The dramatic pictures were taken in north west Greenland by British Arctic photographers Bryan and Cherry Alexander and show a storm brewing over an Inuit community.
The award-winning photographic pair were staying in Qaanaaq, about 800 miles from the North Pole, when the apocalyptic cloud colouring began over Inglefield Bay.
'It was just before dawn, around 10am, when an Inuit friend of mine whose house I was staying in came to my room and suggested that I take a look at the sky,' Mr Cherry said.
'I went outside and was stunned by the beautiful and dramatic cloud formation. I just couldn't believe my eyes. I have worked in the Arctic regularly for the past 37 years and I had never seen the sky like it.'
The pictures show a thin layer of medium-level cloud that has been pummeled by winds churned up between the glaciers below.
'You often see clouds repeating the shape of the ground below,' a spokeswoman from the Met Office said.
'The wind comes in from one side, is lifted up over the mountains and hits the clouds before coming down again. It's a dramatic example of what is known as an orographic effect.'
The angle of the rising sun helped to highlight the different colours and intricate patterns.
'It looked apocalyptic and like a scene from one of the Lord of the Rings movies,' Mr Cherry said.
'Because of the northern winter, the sun rises later and later the nearer you are to the North Pole. That's why even though the pictures were taken at dawn, it was actually ten in the morning.'
For Mr Cherry, it was a once-in-a-lifetime photographic event.
He said: 'I grabbed my cameras and photographed for about an hour as the cloud formation changed and the colour of the clouds turned from grey to pink as the rising sun's rays caught them.
'An hour or so later the drama was gone and it became just another cloudy autumn day in North Greenland.'
But it was not just the Alexanders who were blown away by the natural wonder unfolding in front of them.
Mr Cherry said: 'Just about everybody in the village was amazed, including an elderly Inuit hunter who told me that he had never seen anything like that before in his life.'
The Alexanders have travelled to the region almost every year since the early 1970s, exploring it extensively to document the life of the North's native peoples.
However, in all that time they said they had never seen anything close to the incredible skies they witnessed this autumn.
