Jrnl. 63 208 We propose here to style the two forms ‘stone-polygons’ and ‘fissure-polygons’ respectively. The stone-polygons are represented at one extreme by isolated stone-circles, while at the other they may become drawn out into a series of elongated mud-strips, separated by strips of stone. 1950 A.

Washburn in Revue Canad. de Géogr. 4 8 The terms Rutmark, Strukturboden..stone polygons, mud circles, soil circles, mud polygons, soil polygons, fissure polygons, tundra polygons, stone stripes, soil stripes, solifluction stripes and others have all been used to describe features here collectively named patterned ground for want of a satisfactory collective term in English...
