There was a time when locals living around Lake Paasselkä (earlier - Paasivesi) did not turn much attention to the lights howering above this large lake. Paasselkä Devil was just a play of spirits, who should care about them?

Nowadays, when people have no logical explanation to existance of spirits and ghosts, this light phenomena is very intriguing. It is observed rather often nowadays as well.

Impact crater

Specialists had a supposition that the large, deep Paasselkä lake has been formed by meteorite. Geological investigations in 1999 proved it - this enormous depression was created by a large meteorite hitting the Earth approximately 229 million years ago, in the middle - late Triassic period.

Paasselkä lake has roughly circular form and has no islands in central part, it is unusually deep - up to 75 m. Through several channels this lake is connected with other lakes of this area, forming a part of the picturesque Greater Saimaa complex.

Light balls over the lake

Light phenomena over the Paasselkä lake have been observed for centuries (mentioned in written sources since the 18th century) but in recent years the interest was revived by a wonderful book of the enthusiast of local history Sulo Strömberg. This book, issued in 2006, contains a collection of the stories of eyewitnesses who have seen these lights.

Eyewitnesses tell that Paasselkä devil can be seen at night and looks like a ball of bright light. It is not easy to determine the size of these formations: for most part they are seen in great distance, howering above the lake. It is assumed that they reach a size of football.

For most part these balls are white, also red ones have been seen. Eyewitnesses tell that the light is very bright, much more powerful than the distant lights of car headlamps, driving along the lake.

In most cases they are seen over the lake, but there are cases when these lights have been seen also in nearby forests and marshes. For most part is seen one light, but there might be several.

Paasselkä devil can be calm, resembling a bright lantern. But these seemingly calm lights might start to move around very quickly.

Local people report that sometimes these lights behave as if they have their own will. They might follow the boats of fisherman, it has been also observed that lights evade from the beam of torch.

Thus once, in the beginning of the 20th century a group of people were returning with a boat from a wedding. They noticed the light howering above the lake and decided to approach it. As they did it, the light moved away for several hundred metres very fast and was standing calm again.

In earlier times local people considered that these are some evil spirits, there are known cases of offerings to Paasselkä devils up to the early 20th century.

Nowadays several tourist companies have included "watching of Paasselkä Devil" in their tours, as additional attraction to the usual fishing tours. From time to time tourist groups report about sightings of this phenomenon, there are taken images and videos.

Convincing explanation to this phenomenon has not been found. There are attempts to explain these lights - like the old and multiple times disproved theory about some easily ignited gases rising from the sediments of lake or some rare piezoelectric effects.

Similar light phenomena are observed in other regions of the world as well, such as the impressive Chir Batti in Gujarat, India.
