Holocene glacier activity at the southwestern part of Hardangerjøkulen, central-southern Norway : evidence from lacustrine sediments
Lacustrine sediments from Lake Isdalsvatn downstream from the southwestern margin of the plateau glacier Hardangerjøkulen, central-southern Norway, show that the lake received glacial meltwater until 7890 ± 95 BP. A thin, bluish-grey minerogenic silt layer probably reflects a short glacial (re)advan...
