Enborne crop circle

From Google Maps.

"A SHARP-eyed Newbury resident spotted this strange formation off the Enborne Road in Newbury while studying computer satellite images. Construction manager Rob Fox, of St John’s Road, was looking for an alternative route to work using on-line aerial maps when he spotted what appeared to be a crop circle outline in ploughed earth."
