For years scientists studying the famous giant meteor crater in Arizona have been puzzled by the lack of melted rock within the crater. The crater which lies in the middle of the desert and is 3/4 of a mile across was formed about 50000 years ago. Scientist now feel they have solved the mystery. The iron meteorite which previously was thought to have been travailing at 12 miles per second, may have been much slower at only 7.5 miles. In addition, the atmospheric friction may have reduced the huge object to that of a giant cloud.

LONDON (Reuters) - It's a mystery that has puzzled scientists for years but researchers said Wednesday they have discovered why there isn't much melted rock at the famous Meteor Crater in northern Arizona.

An iron meteorite traveling up to 12 miles per second was thought to have blasted out the huge hole measuring three-quarters of a mile across in the desert.

The impact of an object at that speed should have left large volumes of melted rock at the site. But British and American scientists said the reason it didn't was because the meteorite was traveling slower than previously estimated.

Its interesting to see these mysteries solved with some good detective work. Last winter we saw the crater and its quite impressive. I have to admit I was more than pissed that I had to pay admission and the amount of crap being hawked at the site was a bit much (Don't get me started on paying 10 dollars to see "four corners" either). But if you are int he area it is a must see.
