Clovis Point This spear point excavated along the Columbia River in what is now Washington state was crafted by Clovis people around 11,000 BP. It illustrates how small fragments of stone were chipped away to create the point used for killing animals—a feature common to Clovis points throughout the hemisphere. Archaeologists believe that such commonalities document a widely shared Clovis culture practiced for many generations. Washington State Historical Society.
