1956 Map of Tanacross B-2

About this map

The Ladue River meanders through this section of the Yukon-Tanana Uplands, defining a landscape of high-latitude drainage and isolated survey markers. This map depicts the subarctic terrain before significant human infrastructure reached this portion of the interior, focused instead on the natural hydrology of the South Fork and the surrounding marshy lowlands. Surveyors established essential horizontal control at points like Vabm Bbgm-1 3596, while identifying permafrost-related features such as a Pingo, which are characteristic of this region's geomorphology. The lack of roads or established settlements on this sheet highlights the wilderness state of the Alaskan interior in the mid-1950s, where land lines represent only unsurveyed and unmarked locations predetermined by the Bureau of Land Management.
