The Zone of Silence: How a Lost American Missile Built Mexico's Strangest Legend
Where Durango, Chihuahua and Coahuila meet, the Chihuahuan Desert flattens into a closed basin called the Bolson de Mapimi. No river leaves it: rain that falls here stays until it evaporates. The ground was once the floor of an arm of the ancient Tethys sea, and it still holds marine fossils and salt deposits mined to this day. The nearest town of any size is Ceballos, in Durango, about forty kilometres away across creosote scrub. In the popular imagination it carries a very specific one: la Zona del Silencio.
The name is not ancient. It appears to date from 1966, when an engineer named Harry de la Pena, surveying for the state oil company Pemex, reported that radio traffic died out over one stretch of the basin. He called it the zone of silence, the phrase reached print, and it stuck. Older claims circulate too, usually about pilots in the 1930s said to have lost contact crossing the region. Those stories have no contemporary documentation and belong to folklore rather than to the record.
