The 'Tanana Valley' is a lowland region in central
Alaska in the
United States, on the north side of the
Alaska Range where the
Tanana River emerges from the mountains.
The region experiences great extremes of temperature during the year. During the winter months, the air is prone to
stratification due to temperature inversions, leading to thick fogs. During the summer, the surrounding plains are generally boglike, and include much
permafrost and many
pingoes.
The Tanana Valley is the most populated area of Alaska north of the Alaska Range. Its largest city is
Fairbanks. Other communities include:
