Crop circles are usually associated with aliens, but this crop circle is of the geek-next-door variety. Carved into a field in Oregon, it was created by Firefox folks, Oregon State's Open Source Lab students and others, who worked through the night after doing a practice run on a nearby field.

Although the poaching of elephants is illegal, it is still a huge problem. For example, the elephant population in Chad's Zakouma National Park, one of central Africa's remaining wildlife strongholds may vanish within the next two to three years if poaching continues at recent levels. Elephant poaching is on the rise in other places as well, making this image in Google Earth all the more special. Coordinates: 10 54'13.84"N, 19 56'6.13"E

Few discoveries would be more exciting for an armchair explorer than finding the mythological sunken city of Atlantis. And plenty of folks thought just such a discovery was made when these mysterious lines were found in February. Alas, no lost city. Instead, scientists explained away the lines as ship tracks that were created from echosounding, which measures the time it takes for sound to go from the ship to the ocean floor and back.

Located in the badlands of southern Alberta, Canada, is a Native American listening to his iPod—or that's what it looks like anyway. The rock formation is the product of weather and erosion working their magic on the rocks. The "face" measures about 837 feet across and 738 feet long. The earbud "cord" is really a road that leads up to a natural gas wellhead located where the "head's" earhole would be. Coordinates: 50 00'27.35"N, 110 07'08.07"W

The gardens of the Chateau de Versailles/Palace of Versailles cover about 800 hectares of land, much of which is landscaped in the classic French Garden style.
