Abstract
- The article focuses on a controversial idea that suggests that a big space rock exploded on or above North America at the end of the last ice age. The new evidence comes in the form of geochemical analysis of sedimentary layers at 25 archaeological sites across North America, 9 of them Clovis. Critics about the theory is also provided.
