From ground level the offensive image is not especially discernible, but a bird's eye view of the lake clearly shows what the cheeky prankster - whose identity is unknown - has taken the time to create.

The image has been spotted by Google Maps users, with one person writing: ''Travelled all the way from New York to see this beauty.''

Earlier this year, eyebrows were raised in Illinois in the US, with people pointing out that a Christian Science Church had been designed in the shape of a penis.
