About this map

The Susitna River carves through this remote interior landscape at the start of the 1950s, serving as the dominant drainage for a network of glacial and mountain tributaries. This survey, based on 1949 aerial photography, documents the intricate confluence where the Tyone River and the Oshetna River meet the Susitna, a region defined by extensive marshlands and high-altitude survey points. The East Boundary Seward Meridian bisects the eastern portion of the sheet, marking a significant transition in the early land management of the Alaska Territory.

Evidence of human presence is sparse, limited to a single Cabin located along a small creek in the southwest. Surveyors established high-altitude benchmarks such as VABM Oshetna 4503 and Lone Butte 19 VABM 3668 to map this complex terrain. The map captures the natural drainage patterns of Tyone Creek and Sanona Creek before any significant modern infrastructure or roads reached this segment of the Talkeetna Mountains.
