1955 Map of Bradfield Canal C-5

About this map

Katete River flows through the heart of this mid-century survey, cutting through the glacially carved landscape of the Tongass National Forest. The map documents a critical segment of the international boundary where British Columbia and Alaska meet, following the high ridge lines between Mt Whipple and Mt Fawcett. This cartographic record, based on 1948 aerial photography and 1955 field annotation, captures the transition from United States territory into Canada. The topography is defined by sharp elevation changes and high mountain peaks, illustrating the isolation of the boundary region before the development of modern infrastructure in the area.
