1985 Map of Shungnak A-4

USGS Topo · Published 1985

About this map

The Continental Divide winds through this interior Alaskan landscape, marking a significant topographic transition within the Koyukuk National Wildlife Refuge. Based on 1971 aerial photography and edited in the mid-1980s, the map reveals a wilderness largely devoid of permanent settlements, defined instead by drainage patterns and remote peaks. Waterways like Billy Hawk Creek flow through the northern reaches, while a solitary Tractor Trail in the northeast corner provides the only evidence of overland mechanized travel across the tundra. Notable landmarks such as Bush and Octupus serve as primary points of orientation in a region dominated by elevation contours and seasonal wetlands. This provisional survey captures the territory as it was managed prior to further modern infrastructure, preserving the original hydrography and natural boundaries of the refuge.
