1970 Map of Beaver A-6

About this map

The Fort Hamlin Hills dominate the southern portion of this interior Alaskan landscape, providing a sharp contrast to the water-dense lowlands to the north. At the start of the 1970s, this region remained largely untouched by permanent development, characterized instead by an extensive network of lakes and waterways. The Dall River meanders through the central terrain, feeding into and out of significant water bodies like Guishiemana Lake and the Little Sussaymin Lakes. A singular Winter Road cuts across the northeastern corner, tracing a path that highlights the seasonal nature of transportation and survival in the Yukon-Koyukuk region before the expansion of modern infrastructure. The map preserves the complex drainage patterns and topographical transitions of a wilderness area defined by its hydrology.
