1950 Map of Talkeetna Mountains A-5

About this map

The Talkeetna Mountains dominate this 1950s survey of the Matanuska-Susitna region, revealing a landscape defined by glacial activity and high alpine drainage systems. The Kashwitna River and its North Fork Kashwitna River carve deep valleys through the southern portion of the sheet, while the Sheep River provides a primary arterial corridor through the northeast. At this mid-century moment, the area remains largely untouched by permanent settlement, with land lines representing unsurveyed locations predetermined by the Bureau of Land Management. The intricate contour work illustrates the steep transitions from river basins to high peaks, particularly around Sheep Creek and the headwaters of S Fk Montana Creek. This map is an essential reference for understanding the hydrography and primary natural landmarks of the region before modern infrastructure began to alter the accessibility of the Alaskan interior.
