Antarctic Circle

In the south, a clump of ice-bound land, well within the Antarctic Circle, surrounds the pole.

I had crossed the antarctic circle; I had been borne onward for an immense distance.

On the 26th we crossed the Antarctic Circle, and the same day the temperature both of air and water rose above 32 F.

Weddell now made for the south, crossed the Antarctic Circle in W. long.

On the 15th the Antarctic Circle was crossed on a south-westerly course.
