1952 Map of Unalakleet A-4

About this map

The Anvik River dominates this interior Alaskan landscape, meandering through a broad valley floor characterized by wetlands and braided stream channels. Surveyed in the early 1950s, the terrain shows a clear transition from the marshy lowlands of the river basin to the steep, unnamed ridges rising to the west. This 1:63,360 scale topographic study captures the hydrological network of the region, including the eastern confluence of Canyon Creek and the southern drainage of Runkels Creek. To the west, the Swift River parallels the main valley, carved into the higher elevations. The lack of established roads or structures in this area underscores the wilderness character of the Yukon-Koyukuk region during the mid-twentieth century, as documented by the Army Map Service using early photogrammetric methods.
