Microtektites were discovered in the Transantarctic Mountains. Microtektites are described by this article as "tiny beads of meteor impact glass." These microtektites are linked to an unknown crater created 800,000 years ago. The new discovery increases the debris range by 2,000 miles. Were the meteor crashed causing the melted rock to be thrown in the air and rain back down over such a wide area is unknown and may never be known because it potentially has since been covered by the ocean and covered with sediment.
