1956 Map of Charley River B-1

About this map

The Nation River flows through this remote stretch of the Alaska-Yukon border, carving a path between the Step Mountains and the high points of Mount Casca. Surveyed in the mid-1950s, the terrain is defined by its complex drainage network, where Waterfall Creek, Ettrain Creek, and Tindir Creek converge toward the river valley. The map documents the international boundary where the Alaska Yukon line meets the United States Canada border, a region largely unpopulated and marked only by surveyor benchmarks like VABM Step and VABM Nation. Geologic interest is found in the northern reaches, where the presence of Pingos indicates the permafrost-driven landforms characteristic of this subarctic environment. The survey reveals an untouched landscape of steep ridges and creek bottoms before modern developments reached this corner of the Southeast Fairbanks area.
