| Comment |
Nonsorted circles characteristically have margins of vegetation; they occur singly or in groups; their diameter is commonly between 0.5 and 3.0 m. Their central areas tend to be slightly dome-shaped and may be cracked into small nonsorted polygons. In places, the long axes of stones and sand particles tend toward vertical. The term covers both mud circles, developed in fine-grained materials, and stony earth circles, developed in gravelly materials.
