About 1,100 years ago a space rock the size of a big tree stump slammed into western Canada, carving an amphitheater-like crater into the ground and littering it with meteorites, a new study found. The rock that made the newly identified crater might have created a sky show similar to the one that tore across northern Alberta's skies in the early evening hours of November 20. But unlike the recent fireball -- which broke apart as it streaked through Earth's atmosphere -- the meteorite that carved the newly announced crater would have stayed solid until impact... Meteorites, objects from space that hit Earth, often come from asteroids. Only about 175 impact craters are known worldwide, and when a space rock does slam into Earth with enough force to create a crater, the rock almost always evaporates on impact.

A 1,100-year-old crater created by a meteorite the size of a big tree trunk has been discovered underneath thick growth (top) in western Canada, a November 2008 study said. Scientists used a new crater-spotting imaging technique to "strip" away the vegetation and reveal the 120-foot (36-meter) wide circular impression (bottom).

I like quantifiable science!

I've updated the ping message templates. I've dropped Mirabilis, added National Geographic and Discover, and replaced the dead podcast links with The Archaeology Channel. Thanks again to Mike Fieschko for pointing out the problem. |

Hey, at least the processed image showing the crater has an Etch-a-Sketch quality.
Not that anybody ever does something like that, but they do!
When I read the title I thought: So that is where Rosie O'Donnell hit when they booted her out of Hollywood...
Saw a GREEN meteor one night, it was supercool...

Figured it was a little green man that bailed out early.
Is that what killed the dinosaurs? (JOKE!)
That's just silly
Everyone knows it was Bush's fault.
The crater is 36 m wide. The object required to create that crater is far smaller.
BUMP!
Are you "Den?"
...obscure Heavy Metal reference...
How do you think a description of this thing was passed down in legend and myth?
Could it be a Thunderbird?
I must be getting old if that’s an obscure reference...dang...
I’m sure the people there at that time were too busy preserving 50,000 year old folklore with minute details about ancestors to bother with a little rock impact. /sarc
No, but it made a moose have bad dreams for a couple of weeks.
