An artist's impression of the last glacial period at glacial maximum [4]. The LGP is often colloquially referred to as the "last ice age", though the term ice age is not strictly defined, and on a longer geological perspective, the last few million years could be termed a single ice age given the continual presence of ice sheets near both poles.
To geologists, an ice age is defined by the presence of large amounts of land-based ice. Prior to the Quaternary glaciation, land-based ice formed during at least four earlier geologic periods: the late Paleozoic (360–260 Ma), Andean-Saharan (450–420 Ma), Cryogenian (720–635 Ma) and Huronian (2,400–2,100 Ma).

Analyzing the ice could help to test theories about how it refroze beneath the ice sheet. Researchers will also determine whether even older ice, such as that from the pre-Quaternary Period 2.58 ...
What is probably the world's oldest ice, dating back 1.2m years ago, has been dug out from deep within Antarctica. ... Million year-old bubbles could solve ice age mystery. ... Oldest Ice they ...
Scientists warn that the Earth is just 15 years away from experiencing a "mini ice age" — something that hasn't happened in 300 years. Researchers in the U.K. created a new model of the Sun ...
Much of modern Finland is former seabed or archipelago: illustrated are sea levels immediately after the last ice age. Erratic boulders, U-shaped valleys, drumlins, eskers, kettle lakes, bedrock striations are among the common signatures of the Ice Age. In addition, post-glacial rebound has caused numerous significant changes to coastlines and ...
This area was covered by an ice field during the last ice age, and preliminary data from Hall’s research suggest the ice had collapsed back to its center by around 18,000 years ago.
