About this map

Tonsina River and the Copper River dominate this interior Alaskan landscape, where the primary transport corridor follows the Richardson Highway. This mid-century survey captures the settlement at Tonsina and the nearby Gaglow Siding during a period when remote transportation infrastructure was critical to the region's connectivity. The map identifies key aviation and transit points like a Landing Strip and various benchmark stations used for high-altitude navigation.

The topography is defined by high peaks such as Mt Durelle and a series of triangulation stations, including VABM Tonsina and VABM Bernard. From the waters of Tonsina Lake to the drainage of Squirrel Creek, the drainage patterns illustrate a complex river system feeding into the Copper River basin. Cultural markers like a small Cem near the highway and active Gravel Pits reflect the small-scale human footprint in this wilderness.
