1955 Map of Umiat A-5

About this map

Naval Petroleum Reserve No 4 dominates the northwestern portion of this mid-century survey, a region defined by its strategic resource potential and remote Arctic hydrology. The braided path of the Colville River carves through the northern landscape, where an intricate network of wetlands and seasonal watercourses like Mud Creek feed into the main channel. Moving south, the terrain transitions into the complex drainage systems of Fossil Creek and Ninuluk Creek, reflecting a land shaped by permafrost and northern runoff. Mapped by the U.S. Army Topographic Command using 1955 aerial photography, this sheet represents a technical effort to document the unsurveyed and unmarked boundaries of the Bureau of Land Management Folio U-10. The lack of established roads or permanent settlements highlights the area's status as a primitive wilderness during the early Cold War era of Arctic exploration.
