In reply to Badpanda:
A big thank you to everyone. Sounds reasonably reassuring.
I had seen the forecast and was wondering what the ground conditions (and the not-falling-through-the-ice-wearing-a-heavy-backpack conditions) were like. Good to hear that there was snow nearby. I've been watching the snow carefully and it has improved. Don't want to trash the skis (well any more than they are already)
The lakes - well, there's a lot on the Hardangervidda, esp on the Geilo/Finse stretch. Looks like the Gjende lake (in the Jotenheim) now has iced up at least in part, so that's good news. The online maps don't seem to show depths of lakes, alas.
Any more info very very gratefully received of course.
Best, BP
