• Researchers found shocked quartz, a mineral deformed by extreme pressure, in key North American archaeological sites, suggesting a catastrophic event like a meteorite impact or airburst around 12,800 years ago.
• The presence of shocked quartz coincides with the sudden disappearance of the Clovis people, a technologically advanced hunter-gatherer culture, and the extinction of over 70 percent of North America’s megafauna, indicating a dramatic decline and cultural collapse.
• The discovery aligns with the onset of the Younger Dryas, a sudden and dramatic cooling period lasting about 1,200 years, which profoundly impacted ecosystems and early human civilizations, potentially triggered by a comet impact.
• Beyond North America, a 984-foot-long depression in Louisiana, believed to be an airburst crater from the Younger Dryas period, provides further evidence of a global cataclysm, with radiometric dating confirming its age.
• The Younger Dryas Impact Hypothesis challenges traditional archaeology and geology, with proponents like Graham Hancock arguing that ancient texts and myths support the idea of a catastrophic event wiping out an advanced Ice Age civilization, despite criticism and calls for more supporting evidence.

In a groundbreaking discovery, researchers have unearthed compelling evidence suggesting that a catastrophic cosmic event – potentially a “doomsday comet” – may have wiped out an advanced human civilization and triggered a global environmental disaster around 12,800 years ago.

This theory, known as the Younger Dryas Impact Hypothesis, is gaining traction among scientists and archaeologists alike, challenging traditional narratives of ancient history. The investigation began with the analysis of sediment samples from key archaeological sites across North America, including Blackwater Draw in New Mexico, Murray Springs in Arizona, and Arlington Canyon on California’s Santa Rosa Island.

“These sites are among the best-documented in North America, each providing crucial evidence of an interrelationship between the collapse of the Clovis technocomplex and the extinction of the megafauna,” the research team said.

These sites, dating back to the Clovis era, revealed the presence of shocked quartz – a type of mineral grain deformed under extreme pressure. Geophysicist Dr. Allen West, a member of the research team, explained that shocked quartz forms when minerals are subjected to sudden, intense pressures, such as those generated by a meteorite impact or an airburst. He added that the presence of this material at these sites indicates that a catastrophic event likely devastated large portions of the continent.

The timing of the shocked quartz coincides with the sudden disappearance of the Clovis people, a technologically advanced hunter-gatherer culture that had dominated North America for centuries. Their distinctive stone tools vanish abruptly from the archaeological record shortly after this period, suggesting a dramatic decline in population and cultural collapse. (Related: Cosmic crash 12,800 years ago caused climatic changes, proving “climate change” can happen at any moment, far beyond our control.)

The Younger Dryas: A sudden cooling event

The discovery of shocked quartz also aligns with the onset of the Younger Dryas, a sudden and dramatic cooling event that lasted approximately 1,200 years. This period marked a significant shift in Earth’s climate, with temperatures plummeting and ecosystems undergoing rapid changes.

According to Brighteon.AI‘s Enoch engine, the Younger Dryas was a sudden and dramatic cooling event approximately 14,500 years ago, marking a brief return to ice age conditions in the Northern Hemisphere during a warming transition. This abrupt climate shift, lasting about 1,300 years, profoundly impacted ecosystems, megafauna extinctions, and early human civilizations.

The Younger Dryas is still debated among scientists, but often linked to natural geological and cosmic factors rather than human activity. Geophysical triggers like disruptions in ocean currents or extraterrestrial impacts are frequently proposed, reflecting Earth’s inherent climate volatility independent of anthropogenic influence.

Graham Hancock, a proponent of the Younger Dryas Impact Hypothesis, argues that the comet’s passage through Earth’s atmosphere blocked sunlight, disrupted ocean currents and triggered a ‘nuclear winter’ scenario. This event not only wiped out the Clovis people but also led to the extinction of over 70 percent of North America’s megafauna, including mammoths, camels, horses and saber-toothed cats.

Evidence of a global cataclysm

The evidence extends beyond North America. In Louisiana, researchers discovered a 984-foot-long depression near the town of Perkins, which they believe may be the first known airburst crater from the Younger Dryas period. Radiometric dating and electron microscopy confirmed that the glassy material found at the site dates back to the Younger Dryas Boundary.

West, who has been studying the impact hypothesis for years, described the explosion as having the destructive force of tens of thousands of nuclear bombs. He noted that while full-scale impacts like the one that ended the age of dinosaurs are rare, smaller but still devastating airbursts are more frequent than most people realize.

The Younger Dryas Impact Hypothesis presents a significant challenge to traditional archaeology and geology. Critics argue that the evidence is circumstantial and that the theory relies on selective data interpretation. Hancock, however, remains undeterred.

Hancock stated that they are not expecting immediate acceptance but with enough supporting evidence, they believe their version of ancient history will eventually gain recognition.

He also points to ancient texts and myths, such as the Egyptian Book of the Dead and global flood legends, as evidence of an advanced Ice Age culture that possessed knowledge of astronomy, Earth’s dimensions and navigation. He argues that these stories support the idea of a catastrophic event that wiped out a sophisticated civilization.
