Major ice ages occurred during the Precambrian (~800-600 million years ago), the Ordovician to Silurian (~470-430 million years ago), the Carboniferous to Permian (~350-250 million years ago), and in the Pleistocene and Holocene Epochs (~2.6 million years ago to present).

Sep 1, 2010 · The last period of glaciation, which is often informally called the “Ice Age,” peaked about 20,000 years ago. At that time, the world was on average probably about 10°F (5°C) colder than today, and locally as much as 40°F (22°C) colder. What causes an ice age and glacial-interglacial cycles?

Dec 22, 2011 · What is an ice age? An ice age is a long interval of time (millions to tens of millions of years) when global temperatures are relatively cold and large areas of the Earth are covered by continental ice sheets and alpine glaciers.

Jul 20, 2023 · In 2018 paleontologists identified the skeleton of a horse from the ice age in Lehi, Utah — a particularly unusual discovery given that much of the western part of the state was underwater until about 14,000 years ago.

Dec 30, 2024 · VERNAL, Utah — A team of scientists from the Utah Division of State Parks and the USDA Forest Service Ashley National Forest, along with a group of Utah cavers, have recovered the nearly complete skeleton of a red fox dating back to the Ice Ages in a cave in the Uinta Mountains of northeastern Utah.

Dec 3, 1997 · The last time Utah weathered an Ice Age, around 12,000 years ago, our animals were as big and varied as the wildlife of Africa. Utah was home to creatures much like elephants - mastodons and woolly mammoths.

Nov 10, 2014 · The last 30,000 years of Utah’s Ice Age were characterized by increasingly volatile shifts in climate. The changing norms in temperature and abundance of liquid water created cyclical periods of transitioning habitat.

Jan 7, 1990 · Utah's Ice Age - stretching from about 1.8 million years ago to 10,000 years ago and known to geologists and natural scientists as the Pleistocene Epoch - was a period unlike any other, says Frank DeCourten, assistant director and adjunct professor of geology at the Utah Museum of Natural History.

"Ice Age" Visualization. This interactive globe app helps to visualize how the Pliestocene 'Ice Age' may have actually been a period of altered polar axis (ie. the north pole was over greenland instead of its present location). Us geologists refer to a change in the earth's rotational axis as 'True Polar Wandering Events' (TPW). Such events are ...

This paleontological record allows us to chart a faunal history for northern Utah during the Ice Age that reflects climatic fluctuations brought about by the waxing and waning of glaciers, the rise and fall of glacial lakes such as Lake Bonneville, and modifications of vegetation zones.
