The scant evidence available indicates that about 3,700 years ago, Norse people began to realize that they could sail into the big bay, (Hudson Bay) in large freight ships. Those ships are called "Longships." Longships pulled a small knarr and, perhaps, carried two or more knarr on deck. These knarr with crews of fifteen to sixteen mem were unloaded at the mouth of the Nelson river.
Then the knarrs would be pulled up the Nelson river to Lake Winnipeg (Stinking Bay) and then the Red River to reach Wynland of West.
Rowing up the Nelson and the Red Rivers took nearly a month. The Pope at the Vatican in 1160 knew that the knarr took twelve days to return to Hudson Bay.
