About this map

The United States Canada international border defines the eastern edge of this landscape, documented through aerial photography taken in the early 1950s. This territory within the Alaska Yukon frontier is characterized by high-elevation drainage systems and remote survey points. The northern flow of McArthur Creek and the winding course of Gardiner Creek dominate the interior, their valleys carved between prominent summits such as VABM Bump and VABM Flat.

A series of boundary markers, including Mon 148 through Mon 153, provide fixed reference points along the straight-line border, illustrating the precision of the International Boundary Commission's work in this subarctic environment. The map details a wilderness prior to modern development, where topography was determined via multiplex methods to chart the intricate network of peaks and watercourses that define the Alask-Yukon divide.
