Patterned Ground

Patterned ground is the distinct, and often symmetrical geometric shapes formed by ground material in periglacial regions. Typically found in remote regions of the Arctic, Antarctica, and the Australian outback, but also found anywhere that freezing and thawing of soil alternate, the geometric shapes and patterns associated with patterned ground are often mistaken as artistic human creations. The nature of patterned ground had long puzzled scientists but the introduction of computer-generated geological models in the past 20 years has allowed scientists to relate the formation of these features to phenomena associated with frost heaving, which refers to expansion that occurs when wet, fine-grained, and porous soils freeze.
