1958 Map of Talkeetna C-4

About this map

Dall Glacier, Yentna Glacier, and the massive Lacuna Glacier dominate this interior Alaskan landscape, their ice fields carving deep valleys into the surrounding peaks. Mapped via aerial photography in the early 1950s, the terrain shows a raw, glaciated environment where the East Fork Yentna River emerges from the ice to wind through gravel bars and braided channels. To the southeast, the topography descends toward Chelatna Lake, fed by a network of drainage systems including Snowslide Creek and Easter Creek. The drainage patterns here are complex, with features like Sunflower Basin and Stern Gulch illustrating the sheer scale of the runoff from the high ice. While no roads or trails are noted on this survey, the naming of various tributaries like Idaho Creek, California Creek, and Colorado Creek suggests a history of prospecting or regional travel during earlier eras of exploration.
