I first read this article on Yahoo’s site this morning about a 10,000-year-old meteorite whose discovery will be talked about by anthropologists, scientists, and astronomers.  The technology located the meteorite 4 feet under heavy soils of a Kansas wheat field, made an accurate 3-D representation of it, and most importantly, validates a technique targeted for investigating the terrain on Mars.  GPR (sonar) systems used in Antartica to locate meteorites are capable of penetraing the ice but aren’t as useful in dense soil and rocky areas.  What’s fascinating about this meteorite’s Pleistocene epoch date of 10,000 years ago is that the early North Americans that crossed the land bridge from Siberia into Alaska then into the Plains inhabited the land at that point and could have been witness to this meteor shower.  The article mentions that the remnants of other meteorites across the plains and into the Indian Mounds of Ohio apparently were traded as "pieces of jewelry and ceremonial artifacts."
