Briksdalsbreen is one of the most accessible and best known arms of the Jostedalsbreen glacier. Briksdalsbreen is located in the municipality of Stryn in Sogn og Fjordane county, Norway. The glacier lies on the north side of the Jostedalsbreen, in Briksdalen (the Briks valley) which is located at the end of the Oldedalen valley, about 25 kilometres (16 mi) south of the village of Olden. It is part of Jostedalsbreen National Park. Briksdalsbreen terminates in a small glacial lake, Briksdalsbrevatnet, which lies 346 metres (1,135 ft) above sea level.
The size of Briksdalsbreen is not only depending on temperature, but is also strongly affected by precipitation. Measurements since 1900 show small changes in the first decades, with advances in the glacier front in 1910 and 1929. In the period from 1934 to 1951 the glacier receded by 800 metres (2,600 ft), exposing the glacial lake. In the period from 1967 until 1997 the glacier expanded by 465 metres (1,526 ft) and covered the whole lake, with the glacier front ending at the lake outlet. The glacier attracted international attention in the 1990s, as it was growing at a Time when other European glaciers were in decline.
