In a bay on the Potomac River south of Washington, a fleet of abandoned ships decays under water. The ships are mostly made of wood and were hastily constructed beginning in 1917, intended to be part of the war effort. Several problems prohibited the ships from ever crossing the Atlantic, and salvage rights were eventually sold. Most of the ships ended up in Mallows Bay. Google/DigitalGlobe/GeoEye

Crop circles have been around since at least the 17th century, and satellite images make them easy to see and share. They have been attributed to everything from geological pheonomena to extraterrestrials, but this crop circle promoting Mozilla's Firefox web browser was probably man-made. Google/DigitalGlobe/GeoEye
