stone ring
Quick Summary
A stone ring, also known as a stone net or stone polygon, is a geological formation characterized by a polygonal pattern of rock fragments and soil. This pattern arises from a process called congeliturbation or solifluction, which involves the movement and sorting of materials by frost action or the flow of water-saturated soil. Typically, finer materials accumulate in the center of these polygons, while coarser fragments form the borders. A voussoir, a wedge-shaped stone used in arches and vaults, can also be referred to as a ring stone when it is visible on the face of a wall.12

On steeper slopes, stone rings and stone nets are often stretched into stone stripes by slow downhill motion of the soggy active layer of the permafrost. In other areas, patterned ground is formed…

The features require a rigorous climate with some fine-grained sediments and soil moisture, but they do not necessarily need underlying permafrost. Permafrost, however, forms an impermeable substratum that keeps the soil moisture available for frost action.…
