We encountered this stoat while searching for the northern limits of terrestrial plant life in July of 2023. It was living in a small rock cairn near the northern edge of Inuit Qeqertaat (Kaffeklubben Island) which was connected to the mainland by about 1.6km of sea ice.
NOTE ON MAP: iNaturalist and Google do not have accurate maps of the north coast of Greenland. The GPS location of this sighting is precise. I have also uploaded a screenshot of a drone map of the island showing where this location actually is (it's not in the ocean!)
