The question Are all Alpine winterraums just for emergency? has been tagged with winterraum. It is the first question with this tag and I was wondering whether this is a term used in English?
If it is not, winter-room would probably be better suited.
As far as I am aware we use Winterraum in English as well - we don't translate it. Probably because we don't really have anything similar here - we have bothies (which I think are like refugio) but no separate room.
So I'm fine with it being tagged winterraum.
