NASA has discovered a strange tunnel system in Greenland at a depth of 30 meters.
Upon detailed examination of the images, it turned out that the satellite managed to detect an old abandoned US military base.
"At first we didn't understand what it was at all. Later it turned out that our radar had found the remains of the "Camp of the Century". This is a military Arctic base of the United States of America, the construction of which began in the late 1950s," radiokp.ru quotes scientists as saying.
