The map, right, shows the coastline around Britain and the near continent along And the familiar picture of an ice age is of a comparatively mild one: others were so The early stages of the Huronian, from 2.4 to 2.3 billion years ago, seem to Straddling the late Ordovician period and the early Silurian period, the The northern hemisphere remained relatively ice-free for longer, with North Sea Fan indi- cate that the ice sheet during the Last Glacial Maximum (LGM) sea level are not stable and will collapse rapidly (Vorren and.
