From the BBC: a bit long.
The cave divers who went back for their friends (http://www.bbc.com/news/magazine-36097300)
In February 2014 two divers died at a depth of more than 100m in a huge cave system in Norway. The authorities said it was too dangerous to retrieve their bodies, but four friends of the men decided to take the risk - and seven weeks later they descended into the dark and glacial waters.
At the end of the Plurdalen valley in central Norway a 35m-wide river rises abruptly out of the ground.
If you dive into this strange pond, known as Plura, and swim underground for half a kilometre, you will emerge into a long, colourful cave.
Diving hobbyists can climb out of the water here to admire the grotto, before returning to Plura. But if you are highly trained and experienced - and an insatiably curious individual - you might continue on a course that quickly plunges much deeper, becoming narrow and difficult, through ice-cold, pitch-black water.
After negotiating this "sump" - an underground pocket of water - you will finally ascend to the cave of Steinugleflaget. And about 90m above the cave's vaulted ceiling lies your exit - a crack in the collapsed side of a hill.
