In the central part of the Mapimí Bag, there is an area called Zona do Silêncio. The enigmatic name is worthy of endless myths that have sprung up around the area. El Bolsón de Mapimí is located in the north-central part of the country, about 180 km northwest of La Laguna, whose main cities are Torreón-Gómez Palacio-Lerdo, which is part of the Chihuahuan Desert.

The Zone of Silence is located between Durango, Chihuahua and Coahuila, between parallels 26 and 28, in the place called Trino's vertex. It is called the Silence Zone because radio waves cannot be transmitted normally and this only occurs in some small areas because there are magnetic fields.

From time to time this large area of ​​land was under the waters of the so-called Thetis Sea, which is demonstrated by the existence of marine fossils in the area.

Also in the Silence Zone, there are areas with a high concentration of aerolyte fragments, as well as endemic species such as the desert tortoise, unique reptiles in the world and the abundance of violet nopales that owe their color to the layers that protect us from the rays. solar lights were eroded by the solar wind.

The Zone of Silence is often compared to the Bermuda Triangle, with the Pyramids of Egypt, the Sacred Cities of Tibet, Cape Canaveral, all located between parallels 26 and 28 (Hunt 1984).
