The dating of the shocked quartz coincided with the rapid disappearance of the Clovis people, a technologically advanced hunter-gatherer culture that had dominated much of North America for centuries. Archaeological evidence has shown that their distinctive stone tools vanish abruptly from the record shortly after this period. This timing also marked the beginning of the Younger Dryas, a sudden and dramatic cooling event that lasted about 1,200 years.
