“What we had at Topper and nowhere else were pieces of manufacturing debris from stone tool making by the Clovis people. Topper was an active and ancient quarry at the time,” Dr LeCompte said. “Al Goodyear was instrumental in our approach to getting samples at Topper.”

Dr Goodyear showed Dr LeCompte where the Clovis level was in order to accurately guide his sampling of sediments for the Younger Dryas Boundary layer. He advised him to sample around Clovis artifacts and then to carefully lift them to test the sediment directly underneath.

“If debris was raining down from the atmosphere, the artifacts should have acted as a shield preventing spherules from accumulating in the layer underneath. It turns out it really worked!” Dr Goodyear said. “There were up to 30 times more spherules at and just above the Clovis surface than beneath the artifacts.”

Dr LeCompte said the finding is “critical and what makes the paper and study so exciting. The other sites didn’t have artifacts because they weren’t tool-making quarries like Topper.”

“While the comet hypothesis and its possible impact on Clovis people isn’t resolved,” Dr Goodyear said. “This independent study lends greater credibility to the claim that a major impact event happened at the Younger Dryas Boundary 12,900 years ago.”

“The so-called extra-terrestrial impact hypothesis adds to the mystery of what happened at the YDB with its sudden and unexplained reversion to an ice age climate, the rapid and seemingly simultaneous loss of many Pleistocene animals, such as mammoths and mastodons, as well as the demise of what archaeologists call the Clovis culture,” Dr Goodyear said. “There’s always more to learn about the past, and Topper continues to function as a portal to these fascinating mysteries.”

This power came forth out of the Atlantic Ocean. But afterwards there occurred violent earthquakes and floods; and in a single day and night of misfortune all your warlike men in a body sank into the earth, and the island of Atlantis in like manner disappeared in the depths of the sea.
