Casper at Thinklemon.com has released a couple of new variations on his collection of Impact Craters (aka Craters) which I wrote about earlier. He announced on Monday this week Google Earth files for the most recent impact structures and the oldest impact structures. You should read his announcement because he provides some perspective on these new variations. Or, if you are impatient, you can download the most recent craters 
, or the oldest craters now.
Very interesting Blog ! I take the freedom to give your link inside my blog as I noticed a lot of people are concerned with Google Earth.
