1951 Map of Talkeetna Mountains C-3

About this map

Talkeetna Mountains dominate this mid-century topographic survey, showing a high-altitude landscape defined by glacially-carved valleys and drainage networks. The northern portion of the map is anchored by Mt Watana and the nearby Watana Lake, while a series of parallel waterways including Kosina Creek and Tsisi Creek flow through the central terrain. Based on 1949 aerial photography, the map documents a primitive wilderness state with no roads or trails recorded at the time of the 1951 field annotation. The drainage patterns of Fog Creek and Terrace Creek illustrate the complex hydrology of this subarctic environment before modern infrastructure reached this part of the Matanuska-Susitna Borough. The absence of human-made landmarks emphasizes the topographical focus of the U.S. Geological Survey during this era of Alaskan mapping.
