anada's last period of
glaciation originated in the north-central part of the country about
25,000 years ago. At the height of glaciation 18,000 years ago, a
thick sheet of ice covered virtually all of Atlantic Canada. Around
13,000 years ago, the ice began to recede, allowing wildlife and
vegetation to become re-established over the ensuing several
thousand years. Aboriginal peoples living south of the glaciers
soon began moving into newly ice-free areas to exploit abundant
natural resources.
The red dots on this map indicate the earliest
known archaeological evidence of human habitation in Atlantic Canada,
dated to about 11,000 years ago.
