Topography

The Utsjoki region is flatter and lower in altitudes than many other parts of Lapland. Large areas of Utsjoki are less than 300 m above sea level. Many of the fell summits are under 500 m in height. In general, the topography is smooth and the fells slope gently. The summits are very flat and large, as is typical of old peneplain surfaces.

remains above the horizon from 17 May to 28 July (73 days), and the polar night from 26 November to 15 January (51 days). Utsjoki, like most of Finland, has a subarctic climate (Köppen Dfc). Being the northernmost municipality in Finland, Utsjoki's annual average temperature is below freezing. Utsjoki is also the driest place in Finland, as the average annual precipitation varies between 371 and 433 mm, depending on the topography. The driest year on record was 1986, when only 234 mm of precipitation fell at the Outakoski weather station.https://helda.helsinki.fi/bitstream/handle/10138/15734/2009nro8.pdf?sequence=1&isAllowed=y Extremely low temperatures and low precipitation result in thin snow cover throughout the winters. The wind velocity strongly increases with higher elevations, and this has a major effect on the distribution of the snow. The exposed hilltops usually have no snow cover during winter. This leads to the cooling of the ground and the development of

Permafrost

Palsas are a typical permafrost feature in northern Finland. Permafrost formation in palsas is dictated by the properties of

, but frozen peat in winter conducts heat outwards, and the winter frost can penetrate deep into the peat layers. Due to these physical properties, palsas may be formed and preserved even in a climate where the mean annual air temperature is just at the

and Utsjoki regions. After detailed studies on palsas, researchers were convinced until 1982 that "so far, permafrost has been found, and probably exists only, in mires in the cores of palsas". The permafrost core in palsas is easy to detect by digging or sounding with a steel rod, and the frozen ground necessitates modern geophysical techniques for geoelectrical soundings. They allow measurement of the thickness of frozen bedrock due to its higher specific electrical resistance. Matti Seppälä (1941-2020) was undoubtedly the foremost expert on palsas. Based on existing innovative research in Scandinavia he suggested to look for the general permafrost distribution in the mountains also in northernmost Finland. The field campaign in summer 1985 in Utsjoki was supported by the

. The results were quite surprising for most scientists in Finland. Above the timber Iine a minimum permafrost thickness of ten to fifty meters was recorded with geoelectrical soundings. It seems obvious that permafrost is widespread on fjell summits of northern Finland. The Puollamoaivi mountain (432 m high) is located some 13 km NE of the Kevo Subarctic Research Station. Close to the Skallovarri palsa mire about 290 m a. s. I., an estimated permafrost thickness of over 100 meters may be expected at an altitude of 360 m, just 30–70 m higher than the surface of the palsa mire. It is concluded therefore that all sites on the crest of Skallovarri (Puollamoaivi) show the existence of permafrost, but its thickness seems to be different. These findings were confirmed with similar results in the adjacent Peldojoki, Hietatievat, Peera sites, where permafrost exists in debris as well as in bedrock. This is also of importance in the construction business, e.g. for deep foundations for telecommunication masts.
