Active rock glaciers exist in the mountains of north and east Iceland and are also found very scattered in the south and west Iceland. They are normally found below N and NE facing cirques at altitudes higher than 800m but are occasionally detected at elevation down to 600m. In the mountainous costal areas of west, north west, north and east Iceland exist numerous debris bodies fulfilling all criteria requested for relict rock glaciers. In some cases we have continuous sequence from active rock glaciers at the top, changing over to relict debris bodies at lower altitudes. Spatial distribution of these debris formations in central north Iceland has been analysed and are discussed.
