CASTLE Hill has been visited by aliens – or practical jokers.
A crop circle has appeared in a field below the Huddersfield landmark this week.
The circle is clearly visible in the fields below Lumb Lane, which runs across the bottom of the landmark hill.
For some people, the mysterious patterns are evidence that aliens have visited.
But to many others, the presence of crop circles merely demonstrates that someone has too much time on their hands.
But Slaithwaite woman Lynda Haigh, who spotted a possible crop circle several days ago near Hartshead, has a third theory about the Castle Hill crop circle.
Mrs Haigh, who is training to be a priestess, believes crop circles are caused by ley lines – routes between historic sites.
She said: “My understanding is that crop circles are formed by energy from the Earth. Castle Hill is on a convergence of ley lines.
“The ley lines are lines of energy from the Earth, so maybe the energy around Castle Hill has woken up.
“The energy may come from the core of the Earth.”
Mrs Haigh, who lives on Tudor Street in Slaithwaite, is training to be a priestess with a group called Earthheart.
The group is organising a Lammas – a traditional harvest celebration – at Slaithwaite Community Centre on Sunday, August 8.
The event will include fire-throwing, juggling, belly-dancing, stalls and tarot reading.
Southampton men Doug Bower and Dave Chorley are believed to be the earliest crop circlers.
They first used a four-foot plank attached to a piece of rope to create the patterns in 1978
A major study of crop circles in England in 2000 concluded that 80% of them were man-made, but the other 20% remained mysterious
Some New Age believers think that crop circles are caused by the Earth’s energy, while other people claim they are formed by UFOs
In 2009 Tasmania’s attorney general Lara Giddings claimed crop circles on the Australian island were caused by wallabies running round in circles after consuming too many poppies.
