1955 Map of Nulato D-6

About this map

The Gisasa River snakes through the center of this remote Alaskan interior landscape, its meandering course carving through a vast network of hills and valleys. This 1950s-era topographic survey, though minimally revised in 1984, documents a region largely defined by its natural drainage systems rather than human infrastructure. The Kateel River serves as the primary longitudinal reference point for the land grid, while smaller tributaries like Arvesta Creek feed into the larger river basin. The absence of roads, settlements, or structures on this sheet underscores the isolation of the Yukon-Koyukuk region at the time of mapping, providing a baseline for environmental studies or land-use research in this part of the Nulato quadrangle. The map relies on 1950s aerial photography to delineate the complex topography and river patterns that govern the local geography.
