SE tip of Tigvariak I., a W point of entrance to Mikkelsen Bay, on Beaufort Sea coast, Arctic Plain.
On Aug. 7, 1826, Franklin, Royal Navy (RN), (1828, p. 152) named the island "Lion and Reliance Reef," after his two boats. The Lion had been driven aground at this place. E. de K. Leffingwill (1919, p. 89) adopted the Eskimo name Tigvariak for the island, and, in his text, applied Franklin's names to the NE (Point Reliance) and NW (Point Lion) points of the island. His maps, however, show these points as Reliance Point and Lion Point. A sandspit has extended the island in recent years, and the application of the name "Reliance Point" now extends one mile S of Leffingwell's location.
