1954 Map of McGrath A-6

About this map

The Tatlawiksuk River winds through this interior landscape as it appeared in the mid-1950s. Surveyed during an era of expanding aerial photogrammetry, this topographical study by the Geological Survey documents a region defined by complex drainage patterns and low-lying wetlands. The presence of Shifting Sand along the river banks indicates a dynamic fluvial environment where watercourses frequently alter their paths across the alluvial plains. Unlike many contemporary maps of more developed regions, this 1954 sheet reveals a territory entirely devoid of roads or trails, providing a primary source for understanding the pristine hydrological state of the Yukon-Koyukuk region before any modern infrastructure or human impact.
