About this map

The interior of the Yukon-Koyukuk Census Area is meticulously charted in this topographic study, revealing a landscape dominated by complex drainage patterns and elevation changes. Bear Mountain Cr emerges in the southeastern corner of the quadrangle, serving as the primary named hydrological feature in this expanse of the eastern Alaska wilderness. The map details the precise township and range divisions, including t15n r23e and t14n r23e, which provide the essential spatial framework for land management and remote navigation in this unpopulated region. The intricate contour lines illustrate the high-relief terrain that characterizes the divide between various drainage basins, offering researchers a clear view of the natural geography before any modern human development.
