Archaeologists discovered that people came to the North American continent long ago possibly by crossing fifty-six miles between Asia and Alaska. While the date and details of their trip remain unknown, as nomads, they migrated during the spring and summer in search of food for their herds and camped during the winter. Eventually, they settled from the east coast to the tip of South America. Artifacts found from this era were used for hunting animals to get food and clothing.
