1952 Map of Tanacross A-4

About this map

The Tetlin Indian Reservation dominates this 1948 aerial survey of the Alaska interior, centering on the massive Tetlin Lake. This vast drainage system is defined by the winding paths of the Tok River and the Tanana River to the north, which carve through the Tetlin Hills. The landscape is a complex network of wetlands and smaller water bodies, including the Gasoline Lakes and the Tetlin River, showing the seasonal hydrology of the Fourth Judicial Division before modern development. Evidence of human presence is concentrated around the Airstrip Tetlin and scattered Cabins along the water's edge, highlighting the reliance on bush aviation and river travel. Significant high points such as Chisana Mountain provide navigational landmarks in a region defined by its shifting braided rivers and marshlands.
