Talk:Patterned ground

Not the expansion of water

This article suggests that the anomalous expansion of water is the mechanism for frost heave and yet the article on frost heave starts by proving that this cannot be the case. 62.49.27.35 (talk) 14:53, 2 October 2009 (UTC)

periglacial environments only?

Yesterday I stumbled on this article from another wikilink. I was wondering if the phrase "patterned ground" has been used only to refer to periglacial environments only, or to patterns in earth generally? For example, I was thinking of Bérnard cells in endorheic lakes. I couldn't find a sample image on Wikipedia, but here's an OK one from a travel blog: https://www.travelblog.org/Photos/137707 with a direct link to the image of https://photos.travelblog.org/Photos/1449/28047/f/137707-El-Salar-de-Uyuni-0.jpg 136.62.254.174 (talk) 19:22, 29 July 2018 (UTC)

Thank you for your suggestion. If there are other mechanisms, they should be within the scope of this article. However, a pattern at the surface of a lake isn't really "ground", unless it's a dried lake bed, which seems to be depicted in your image. Cheers, HopsonRoad (talk) 10:35, 31 July 2018 (UTC)

Periglacial environments contradicts example of where patterned ground is found

The article says "It is typically found in remote regions of the Arctic, Antarctica, and the Outback in Australia," but does not provide a citation for this, and also states that it happens in periglacial regions, but according to https://en.wikipedia.org/wiki/Periglaciation it seems like Australia is not periglacial, and also I could find no sources anywhere that suggested Australia has periglacial processes and/ or patterned ground.

Update: I think the source of this may be this article: https://www.sciencenews.org/article/patterns-nowhere though I do not find it to be particularly convincing / it does not prove this. Definiteforest (talk) 21:11, 5 February 2024 (UTC)

Range of processes

I have removed this sentence since, while the source mentions 'polygons', it does not appear to be describing 'patterned ground' which is a periglacial feature involving rocks and mineral soils: In the northern reaches of the Canadian Boreal forests, when bogs reach a eutrophic climax and create a sedge mat, tamarack larch and black spruce are often the early colonists within such a polygonal climax sedge mat. Elsewhere in this article are descriptions of patterns in nature (e.g Atacama) which are not encompassed by the normal use of the technical term 'patterned ground' which is restricted to certain types of pattern produced in a particular environment per the first sentence of the lede. Stone stripe ought perhaps to also be brought within this article, though that page has its own issues. Geopersona (talk) 06:21, 31 January 2026 (UTC) Geopersona (talk) 06:21, 31 January 2026 (UTC)
