Alaska's Foundation of Human Activity

Did you guys know that one of the first populations of Alaska was Indians? Like other parts of USA, Indians already existed before European colonization. My question is: what Indians were doing there in that cold climate? How did they get there from all the places? They were located on the north east interior, probably because this part of Alaska has large agriculture opportunities. Eskimos really did make out a good amount of population (you can take a look at this interesting youtube video: http://www.youtube.com/watch?v=b-XP30aG8bE) .

Aleuts were also the main population of Alaska. Their name was given by Russians traders in the 18^th century. In European exploration of Alaska began in 1741 and in 1792, a few fur trade companies were established.

Why Russian traders did not established in Alaska? The climate of Russia and Alaska is pretty much the same; for some reasons, Alaska did not appeal that good to Russians.

Alaska was purchased from Russian in the 19^th century and most of the late immigration came from USA. The Gold Rush of late 19^th century and the Oil Boom of 1970s contributed to Alaska’s increase of population.

This is the check which was written for the Alaska's purchase:

Some facts from www.city-data.com show that urban population increased from 64.5% in 1980 to 67.5% in 1990 and between 1995 and 1998 the population increased 2.1%. All these numbers indicates that Alaska’s population increases. But is this following the general trend of increasing USA’s population or it is Alaskan specific??
