About this map

The massive expanse of Tetlin Lake dominates this 1948 landscape, serving as a central hub for a complex network of wetlands and river systems. To the north, the Tanana River and Tok River wind through low-lying flats, while the Tetlin Hills rise to provide topographic relief. The settlement of Tetlin is located near the eastern shore of the lake, featuring a Cem and a Landing Strip that suggests the importance of bush aviation in this interior Alaskan region.

South of the main water body, a dense concentration of smaller lakes like Gasoline Lake, Dathlalmund Lake, and Old Albert Lake fill the basin. The presence of a Fish and Wildlife Camp near Island Lake reflects the area's significance as a habitat for migratory birds and local fauna. High points such as Chisana Mountain and the Last Tetlin Hill bound the southern and eastern horizons, framing a wilderness defined by water and permafrost.
