Crop circles have mysteriously appeared in a Lincoln County wheat field in Eastern Washington.

The crop circles, located along Highway 174 north of the town of Wilbur, were first noticed July 24.

Nearby farmers say crop circles have appeared in Lincoln County wheat fields about once every couple of years. This particular wheat field is farmed by Greg and Cindy Geib, who say this just must be their year.

No one knows who is responsible for creating the crop circles, but the Geibs like to joke about the possibility of it being done by aliens.
