In the desert in Northern Arizona there is a large mysterious crater. Its dimensions are about four kilometers in width and more than 160 meters in depth.
It is believed that the crater appeared here as a result of the fall of the meteorite, which occurred about 50 thousand years ago. But if a meteorite of this size fell to Earth, it would have disastrous consequences for the planet.
Nothing like 50 thousand years has happened, so what is the nature and origin of this abnormal crater?
