Juvvasshøi

Juvvasshøe is a mountain in Lom Municipality in Innlandet county, Norway. The tall mountain is located in the Jotunheimen mountains just outside the border of Jotunheimen National Park. The mountain sits about southwest of the village of Fossbergom and about northeast of the village of Øvre Årdal. The mountain is surrounded by several other notable mountains including Lauvhøe to the northeast, Glittertinden to the east, Galdhøe and Galdhøpiggen to the southwest, and Storhøe to the northwest.

==Climate and permafrost== The mean annual air temperature at Juvvasshøe is . This value is extrapolated from a larger number of official Norwegian weather stations. According to the experience in other alpine and polar regions this temperature indicates that permafrost must be widespread and probably extends to a depth of several hundred meters. Within the EU-sponsored project PACE (Permafrost and Climate in Europe), a deep vertical borehole in bedrock was drilled in August 1999 on Juvvasshøe at an altitude of above sea level. The stable ground temperature at a depth of is still . The measured geothermal gradient in the drillhole of per allows a calculation of a permafrost thickness of , a proof that widespread permafrost occurrences must exist in the Jotunheimen area at these altitudes.
