Tetlin Wildlife Refuge

This extensive area is dotted with lakes, swamp, marshes, low growing forest and the second largest river system in Alaska, the Tanana River. Known as the valley of great migrations, the northern border of this refuge stretches for 65 miles along the Alaska Highway.

It is a refuge for hundreds of thousands of migratory birds. There have been recent bear sightings close by.

The centre is of log cabin construction with a grass roof. An elevated cache is adjacent to the visitors' centre. The cache is for storage of essential supplies to keep them safe from bears and other wildlife.

As we drive towards the border, we go through a really swampy area that is constantly changing. Buildings and Telegraph poles lean precariously as the subsoil around the permafrost is under constant sinking.もっと詳しく
