1958 Map of Tyonek D-6

About this map

Skwentna River and the braided glacial drainages of the Susitna Basin dominate this 1950s landscape, captured before extensive modern development. The map reveals a complex network of waterways, including the Hayes River and Trimble River, which wind through the terrain from the higher elevations of Dickason Mountain. A single Cabin near the confluence of major river systems stands as the only marked structure, highlighting the remote character of the region during this era. Prominent landmarks like Porcupine Butte rise above the surrounding lowlands and numerous water bodies such as Red Lake and Red Salmon Lake. This survey provides a look at the natural drainage patterns and topographical features that defined this part of Alaska shortly after statehood, documenting the raw geography of the Hayes Glacier River system.
