(4,909 posts)Big hole in the ground. I wondered what the local natives thought about it all those thousands of years ago.
The ones that weren't killed by it.

(118,295 posts)I was impressed by the fact that, despite the big hole in the ground, no really large fragments had ever been found; the biggest was downright disappointing
The official grownup explanation was that the actual meteor hadn't been all that big (maybe 150 feet in diameter) and it mostly vaporized on contact. I could believe "mostly vaporized on contact" because everybody said they'd looked for fragments and hadn't found much -- though the small meteor size guess compared to the big crater surprised me

(193 posts)The new analysis, announced today, explains why there's a lot less melted rock in the crater than expected. The mystery has dogged researchers for years.
The big hole in the ground -- 570 feet deep and 4,100 feet (1.25 kilometers) across -- was blown into existence 50,000 years ago by an asteroid roughly 130 feet (40 meters) wide.
Previous calculations had the rock slamming into the ground at no less than 34,000 mph (15 km/sec), based in part on the expected speeds of large meteors in relation to Earth. Such an impact ought to have generated more melted rock in and around the crater than what's been found.
