1952 Map of Unalakleet C-3

About this map

The Chiroskey River winds through the northwestern reaches of this remote interior landscape, illustrating the complex drainage patterns of the Yukon-Koyukuk region in the early 1950s. Surveyed by the Army Map Service using aerial photography, the terrain is characterized by intricate contour lines that reveal the high-elevation divide between major western Alaskan watersheds. In the southeastern corner, the upper reaches of the Anvik River begin to take shape, eventually feeding toward the Yukon. The lack of any marked roads, trails, or settlements highlights the wilderness character of the area during this era of mapping, where natural waterways served as the primary landmarks for navigation and land management by the Bureau of Land Management.
