Google Earth and the Impact Structures Database.
Most of us have heard of the Chixculub impact crater on the Yucatan peninsula in Mexico and what it probably did. Namely wipe out the entire dinosaur population some 65 million years ago. All it took was a 10 kilometer (~6 mile) piece of rock a.k.a an asteroid hitting the earth’s surface. And it left a tell-tale mark some 170km (~105.6 mile) wide.
Now that’s something you would want to see in Google Earth. Not? How about the Barringer ‘Meteor’ Crater? Or the Vredefort dome? Or the other 170 some impact craters?
The database was lifted off the ‘Earth Impact Database‘ maintained by the University of Brunswick. There you’ll find lots more information about the particular impact craters and structures.

Apart from the above mentioned resource there’s another group dealing with impact craters. The Impact Field Studies Group which has as its purpose:
The overall intent in forming IFSG is to bring together widely-separated researchers doing work at a variety of impact crater locations to share the observations and field experience for the common good of the impact community.
One of its members, David Rajmon, maintains a database which has been converted to a collection viewable in Google Earth. You can download the latest version here:
