A 24-kilometer crater just 14.5 million years old is rather impressive but there is actually a high (4 km) altitude terrestrial impact crater twice that size that
may be just a third of its age. If so, what must early man thought about the global winter caused by Kara-Kul:

The impact event occurred less than 5 million years ago. The Kara-Kul impact structure remained unidentified until it was discovered though studies of imagery taken from space>>
