1956 Map of Coleen A-1

USGS Topo · Published 1959

About this map

The Salmon Trout River flows through this high-latitude terrain, winding toward the international boundary where the Alaska Yukon border meets. This mid-century survey by the Geological Survey and International Boundary Commission documents a landscape defined by sharp elevation shifts and unnamed peaks, punctuated by survey control points like Vabm 1930 and the triangulation station at Smith. In the northern section, the Campbell River cuts through the topography, which transitions from river valleys to high ridges such as Arch 2. The absence of roads or established settlements emphasizes the remote nature of this portion of the United States Canada border, serving as a snapshot of the region before modern digital mapping, based on aerial photography taken during the 1950s.
