A 650 to 700-foot meteorite crashed into the earth at speeds up to 67,500 mph.

The impact 450 million years ago dislodged rocks and created a massive hole in a 4-mile area called Rock Elm about 70 miles east of Minneapolis

You could also stop by North Freedom, and see if Nancy Lieder wants to tag along!

Cool beans.
If anyone does go there to check it out be sure to take a magnet with you to check all the black rocks you find! :wink:

I just noticed something else while browsing topo maps (http://www.topozone.com/map.asp?lat=44.7271&lon=-92.2001&datum=nad83) of the area: It's just a stone's throw away from Crystal Cave (http://www.topozone.com/map.asp?z=15&n=4964615.00014651&e=559126.000000024 &datum=nad83). I've been in that area already! Just didn't know it at the time.
Double field trip? :-k

I'm way ahead of you, John. I think I'll take a week off of work after school ends and drive across the state, stopping at some of the more inetresting geologic features: Baraboo, Rib Mountain, Cave of the Mounds, Blue Rock (the site of the crater)...

"They were at ground zero, so they got the brunt of it," said William S. Cordua, of the University of Wisconsin-River Falls, and one of the paper's authors.
