Juvfonne (61°40ʹN, 8°21ʹE) is a small, ice patch situated in the Jotunheimen mountain massif in central southern Norway (Fig. 7-1). Mass balance measurements began in May 2010. The measurements on Juvfonne are a contribution to ‘Mimisbrunnr/ Klimapark 2469’ – a nature park and outdoor discovery centre in the alpine region around Galdhøpiggen, the highest mountain peak in Norway (2469 m a.s.l.). Juvfonne has an area of 0.086 km2 and altitudinal range from 1852 to 1985 m a.s.l. (map of 2019).

The observation programme of Juvfonne consists of accumulation measurements in spring, seasonal and annual balances measured in one stake position, front position and survey of the ice patch extent.
