1956 Map of Fort Yukon A-4

About this map

Lower Mouth Birch Creek meanders through the northern lowlands of this 1956 survey, where the landscape transitions from saturated wetlands to more defined terrain. The region is characterized by a dense network of water bodies, including the prominent Chloya Lake and the aptly named Three Lakes group. The topography reveals a complex drainage pattern where Discovery Creek winds through the northeastern section, and Twin Island Lake sits centrally within the marshy flats. Toward the southwest, Burman Lake anchors the more elevated, lake-strewn portion of the quadrangle. This interior Alaska wilderness, mapped through aerial photography in the early 1950s, remains largely undeveloped, showing the natural state of the Yukon-Koyukuk region before significant modern influence.
