1956 Map of Coleen A-1

USGS Topo · Published 1973

About this map

The United States Canada international border defines the eastern edge of this territory, where the topography was documented through aerial photography in the mid-1950s. The landscape is dominated by the westward flow of the Salmon Trout River and the northern reaches of the Campbell River. These waterways carve through high terrain marked by prominent survey points such as VABM Smith and Arch. Published by the Geological Survey with data from the International Boundary Commission, the map illustrates a wilderness area entirely devoid of roads or trails. This remote corridor along the Alaska Yukon line represents a segment of the northern interior where the natural drainage patterns of the rivers were the primary geographical markers before any modern infrastructure reached this section of the frontier.
