1:17Now PlayingIn Venezuela’s northwestern Andes, scientists found fired glaciofluvial beds—sediments scorched in a way that matches experimentally heated quartz and feldspar.
These layers may be linked to the “black mat” event of 12,900 years ago, when a comet airburst over the Laurentide Ice Sheet could have spread ejecta across North America and Europe—an inter-hemispheric catastrophe.
