The paper discusses the use of aerial photography for studying relict tundra ground formations in Scandinavia. Based on photo interpretation and field verification, numerous polygonal structures – interpreted as former ice-wedge polygons and frost-induced forms – were identified. Examples from northern Norway, southern Sweden and western Denmark show how these features vary with vegetation cover, landform type and agricultural activity. The author emphasises the importance of aerial photographs for mapping, reconstructing and understanding the extent and nature of Pleistocene tundra ground, as well as for planning detailed field investigations.
