Nonsorted polygons commonly occur in extensive patterns, most frequently on nearly horizontal surfaces (although small forms have been found on slopes up to 27?; large ones have been found on slopes as steep as 31? in polar regions). Micro- scale polygons range in size from 5 cm to about 1 m; macro-scale polygons may be more than 100 m in diameter. Where vegetation is sparse, it is generally concentrated in furrows along the borders between the polygons, emphasizing the pattern. The mineral soil can be well-sorted fines, sand, gravel, or a mixture.
