The Cromerian interglacial is a name for an interglacial period which occurred between 600,000 and 450,000 years ago. The name is used by British geologists and archaeologists who named it after the site of West Runton near Cromer in the English county of Norfolk where deposits it created were first found. Glaciation, often called an ice age, is a geological phenomenon in which massive ice sheets form in the Arctic and Antarctic and advance toward the equator. ... The Geologist by Carl Spitzweg A geologist is a contributor to the science of geology, studying the physical structure and processes of the Earth and planets of the solar system (see planetary geology). ... Archaeology or sometimes in American English archeology (from the Greek words αρχαίος = ancient and λόγος = word/speech) is the study of human cultures through the recovery, documentation and analysis of material remains, including architecture, artefacts, biofacts, human remains, and landscapes. ... WEST RUNTON from Incleborough Hill) West Runton is a Village in North Norfolk approximately ¼ of a mile from the sea. ... Cromer is a seaside town and civil parish on the north coast of the English county of Norfolk. ... Norfolk (IPA: //) is a low-lying county in East Anglia in the east of southern England. ...
It is a Pleistocene stage of the Quaternary period and is analogous to the Aftonian interglacial in North America and the Günz-Mindel interglacial in the Alps. It was a period of warm climate and its deposits lie beneath those from the following Anglian glaciation and above those from the preceding Beestonian glaciation. The Pleistocene epoch (IPA: ) on the geologic timescale is the period from 1,808,000 to 11,550 years BP. The Pleistocene epoch had been intended to cover the worlds recent period of repeated glaciations. ... This article is about the geologic period. ...

The Beestonian stage is the name for an early Pleistocene glacial stage used in the British Isles. ...
Passing from the question of glacial to that of interglacial climate, we are confronted with an embarrassing confusion as to the number, character and correlation of these interglacial stages.
Of the Aftonian interval Thwaites remarks, "strangely enough, although the evidence on which the Aftonian was originally defined is worthless there is, nevertheless, a real 'Aftonian' interval of great length and possibly constituting a genuine interglacial stage" (45).
A similar analysis of the last interglacial agrees in its general import but differs in detail, presenting a predominantly cool and moderately humid character.
In addition to the stratified deposits and their contents, important evidence in favour of interglacial epochs occurs in the presence of weathered surfaces on the top of older boulder clays, which are themselves covered by younger glacial deposits.
The cause of the interglacial hypothesis has been most ardently championed in England by Professor James Geikie; who has endeavoured to show that there were in Europe six distinct glacial epochs within the Glacial period, separated by five epochs of more moderate temperature.
Although it is admitted that no strict correlation of the European and North American stages is possible, it has been suggested that the Aftonian may be the equivalent of the Helvetian; the Kansan may represent the Saxonian; the Iowan, the Polandian; the Jerseyan, the Scanian; the early Wisconsin, the Mecklenburgian.
