A Spanish man read the news of the huge 31km impact crater that was found in Egypt last week and decided to use Google Earth to try to find meteorite impact spots. He was able to find a couple:
Suddenly the questions came to me. No one saw this before? How can a 31 km diameter structure not be noticed? So I decided to explore around for a while to check for similar structures.
Just passed the Libyan border entering Chad at 121 miles "flying" high when another circular structure appeared in my screen. A closer look was showing, apparently, a typical impact structure, not volcanic. Of course, finding an impact crater has no merit if it is an already known one, so I had to check and visited the Canadian Brunswick University impact crater database, in Canada, and none of the listed matched my discovery.
