1956 Map of Black River D-1

About this map

The Salmon Trout River meanders across this interior wilderness along the international boundary, a landscape defined by sharp elevation shifts and remote survey points. Mapped via aerial photography in the mid-1950s, the terrain shows no established roads or trails, reflecting a truly untouched portion of the northeastern Alaskan borderlands. Vertical control stations like VABM 3651 Storm and VABM 2144 Lone stand as isolated landmarks for bush pilots and surveyors navigating the high ridges above the river valley. The eastern edge of the sheet follows the United States Canada border, marking the transition from Alaska into the Yukon. This area is dominated by the drainage system of Fort Creek and the high point at VABM 3420 Fort, offering a precise record of the topographical relief in a region where few human footprints are recorded.
