During maximum glaciations of the pleistocene epoch, there was much more glacial ice on the olympic mountains and some glaciers extended far down the valleys to the coastal plain. During the times of cold climate in the pleistocene, unglaciated parts of the interior of the western united states received much more annual snow and rain than they.

While homo sapiens evolved, many vertebrates, especially large mammals, succumbed to the harsh climate conditions.
Before the pleistocene throughout much of the earth's history, long before humanity came onto the scene (from say 2,000 million years ago to 2 million years ago), the global climate was much warmer than now, with the global mean temperature as much as 8°c to 15°c warmer than it is today.
126 ma), is also known as the ice age, pleistocene glaciation, or quaternary glaciation. The pleistocene has been characterized by temperature fluctuations over a range of almost 10°c on time scales of 40,000 to 100,000 years.
Human involves the interaction of air, water, land, polar ice, and all organic life.
Change, variation, replacement or extinction marked life associations even before man became a part of the environment of that great plant and animal life of the past. Fossil records of the pleistocene epoch range from massive tusks and skeletons of mastodons to pollen grains and spores as minute as ten microns in diameter.

Before the pleistocene glaciation, ohio was much different than today. Lake erie did not exist and a major river, the erigans river, flowed in a wide valley where the lake is today. Much of ohio was drained by an ancient river, known as the teays, that had headwaters in north carolina and flowed northward across virginia and west virgina.

The pleistocene has been characterized by significant temperature variations (through a range of almost 10°c) on time scales of 40,000 to 100,000 years, and corresponding expansion and contraction of ice sheets.

As the study of the pleistocene period has intensified, we now know that glacial-interglacial cycles also corresponded to: more pronounced temperature changes in the high latitudes than the low latitudes (regions near the tropics). Temperature changes in high latitude regions are thought to be about 10 o c between glacials and interglacials.
It is important to recognize that the pleistocene was a series of actual glaciations, separated by relatively short inter glacial periods. 6 million years ago and lasted until the end of the glaciation.

The end of the pleistocene epoch (20,000 to 12,000 years ago) was marked by a global ice age, which led to the extinction of many megafauna mammals. What most people don't know is that this capitalized ice age was the last of no less than 11 pleistocene ice ages, interspersed with more temperate intervals called interglacials.
During the pleistocene epoch there were four completely separate glacial advances in north america (stovall and brown, 1955). The advances were separated by long intervals of ice withdrawal, sufficient to permit the previously occupied area covered by ice to be reoccupied by plants and animals.
Years, severe climatic changes had tremendous influence on life on earth. During the pleistocene, the earth experienced numerous glacial-interglacial cycles. At the maximum extent of the last glacial period, ice sheets extende.

The last glacial maximum (lgm) occurred about 20,000 years ago, during the last phase of the pleistocene epoch.
