Small sorted nets occur on glacial tills deposited since the end of 19th century by the Fláajökull (southeast Iceland) and Elisbreen (northwest Spitsbergen) glaciers. The nets have mesh diameters of 0.1 to 1.2 m. They possess a relatively flat microrelief and depth of sorting of 5 to 15 cm. Clasts within the coarse domain (stony borders) and till fabric analysis display chaotic orientation. The nets within the Fláajökull moraine are more active compared with nets from the Elisbreen moraines. Despite major differences in climatic conditions between southeast Iceland and northwest Spitsbergen, it is inferred that there is no distinct difference in the sorted patterns that have developed upon the young moraines of the two glaciers.
