1956 Map of Black River D-3

About this map

Negrohead Mountain dominates the southern landscape of this interior Alaskan wilderness, rising above a complex network of wetlands and subarctic watercourses. Surveyed in the mid-1950s, the terrain is defined by its drainage patterns, with Rat Creek winding through the northern reaches while Kevinjik Creek and David Creek carve through the varied elevations of the east and south. This document illustrates a remote region of the Yukon-Koyukuk area before significant modern modification, where the Bureau of Land Management identified vast tracts of unsurveyed and unmarked lands. The intricate depiction of marshes and small lakes highlights the hydrological character of the Black River basin, providing a record of the natural topography as it existed in the mid-20th century.
