Monday's Washington Post included a story on an asteroid that crashed into Decorah millions of years ago.

The Decorah crater if left behind, if accepted by other scientists, would be just the 184th known, according to an international database at the University of New Brunswick, the article stated.

"An asteroid as big as a city block smashed into what is now northern Iowa about 470 million years ago, says a Smithsonian geologist, supporting a theory that a giant space rock broke up and bombarded Earth just as early life began flourishing in the oceans.

The impact dug a crater nearly four miles wide that now lies beneath the town of Decorah, said Bevan French, one of the world's foremost crater hunters and an adjunct scientist at the National Museum of Natural History," the Post reported.
