1951 Map of Taku River A-4

About this map

The international border between Canada and the United States defines the eastern edge of this high-altitude landscape within the Tongass National Forest. Surveyed in the mid-twentieth century, the map documents a series of critical survey points along the Alaska and British Columbia line, including Boundary Peak 83, Boundary Peak 79, and Boundary Peak 78. The terrain is dominated by significant peaks such as VABM Cook 5158 and Mount Hill, which rise above heavily glaciated basins. Hydrological features are centered on the Whiting River corridor and the alpine Crescent Lake. This 1951 field-annotated study provides an exact record of the remote coastal range's topography before modern glacial recession, marking the precise monuments used to delineate the frontier.
