1956 Map of Charley River A-6

About this map

Salcha River and Birch Creek headwaters dominate this interior Alaskan landscape, which was photogrammetrically mapped in the mid-1950s. The survey reveals a vast network of drainages including Coal Creek, Sterling Creek, and Woodhopper Creek that carve through high-elevation terrain. This specific quadrangle covers a remote area of the Yukon-Koyukuk region characterized by the Yukon River South Fork, where many land lines remained unsurveyed and unmarked during the time of publication. The intricate contour work illustrates the complex drainage patterns of the northern wilderness before modern infrastructure touched these specific coordinates. Researchers can trace the courses of lesser-known waterways like Hanna Creek and Webber Creek as they appeared prior to the era of contemporary satellite mapping.
