Google Earth compiles images from various sources, from satellites in geosynchronous orbit that snap low-resolution photos from tens of thousands of miles above Earth, to satellites closer to Earth that capture higher-resolution shots, and even aerial photos taken from airplanes, kites, drones and even balloons. The imagery is available to anyone who downloads the software, and archaeologists have taken advantage of this rich resource.

From a boneyard of military planes, to a polka-dot pattern created by ants, to mysterious structures etched into the Gobi Desert and even a phantom island in the South Pacific, Google Earth brings some wacky places to light. Here’s a look at some of the strangest.
