The first people in North America arrived a very, very long time ago.
It was during the ice age, when thick sheets of ice covered almost all of Canada and large animals like mammoths, camels, and giant bears roamed the land.
These early people made clothing from animal skins to keep warm and made tools and weapons from stone and animal bones. They hunted animals for food, and also gathered plant foods like roots and berries.
No one knows for sure how the first people got to North America. They may have traveled by boat along the Pacific Coast, or they may have walked down an inland path between the huge glaciers that covered Canada and parts of the United States.
