1949 Map of Talkeetna Mountains A-4

About this map

The Talkeetna Mountains define this high-altitude landscape in the Matanuska-Susitna region, as documented through photogrammetric methods from aerial photography taken in 1949. This map focuses on the high-elevation glacial system and headwaters, where the Sheep River originates amidst a complex of massive ice fields. The eastern portion of the sheet is dominated by the Talkeetna Glacier and the Chickaloon Glacier, reflecting the ice-bound character of the region before late-20th-century climatic shifts. Sovereign Mountain stands as a primary landmark within this unsurveyed territory, where land lines remain largely predetermined by the Bureau of Land Management rather than established by field crews. The topographic data reveals a land defined entirely by ice and altitude, without recorded roads, trails, or permanent settlements at the time of the 1949 survey.
