Ground patterning

Recent research by Colin Baker, Daryl Garton and Ian Ross (Mercian Geologist volume 20, part 2 November 2021 pages 102-119) has uncovered extensive ground patterning of a tundral landscape in the East Midlands formed during previous ice ages including the Devensian. 

Colin's latest research has uncovered a pingo-like structures near Retford. Now published as Baker, C., Garton, D. & Ross, I. N. (2024) Periglacial ramparted depressions (presumed ground ice features) in Nottinghamshire, UK. Mercian Geologist vol 21 part 1 pp. 16 to 30.

Cadeby patterning is an example from the last ice age, Marine Isotope Stage 2 (MIS), i.e. formed ~27  thousand years ago at the Last Glacial Maximum. Gotham Moor A illustrates the cryoturbation, the mixing of soils by the freezing and thawing of ground ice, associated with the polygonal patterning (Charsley et al 1990).
