1956 Map of Black River A-5

About this map

The Little Black River winds through this interior Alaskan landscape, characterized by a complex network of wetlands and small water bodies. Mapped by the Geological Survey using aerial photographs from the mid-1950s, the terrain reveals a sparsely populated region where natural watercourses are the primary geographical markers. The eastern edge of the quadrangle is defined by the braided path of the river, which creates a series of marshes and ponds as it moves through the low-relief valley. Along the southern portion of the sheet, Paddle Creek serves as a significant tributary, contributing to the drainage of the surrounding unmapped and unsurveyed land lines. This survey captures the wilderness prior to modern development, providing a clear record of the hydrological patterns and topographic elevations that dictated movement through the Yukon-Koyukuk region during the mid-twentieth century.
