2016 Map of Hughes A-5 SW

About this map

The Koyukuk River and its major tributary, the Hogatza River, dominate this section of the Alaskan interior in the early 21st century. The map reveals an intricate network of oxbow lakes and meandering sloughs across the river valley, illustrating the constant shifting of these waterways over time. Rising above the wetlands and floodplains, Sixmile Pass serves as a distinct break in the local topography. This remote landscape, defined by seasonal water flow and drainage patterns like Hogatzakhotak Cr and McLanes Creek, remains largely untouched by permanent road infrastructure. The map records the complex hydrology of the Yukon-Koyukuk region, where the rivers serve as the primary geographical markers for navigation and land management.
