Approximately 36% of Finnmark lies on the Finnmarksvidda.
Geography
Finnmarksvidda near Alta. Altaelva valley is in the background.
From Alta Municipality in the west to the Varanger Peninsula in the east it stretches for approximately 300 kilometres (190 mi), being at least that wide from north to south, extending into Finland. The southeastern part of the plateau is protected by the Anárjohka National Park. The 1,409 square kilometres (544 sq mi) park opened in 1976.[2]
Some circular lakes in Finnmarksvidda may be remnants of collapsed pingos that developed during cold periods of the last deglaciation.[3]
Kautokeino municipality is Norway's largest by area. Within its borders is the coldest village in continental Norway, Šihččajávri.
