Awesome.

Pity it wasn't over Barbra Streisand's house.

On the same source image, the Great Lakes have a curiously round contour, especially Lake Michigan and Lake Huron. Maybe Michigan is another impact site.

Man I hope the next one just hit me on top of the head. I don't want to see it on the news and then 20 minutes later get hit by a tidal wave.

[Damocles]

Wow! Is that an actual pic of the site.

Can't imagine the devestation an impact of that magnitude could unleash...

[martin_fierro]

Man, that HAD to hurt.

Is a Large Asteroid Headed for Impact With Earth in 2880?

I'll worry about that in 2879.

I notice the NASA site has only 200 Megabyte images -- hardly useful, and that take 45 minutes to download on a cable modem. Why can't they have grid cut them up into useful size images?

[Dog Gone]

I don't know. I went to the NASA site, too, and decided I didn't want an image that big. I'm sure some universities do, and it probably represents the best image, but sheesh, it's not very useful to the public.

The one which is entirely too round for comfort is Hudson Bay. BIG and round. The Great Lakes + the other two huge ones to the northwest in Canada could've been caused by fragments of the big one at Hudson. After all, magnetic north on a compass is pretty close to there as well.

[Bob J]

Could this be the reason for the difference in magnetic and true north?

Also a good explanation for the high concentration of iron ores in that area.

I remember many years ago Time Magazine gave the world the definitive answer. In fact, it was their cover story. Their article stated that it was the dinosaurs’ flatulence that did them and everybody else in. No joke.

I just finished downloading all 203 megabytes of the colored map. Nice detail -- just not every image display program can load it. InfraView32 did handle it -- but still thrashed the virtual memory and took a couple minutes to load up -- even though the file is on local disk.

I'd like to see such an image ot South Africa if anyone knows of one ...

From what I've read, the impact up by Hudson Bay (very very long ago) was so large that the top of the asteroid was still outside of the atmosphere while the bottom was sriking the ground.

That is a picture of the "alleged" impact site.
