Which is the most northerly point of land on Earth?

Oodaaq lies at 83° 40′ North and 30° 40′ West, only 705 km (438 mi) south of the North Pole and 1,360 m (4,460 ft) north of Kaffeklubben Island, lying near the northeast tip of Greenland. When discovered it measured a mere 15 by 8 m (49 by 26 ft). It was discovered in 1978 when a Danish survey team led by Uffe Petersen landed a helicopter on Kaffeklubben Island to confirm that it did indeed lie further north than the tip of Greenland. Having confirmed the fact, a member of the team spotted a dark spot 1,300 m (4,300 ft) northeast of Kaffeklubben Island. The survey team landed on the island in a helicopter and later named it Oodaaq after the Inuk who accompanied Robert Peary on his journey to the North Pole.

Oodaaq or Oodap Qeqertaa is a bank of gravel and silt northeast of Greenland that may have been created by the impact of an iceberg in a shallow sea. However, the area of ice in which it appears does not move from year to year. If it was created by an iceberg, then it must have happened long ago.
