Upernavik lies on a small island at 72° 47′ 2″ N (Nordkapp at "only" 71° 10′ 21!).
It boasts of an airport on top of the hill behind town which is just about suitable for Air Greenland's Dash 8. Upernavik has permafrost that thaws superficially in summer, making everyting muddy. 2023 was even muddier than usual because Greenland had an extremely wet/rainy summer.
