Impact Area

Caption

An asteroid struck the East Coast of North America 35 million years ago. Ejected material from the impact site was distributed over an area of at least four million square miles. Researchers have found clear traces of the impact and dated them for the first time using the uranium-thorium-helium technique. ODP 1073 on the map refers to the ocean drilling project site where the sample material for this study was collected.
