Axel Heiberg Island

Axel Heiberg Island is a large, uninhabited island in the Canadian Arctic Archipelago, administered as part of Nunavut. It is notable for extensive glaciation, remote polar landscapes and exceptionally well-preserved Eocene fossil deposits.

The island’s interior is dominated by ice caps and valley glaciers, while coastal fiords and rocky shores characterize much of the shoreline. Scientific research stations operate intermittently on the island to study geology, paleobotany and glaciology, and visits are primarily by research teams and specialized expeditions.

Axel Heiberg has yielded important paleontological finds - notably fossilized forests and plant material preserved in permafrost that date to the Eocene epoch and inform studies of past Arctic climates. There are no permanent civilian settlements.

Geographically the island lies in the High Arctic west of Ellesmere Island and north of mainland Nunavut, within Canada’s northern Arctic archipelago.

• Administration and use: The island is uninhabited and administered as part of Nunavut; it is primarily visited by scientific teams studying Arctic geology, glaciology and paleontology.
• Fossil forests: Axel Heiberg Island preserves exceptionally well-preserved Eocene fossil forests and plant remains that have provided important information on polar climates about 45 million years ago.

What to See #

• Expedition Fiord and research station: Expedition Fiord area, site of preserved Eocene fossil forests and the location of a small research station used by scientific teams.
• Glaciated interior and ice cap: Large, glacier-covered interior with valley glaciers and an ice cap that dominate the island's highlands and feed coastal glaciers and moraines.
