In "Hiawatha the Unifier", the group of dissatisfied people crossed the Mississipi by laying a long grapevine tree to cross the river.
Explanation:
In the legend about Tarenyawagon the upholder of the heavens, we learn of a time when he looked down from the heavens and saw the suffering of the people. He changed his form to that of a man and came down to help these people. He led them along unknown routes to a place where he built a longhouse that housed them all.
After some years, he assigned the people to different locations but some groups of people who were unsatisfied with their assigned locations decided to cross the Mississipi together. They used a wild and long grapevine tree that ran between the two banks of the river to cross the river. After they crossed, the tree broke and that divided the East from the West.
