1955 Map of Circle A-1

About this map

The Salcha River and its numerous tributaries dominate this mid-century topographic survey of the interior Alaskan wilderness. Surveyed using photogrammetric methods in the 1950s, the map reveals a landscape defined by water and elevation, where names like Caribou Creek and Big Windy Creek hint at the local environment. A single Cabin stands as the only named structure, illustrating the sparse human presence in this region during the post-war era. The western boundary is marked by a large Military Reservation, while the Fairbanks North Star Borough line crosses through the eastern reaches. The terrain is a complex network of drainages including the Yukon Fork and South Fork Birch Creek, providing a detailed record of the drainage patterns and geographical landmarks of this section of the Yukon-Koyukuk region before more modern infrastructure or changes occurred.
