Deglaciation of Finnmark, North Norway

Abstract
Altitude relationships between shore forms and their sea levels are investigated. Raised shore lines are measured in a large number of localities. Equidistant shore-line diagrams are constructed and used for relative dating purposes. Late Glacial shore lines older than the Main line (Younger Dryas time) seem to have larger gradients than assumed in previous studies. Selected glacial landforms are mapped and interpreted. In the investigated area, the ice reached beyond the coast of Finnmark during the last Glacial maximum. Distinct end moraines mark numerous halts during the subsequent ice recession. Margins of sub-stages are traced, and local glaciers and accumulation centres are located. The Main sub-stage moraines are best developed regionally. Important aspects of deglaciation patterns and ice-directed drainage are described. Streamlined forms are analysed in relation to topography, and axes of fossil inland dunes measured.
