1951 Map of Taku River A-4

About this map

The Coast Mountains dominate this 1951 topographic study, defining the international boundary between British Columbia and Alaska. This high-altitude landscape, much of it preserved within the Tongass National Forest, is characterized by steep glacial terrain and ice-fed drainages like the Whiting River and Crescent Lake. For surveyors and cartographers, the map serves as a detailed record of geodetic control points along the frontier, marking elevations such as VABM Snowy 5960 and VABM Cook 5156. The placement of markers like Mon 82 and Mount Hill Boundary Peak 78 illustrates the precise effort required to delineate this remote mountain territory during the mid-twentieth century.
