Arctic Circle
The Arctic Circle is a parallel or line of latitude at approximately 66°33’ N that marks the border of the Arctic, the northernmost region of Earth. The geographic point at the centre of Arctic Circle is the North Pole. In Canada, communities located close to this cartographic boundary include Old Crow in the Yukon, Fort McPherson in the Northwest Territories, and Repulse Bay and Qikiqtarjuaq in Nunavut. The latitude of the Arctic Circle shifts slightly depending on the tilt of the Earth’s rotational axis.
