Summary: | Abstract. The maximum glacier extent during the ‘Little Ice Age ” (mid 18th century AD) in Jotunheimen, southern Nor-way, was mapped using remote sensing techniques. Inter-pretation of existing glaciochronological studies, analysis of geomorphological maps, and own GPS-field measurements were applied for validation of the mapping. The length of glacier centrelines and other inventory data were determined using a Geographical Information System (GIS) and a Digital Elevation Model. “Little Ice Age ” maximum extent for a to-tal of 233 glaciers comprising an overall glacier area of about 290 km2 was mapped. Mean length of the centreline was cal-culated to 1.6 km. Until AD 2003, the area and length shrank by 35 % and 34%, respectively, compared with the maximum “Little Ice Age ” extent. 1 |
