About this map

The Alaska Yukon boundary defines the eastern edge of this 1950s interior landscape, where the United States Canada border meets the high country of the eastern interior. The Grayling Fork Black River dominates the central portion of the map, carving a wide path through a terrain defined by significant elevation markers and isolated peaks. This region is characterized by its drainage networks, including Tikan Creek and the meandering Bull Creek to the south.

Prominent landmarks such as Steamboat Mountain and Midnight Hill provide essential orientation in a wilderness largely void of human infrastructure at the time of the 1956 field annotation. Surveyors established several Vertical Angle Bench Marks to map the relief, including Vabm 3515 Blue and Vabm 2801 Tom. The absence of roads or trails on this sheet emphasizes the remoteness of the region during the mid-twentieth century.
