Interior Alaska is the largest region of the U.S. state of Alaska, which includes much of the inland area of the Wrangell Mountains and the Alaska Range with Mount McKinley. In the north it is bounded by the Brooks Range. Low hills with poplar and birch forests cover the region.
In addition to Fairbanks, Alaska's second largest city, are home to villages Tok, Talkeetna, Eagle, Glennallen, Delta Junction, Nenana, Healy and Cantwell in Interior. The Trans - Alaska Pipeline crosses the region from north to south. The Yukon flows from Canada coming through the interior to the Bering Sea.
The interior is a zone of permafrost diskontinuierlichern with a tendency for the continuous permafrost near the Arctic Circle. On clear winter nights, northern lights can be seen in the sky.

The average temperature in Fairbanks lie at -24 ° C in winter and 17 ° C in summer. The lowest temperature in the Interior in 1971 measured with -62 ° C at Prospect Creek.
