About this map

Tanana River and its intricate braid of channels dominate this mid-century interior Alaskan landscape, where the confluence of the Gerstle River and Clearwater creek meet the primary waterway. The mapping captures a network of seasonal access routes and remote outposts, including several Cabins and the Clearwater Ranch located south of the main river fork. To the north, the Goodpaster River meanders through the Goodpaster Flats, a broad marshy basin punctuated by Liscum Slough and surrounded by prominent landmarks like Volkmar Lake.

A functional Winter Trail cuts across the northern terrain, indicating the importance of cold-weather transport in this subarctic environment. The presence of named watercourses like Sawmill Creek and Granite Creek suggests the primary drainage patterns of the era before significant modern infrastructure. This 1950s survey provides a detailed look at the hydrology of the Tanana Valley and the sparse, river-oriented human presence in the region.
