During the little ice age - remember that - 1888 iirc. We are still
coming down from it. The massive ice flows started up again and are
now
retreating. Just a long time in the process.

The Hudson bay used to be navigable with cargo ships and the little
ice age froze it over. They just found some ships that were frozen
in the pack trying to bring in goods.

History, history is our friend.

I've tried to research early exploration of the New World, such as the
location of Vinland and Prince Henry Sinclair's alleged visit to New
England 100 years before Columbus.

One thing that stands out is that the story of an ice-free Northwest
Passage appeared almost immediately after Columbus, centuries before
we had officially documented knowledge of what was up there. The area
above central Canada wasn't fully mapped until the 1850's, by rescuers
searching for the lost Franklin Expedition.
