The **Bering Strait Land Bridge** was a land bridge roughly 1,000 miles (1,600 km) north to south at its greatest extent, which joined present-day Alaska and eastern Siberia at various times during the Pleistocene ice ages. A Land bridge is a land connection that joins together separates areas, which allows animals and people to migrate or go across.

Humans migrated across the pacific during the last ice age, which was 11,500 years ago. During the Ice age much of Earth’s water was locked up in glaciers. Glaciers are en extended mass of ice formed from snow fall making a large persistent body of ice. The result of this was seas water level lowering, so that it exposed land previously underwater.

It may still hold archaeological information and provide answers to questions about who the first people were to come to North America. Another name for the Bering land bridge is Beringia. As these glaciers grew,sea levels fell and in several places across the planet some land became exposed forming what is a land bridge. It is believed that there were not many or few trees and all vegetation consisted of grasses and low lying plants and shrubs. This is because the land bridge was not glaciated and precipitation was light, grasslands were most common on the Bering Land Bridge. Itself and for hundreds of miles into the Asian and North American continents there were most likely grasslands.

This book was about. The theory of how people migrated and the way they lived their life. For example it talked about what the people hunted, gathered, and how they survived while migrating. This book talked about not just people but animals too. For example it told about mammoths and smaller animals that migrated to the Americas over The Bering Strait. //Aveni Anthony//. 1. New York : Scholastic Nonfiction, 2005. Print. There is evidence that saber tooth cats, woolly mammoths, various ungulates and plants were on the Bering Strait land bridge. An animal that migrated across the land bridge is the mammoth.

A mammoth was an animal that is bigger than our elephants today. Scientists have a theory that mammoths used their tusks as snow plows to dig through grass and snow. A tusk is a tooth outside a mammoth usually one of a pair. A tusk is also called a tush! Prehistoric people would hunt the mammoth for different parts of their body. And since they were so huge there was much matter they could use. The people would try to never waste any part of the animal.

Historical Importance The Bering Land Bridge is believed to have existed through many or numerous ice ages from earlier ones around 35,000 years ago to more recent ice ages around 22,000-7,000 years ago. === **HYPOTHESIS:** Without the Bering Strait land bridge many animals would may not have been here and maybe even people! This is a great deal of importance and should be recognized more than it is today! ===
