The North Pole. The northernmost point on the earth's surface is called the North Pole. Also known as the Geographic North Pole, or Terrestrial North Pole, it is diametrically opposite the South Pole. Located approximately 442 miles north of Alert, Ellesmere Island, Canada, it's positioned at (and defines) 90Â° north latitude, so from here, all travel in any direction would be south. Under widely accepted international law, no country owns the North Pole or the region of the Arctic Ocean surrounding it.
