John Norman Collie, told a frightening story of an experience he had on the mountain 35 years previously.Ĭollie said he was climbing alone in the snow and mist and heard crunching sounds, and thought he was being followed by something large and ominous. The Big Grey Man is a mythical creature described as a Scottish Big Foot, the legend of which came to prominence in the 1920s, as reported by the BBC.Īt an annual gathering of the Cairngorm Club in Aberdeen, its honorary president, the highly respected mountaineer Prof. The Brocken specter illusion is responsible for several "supernatural" sightings on Ben Macdui, the second tallest mountain in the U.K., located in the Cairngorms National Park, Scotland.
The mountain is covered in clouds or mist for 300 days a year and is the subject of old superstitions. The term Brocken specter originates in Germany and is named after the Brocken, which is the highest peak in the Harz Mountains. "This all combines to make the rather disorienting effect of a giant shadow moving in the distance," says the weather service. The Met Office says that the shadow falls upon water droplets of varying distance, which distorts perception, making the shadow appear to move as the clouds shift. The shadow will appear magnified due to an optical illusion that makes the shadow on the nearby clouds seem to be the same distance as landmarks that can be seen further away through the cloud. The illusion occurs because the sun behind the person will project the shadow through the mist. This can create the illusion that their shadow is a person seen through the mist, and it will appear to be gigantic and at a distance.

Of course you don’t have to go all the way to the highlands in order to see a Brocken spectre. The first, and so far, only time I have had to give a talk to camera like that. In which I had to given an explanation of the Brocken spectre phonon, I would like to point out that I did so off the cuff without a script. It was the photo above that led to my having a part in the a short film about The Big Grey Man of Ben MacDhui. As we got higher, we started to come out of the cloud and we began to see our shadows as Brocken spectres, much photo taking ensued.
It didn’t take long for us to enter the cloud and the loch was lost from sight. When we set off from the loch side, the cloud was low and we couldn’t see the summit, we headed up the Ptarmigan Ridge, reasoning that this would give us a good angle to the sun as we climbed. We choose Ben Lomond as a likely place to spot a Brocken spectre that Saturday. So, we hired a car, booked a B&B and headed west for the weekend. Likewise, they will see your shadow without a halo, but a halo round theirs, which just adds to the fun.Ī few years ago, Ulli and I were lucky enough to anticipate a temperature inversion in the western Highlands on a weekend. If there is someone else standing near you, unless they are very close to you, you will see their shadow without a halo and your shadow with a halo. This reflecting of diffracted light can only be seen from a narrow viewing angle, so generally you will only see the halo around your own shadow. The halo is caused by another optical illusion, a glory, where the sun is reflected by uniformly-sized water droplets in the cloud, which you are looking at, and diffracted light being reflecting back to you. It is fact your own shadow cast on to the near by clouds, the shadow seams to be magnified as you lack reference points to judge its size. A Brocken spectre or Brockengespenst, is a figure that appears out of the mist like a ghostly apparition, often with glowing halo-like rings around it head. Just in cast you are wondering what a Brocken spectre is I will give a quick explanation. These are idea conditions for seeing a Brocken spectre! Unfortunately, I have things to do in Edinburgh and can’t just rush off to go Brocken spectre hunting. They reported that it was -1° C in Aviemore and 12° C at the weather station on the summit of Cairngorm, with a layer of cloud trapped in between. Oh to being the highlands now that a temperature inversion has come! I woke this morning to hear the weather forecast talking about a temperature inversion in Aviemore.
