Ragnarbreen is a small glacier located in the central part of Spitsbergen Island. Glacier recession and landforms' development in the foreland of Ragnarbreen are quantified using time-series orthophotos and digital elevation models, which were
Controlled, ice-cored moraines: sediments and geomorphology. An example from Ragnarbreen, Svalbard
End moraine of the Ragnarbreen consists of 3 subzones: (1) outer moraine ridge, (2) culmination moraine ridge and (3) inner moraine plateau. Reworking processes were and still are the main factor influencing the morphology and sediment distribution
complex of the Ragnarbreen revealed patterns in the morphology such as the lineation of hillocks and depressions, parallel to the edge of the moraine complex.
