Update by Astrid, Marit's sister.
Marit and Atle are still having some troubles updating themselves, so I received an other phone call last night.
They've been stuck for 2 days, day 5-7, in the tent because of bad weather. Marit could tell me that they had been outside the tent two times each during the two days, to shovel snow to keep the tent from being buried in snow. Apparently the wind has been pretty strong, so they hadn't dared to stand up when they were outside, just crept around the tent. Finally, on day 7, they kept going, though in total 'white out'. It had been a long day Marit could tell me, and the had gained 'a few kilometers' as she said. I imagine that the snow is pretty deep... Most important, they're both good!
