Italian geographer Agustín Codazzi, writing in 1841, made the lighthouse comparison explicitly. It is credited with helping Admiral José Prudencio Padilla's republican fleet at the Battle of Lake Maracaibo on 24 July 1823, the engagement that ended the Venezuelan war of independence. A frequently repeated story has Lope de Vega describing the lightning in La Dragontea in connection with Francis Drake's 1595 raid, though scholars reading the passage think the glow he describes was more likely burning ships. The white ray on the flag of Zulia is the lightning, and the phenomenon was declared a natural heritage site of the state in 2005.
The Villages on Stilts
The lightning is watched from palafitos, stilt houses built out over the water in a tradition that predates the Spanish arrival by a long way. Houses here can be floated to a new position on a pair of boats, and periodically are. The village most associated with the phenomenon is Congo Mirador, which held over a thousand people at the turn of the century and is now close to empty. The Catatumbo River, its course altered upstream for irrigation, has been filling the lagoon with sediment for years, and by the early 2020s only a handful of families remained; the rest moved to Ologá, ten minutes away by boat, or to Puerto Concha on the mainland. The village's disappearance is the subject of Anabel Rodríguez Ríos's documentary Once Upon a Time in Venezuela, which premiered at Sundance in 2020 and was Venezuela's submission to the Academy Awards the following year. Ologá is now the practical base for anyone watching the storms.
A Lake in Serious Trouble
Lake Maracaibo is around thirty-six million years old and sits on top of some of the largest oil reserves in the world, which has not been good for it. Thousands of kilometres of ageing underwater pipeline, much of it poorly mapped, run beneath a lake whose operator has been in financial and technical collapse for a decade. Oil slicks and vast blooms of algae and duckweed, fed by crude, sewage and farm runoff, are large enough to be photographed from orbit; NASA published Landsat imagery of them in September 2021. Venezuelan monitoring groups counted 86 spills in 2022 alone, one of them stretching fifteen kilometres. The fishing communities that built the stilt villages describe catches coming up coated in oil. Any honest account of this place has to carry that alongside the spectacle, because the two are in the same frame.
