1956 Map of Fort Yukon A-3

About this map

Birch Creek winds through the northern reaches of this interior Alaskan landscape, defining a complex network of oxbow lakes and interconnected wetlands. Photogrammetric methods from the early 1950s captured this transition between the low-lying basin and the higher elevations to the south, where Discovery Creek emerges from the hills. The terrain is marked by significant hydrological features including Egil Island, positioned among the dense river loops that characterize the northern corridor. Surveyed primarily from aerial photographs, the map reflects the unsurveyed and unmarked nature of the land at the time, with land lines predetermined by the Bureau of Land Management rather than ground-based marking. This specific sheet focuses on the wilderness south of the Yukon River, where the meandering drainage patterns of the Birch Creek system dominate the landscape. Remote triangulation points like Vabm 482 provide the few fixed markers in an otherwise fluid environment of shifting streams and marshes.
