We has a very large meteor here in Colorado this morning, lasted a long time, passing North to South...about 0605 local MST.
Could this have been it?

NORAD is investigating this morning's event and should announce something later today.

Pieces of a Russian rocket body re-entered the Earth's atmosphere early this morning, blazing a fiery path across the skies over Colorado and Wyoming, according to the North American Aerospace Defence Command.
Initial reports indicate that a chunk of the SL-4 rocket landed in Riverton, Wyo., near Highway 28, at around 6:13 a.m., according to NORAD. No damage was reported, and the debris is not believed to be hazardous, according to a NORAD news release.

That's terrific, I actually got to see a rocket body reenter. There were flashes, and it moved relatively slowly compared to a meteor, pieces coming off and falling behind.. I figured it was likely something big coming in from LEO...then I found this thread , the orbit track map...bingo! And right in NORAD's back yard!
Very neat.

It wasn’t a meteor, it was rocket booster
A brilliant object that burned in the early morning sky was a Russian booster rocket re-entering the atmosphere over Colorado and Wyoming, according to NORAD and the U.S. Northern Command.

(Ed - of course there is a remote possibility that it may not have been rocket debris... it may still be worth looking for meteorite fragments)

Default NORAD looking for Russian rocket in Wyoming
From CNN.com
Quote:
A spent Russian booster rocket re-entered the atmosphere Thursday over Colorado and Wyoming, the North American Aerospace Defense Command said.

NORAD spokesman Sean Kelly said the agency was trying to confirm a report that a piece of the rocket may have hit the ground near Riverton, Wyoming, at about 6 a.m.

Kelly said military personnel had not yet reached the scene.
By the way Blob, I think the link you have in your last post is incorrect.

SkyFOX pilot Rob Marshall and photojournalist Josh White captured the event at about 6:15 a.m. Mountain Standard Time while they were flying over Denver.
You've read about it, now See the Video

Several viewers across the intermountain area saw a bizarre sight streaking across the dark morning sky.
Our CBS affiliate in Denver had their chopper in the air at the time and shot this great footage.

Amazing footage. It would be nice to see some of the pieces that fell back to earth.

I've got an NG magazine with a picture of an early rocket stage that feel back into the Russian tundra, with butterflies all around it. Beautiful pic. Though the parts hitting the earth here should have been smaller than that, I assume.

A low density object is slowed at higher altitude than a high density one, and experiences lower temperatures as a result, improving its chances of survival. Several complete propellant tanks from Delta rockets have survived. These are about 2 metre diameter objects.

There is a gallery called "Kazakhstan's spaceship junkyard." I recall seeing these pictures on BAUT before: ("click here to begin")

What killed the cows? Toxic propellant?

ALTAI, Russia - Dead cows lie on a cliff, 2000. Locals say that whole herds of cattle and sheep regularly die because rocket fuel poisons the soil.

pic 9 is the one I meant. Apparently, they use quite toxic fuel.

Interesting description from the chap on the video (presumably, this predates the knowledge that it was a rocket fragment):

"Pieces of an extinct constellation."

Huh.

Hum,
Yeah,
the extinct constellation would be the Quadrans Muralis, that contains the radiant of the Quandrantid meteor shower.

Apparently, they use quite toxic fuel.

Some of Russia's older boosters use hypergolic propellants like our Titan series did. Hypergolic propellants are corrosive and very toxic.
