The Athabascan speaking people was the third and last major migration of the postdiluvian people, well, that is so, in a sense of those people who migrated across the Beringia land bridge. This migration occurred somewhat later in time, possibly one hundred to two hundred years later than the previous crossings of the same land bridge.

Those of this final major migration, who came across the land bridge, traveled into the interior and began settling in the eastern portions of the Alaskan Pacific Coast Range region, Basin and Range region and Rocky Mountains region, avoiding the western and southern area of the Pacific Coast Range region where their dwelt the Sons of Joktan. Some time later, theses tribes expanded eastward and south into Canada to settle the Yukon and British Columbia areas of the Basin and Range region, Rocky Mountain region, Interior Lowland region, Canadian Shield region and the extreme northern area of the Hudson Bay portion of the Canadian Lowlands region. Later, the Athabascan tribes moved southward both along the coastal areas as well as into the interior central lakes region. Sometime later, these Athabascan speaking people moved into the area now know as the United states, both along the Pacific Coast as well into the interior Basin and Ranges areas.

Some of these migration would become the ancestors of the Na-Dené speaking people of today, which includes the present day Apache and Navajo. The Navajo language is the most populated of all of the Athabascan cultures today and the best known Athabascan language.

Son of Aram, Ge´ther was born third of four sons and father of the following sons: 1. Deg Xit'an, 2. Tutchone, 3. Slavey, 4. Chipewyan, 5. Chilcotin, 6. Tsuut;ina, 7. Tlicho, 8. T'atsaot'ine. 9. Kwalhiokwa, and 10. Appachean.

Gether and his sons begin to travel into the new continent, and along the way, one of his sons would decide to take on a different path than that of Gether and the rest of his sons. As Gether continued into the land, more of his sons would begin their own Journey On™.

The Athabascan people are largely defined by their language, and Athabascan languages are spoken in large areas of Alaska, in four areas of Canada, on the US Pacific Coast as far south as northern California and in the US Southwest. The Athabascan language family has, in fact, the greatest geographic spread of any language family in North America. Because of this, great diversity is to be found among the Athabascan peoples. It is therefore difficult to make generalizations about the Athabascan culture or the Athabascan history, simply because, there are, in fact, many Athabascan cultures and many Athabascan histories.

However, in one respect, it can be generalized that the Athabascan people were, at least at first, hunters and gatherers who were highly nomadic, traveling mostly in family groups to fish, hunt, and trap.

We do know that the Athabascan languages are related to the Tlingit language people of extreme southeast Alaska, however, not to the Eyak language people who live in the same coastal lands because the Eyak are instead an Algonquian language of the Sugpiag Alutiig tribe. However, both tribes of people who speak the languages of the Tlingit and Eyak are spoken mainly in Southeast Alaska and have spread out into adjacent Yukon Territory. Too, most archaeologists tend to believe that the Eyak and Tlingit originated in southeast Alaska, however, it is more likely that the people who are the Algonquin Eyak, as well as the Athabascan Tlingit all migrated to Alaska from some where on the Asian Continent.

Nevertheless, it seems likely that the homeland of all of the Athabascan peoples was at one time in history in southeast Alaska, perhaps on the coast or even in the interior, including the large lakes that form the source of the Yukon River. From these large lakes, the Athabascan tribes, which now have divided into at least ten cultures, which have spread west in Alaska along the Yukon and Tanana Rivers, then, south into British Columbia and also further both eastward and southward through Canada.

It is evidently from the numerous homelands of the Athabascans, that various bands and/or cultures of the Athabascan people accomplished other great migrations: south along the Pacific Coast, down along the east side of the Rocky Mountains into the American Southwest, across the northern Great Plains, even as far east across the northern interior of Canada as as Hudson Bay.

Some who study this, believe that these expansions were facilitated by the distinctive hunting techniques of the Athabascans, often involving the entire community, as when they would drive game animals into a bottleneck canyon or narrowed place where they could easily be killed. This communal hunting style gave them a competitive advantage, making it possible for bands of Athabascans to flourish in marginal areas where other groups found it difficult to survive. Some also think that the Athabascans were first along the Northwest Coast to use the bow and arrow, especially since this type of weapon appears to have spread down from the north just at the time when we would expect the Athabascan migration to have occurred.

Athabascan people have traditionally lived along five major river ways: the Yukon, the Tanana, the Susitna, the Kuskokwim, and the Copper River drainages.

There are seven cultural branches of the Athabascan speaking people.

While most First Nations in the Yukon territory are a part of the wider Dene Nation, (or what is more commonly called the Northern Athabaskan languages) there are the Tlingit and Métis nations that provide a larger spectrum of indigeneity that links some within the Yukon Territory with non-Athabaskan people.

The cultures in the British Columbia area is divided into two general groups, northern and southern. The Language groups in this area include:

This large Athabascan group of cultures are very similar to the British Columbia culture in both language and culture.

Although the only culture in the Canadian northern plains, it is close in affinities with tribes of the US Cultures, both the southern and the coastal.
