1970 Map of Beaver A-6

USGS Topo · Published 1987

About this map

Guishiemana Lake and the complex hydrology of the Yukon Flats define this subarctic interior landscape. Recorded through aerial photography in 1970, the area shows a vast network of unnamed ponds and interconnected waterways, including the Dall River, Little Dall River, and the Sussaymin Lakes system. To the south, the topography shifts abruptly into the Fort Hamlin Hills, where prominent elevations like Nokuy rise above the alluvial plain. The map documents a sparse human imprint on the land, most notably the seasonal Winter Trail cutting across the north and the designation of the National Wildlife Refuge, which encompasses a significant portion of these wetlands. This survey provides a baseline of the regional terrain before modern environmental shifts, capturing the precise drainage patterns of Hamlin Creek and its surroundings.
