[nonsorted circle] A form of patterned ground “whose mesh is dominantly circular and has a nonsorted appearance due to the absence of a border of stones” (Washburn, 1956, p. 829); developed singly or in groups. Vegetation characteristically outlines the pattern by forming a bordering ridge. When well-developed, it has a distinctly domed central area.
