I was very excited when I first read about the Viking colony on Greenland - farms, villages, churches - for want of a better word European life. All collapsed under a series of bad winters - climate change?

It seems those Sagas where passed on through an oral tradition for 200+ years before being written down - about as reliable as the Old Testament as a road map of Palestine?

Will this lead to some undiscovered Viking settlements of some scale? Seems unlikely it ever happened doesn't it?
