The depth of Pakasaivo is approximately 60 meters. It has never been thoroughly studied. So far, publications of Peter Johansson are the only papers published about Pakasaivo and its characteristics. The papers focus mostly on explaining the possible ways of the formation to explain this anomalia. Concrete material (samples, measurements, photographs, videos, etc.) taken from the area are scarce. Rumours have been spreading about diving attempts, but none of these have ever been made public. This is understandable since it would require written permission.
Diving is made hard, if not impossible, by the fact that approximately in the depth of five to ten meters, the sulfur content of the water highly increases. This is caused by meromictia, a state in a lake where the usual mixing of water layers is missing. It produces oxygen-free, highly sulfurous environment, which prevents the material sunken to the lake from decaying. It is likely that divers will get strong allergic reactions from the sulfur. Depth in itself is not a problem for experienced divers since scuba divers often dive much deeper.
The steep walls surrounding Pakasaivo are dangerous, mostly consisting of fragile rocks, which crumble underfoot. The possibility of accidents is obvious, and great care must be taken when moving around Pakasaivo. I fell once, but by God's grace, I was uninjured. Please be very careful when walking in the vicinity of Pakasaivo, some rocks and formations are more fragile than what they seem
One of the most obvious dangers in Pakasaivo vicinity is that, since it is protected wilderness, is the absence of arborists. Trees
fall whereever they happen to fall. They are not marked and cut in advance to protect people. Whoever entes Pakasaivo vicinity, must
look for oneself. Take a look at these images:
So be careful and remember that you move in Pakasaivo vicinity at your own risk. In bad weather it is better not to move at all, if not necessary.
Also obvious is that the talus cones in the Pakasaivo vicinity are very hard to walk on since the rocks move under the walkers feet. In these areas, the only way to move safely is slowly and step-by-step.
Pakasaivo area has a very high population of vipers. They can sojourn anywhere and look like wooden sticks when they don't move. Always carry a snake-bite-kit with you, though most sources now claim they could worsen the situation and should not be used at all. The cellphone network is weak in Pakasaivo vicinity, but there are hot spots (or at least one bar spots) here and there, and a call to 112 should be immediately made.
The presence of snakes is understandable since Pakasaivo vicinity is has a high frog population. When walking the paths that surround Pakasaivo, one can constantly hear frogs jumping in the green thickets. It is a warm and moist environment (in the summer). Reindeers often walk from the southern end through the northern end so encounters with them can be expected. In winter time Pakasaivo is not accessible with a car, a snowmobile must be used instead. The more sporty option is skiing.
Many see Pakasaivo as a scary, hideous place, but I beg to differ. I think its one of the most beautiful God's creations in Finland. The walls, rising to altitude of 30-40 meters above the lake surface, are radiating the peace and majestity of almighty God. Waking up to the gurgle of the two streams that run into the lake is a wonderful experience that cannot be experienced anywhere else. The surface of the lake works like a mirror, both in a figurative and a concretic sense. It's almost like a mirror to one's soul, and since the rock walls are protecting the lake from winds on all sides, the still, clear surface of the lake mirrors the sky over it perfectly.
I admit that the stories told can have an effect how man interprets what he sees. When I saw this on the morning, I stopped for a moment:
There is a strong expression in the vicinity of Pakasaivo that "you are being watched." So the legends told do have an impact.
Pakasaivo vicinity used to have a hut and a souvenir shop of some sort, but these were dismantled in 2016. There still is a designated fire making place, a firewood shed, and an outhouse. There used to be multiple wooden walking platforms surrounding Pakasaivo in south and in the east, but now the walking platform in the east has been dismantled due to poor condition, and only the walking platform of the south remains. I do not much wonder that the walking platforms are being neglected and dismantled when time renders them unusable, they offer a very limited view to Pakasaivo and for many, it is not satisfactory.
The essence of the local soil is that it cracks and moves towards the lake. The person moving in Pakasaivo vicinity is being pulled towards the deep core, from which there is no return. It's understandable that walking platforms have been installed, but it's equally understandable that people choose their own paths to satisfy their curiosity. Just by walking there, the stony structures fall apart. Boots with adequate protection are strongly recommended.
Risks are obvious, and there are plenty of them, but they are worth taking.
