1986 Map of Hughes B-5

About this map

The Continental Divide winds across the high terrain of this Alaskan interior landscape, separating the drainage systems of the north from the river valleys to the south. The Hogatza River dominates the lower half of the quadrangle, exhibiting a complex, meandering path through low-lying marshlands and meadows. This hydrological pattern indicates a slow-moving, mature river system that creates a labyrinth of oxbows and seasonal wetlands. In the southern reaches, the Babantaltlin Hills rise above the basin, with Babantaltlin Creek and the Pah River feeding into the wider watershed. The lack of roads or established settlements on this mid-1980s provisional sheet underscores the isolation of the Yukon-Koyukuk region, where the primary geographical landmarks are the watercourses and significant elevation shifts of the divide.
