Dark Hollow

The editors of Gaceta OVNI mention a hotspot of Bolivian UFOs: the salt desert known as Salar de Uyuni, a vast uninhabited space between the Real Cordillera and the Western Andes. 

According to local residents, somewhere in these salt marshes there is a "dark depression", which, apparently, is the focus of intense light, and in this place you can see strange glowing bodies entering and exiting the desert.
