Äkässaivo is just as breathtaking as its sibling Pakasaivo but in a different way. Where Pakasaivo is deep and resembles a well, Äkässaivo is more like a pond. The water in it is so bright, that one can see straight to the bottom. The actual depth is anyhow unknown at the moment. It's not as deep as Pakasaivo, but perhaps half of its depth. I just guess, based on how it looks for me. Because the water is so bright, fish can be seen from the surface. It is so bright that fishes can be spotted from quite far away. Just like Pakasaivo, Äkässaivo is also surrounded by rock walls, but they are not so tall or steep as in Pakasaivo. Äkässaivo also has a narrow end in the south and wide end in the north. The overall structure is surprisingly similar to Pakasaivo.
In the shore of Äkässaivo is a huge rock, that has been worshipped by Sámi people. It can be described as monumental.
The impression given by Äkässaivo vicinity is that there has been somewhat same sort of development there that has been in Pakasaivo, but for some reason, it has stopped before reaching The depth of Pakasaivo. It seems obvious, that should the natural forces have been able to continue to whirl in the deep end of Äkässaivo, then the result would have been somewhat similar to Pakasaivo. Both in Pakasaivo and Äkässaivo, there are lots of pits here and there which seem to be almost like miniature models of the actual saivos. I have come to the conclusion that the conditions have once been in favor for the forming of saivo-like structures in Lapland.
Äkässaivo is mentioned by Samuli Paulaharju in his book "Lapin muisteluksia"(1922), which contains folktales that he collected during three-summer hiking trip. Paulaharju saw the äkässaivo as appalling and claims many people are too afraid to visit it at all. None of the things he mentions in his book can be confirmed, but the book has become a classic source, wherever Pakasaivo or Äkässaivo is mentioned.
In addition to Pakasaivo and Äkässaivo, Paulaharju classifies these places as saivos(not connected to near-by water systems by rivers):
As saivo-lakes(connected to near-by water systems by rivers) he classifies:

Also, there is a "Saivo" named dry natural formation in Kolari.
