1958 Map of Talkeetna C-5

About this map

Mount Dall dominates this glacial landscape within the Matanuska-Susitna Borough, serving as a high-altitude anchor for the massive ice fields captured in the late 1950s. The flow of the Surprise Glacier and Dall Glacier defines the area's movement, with numerous crevasses indicated across the ice surfaces, signaling the active nature of these frozen giants. These glaciers feed into a network of drainage systems, most notably the Tonzona River in the northwest and the West Fork Yentna River in the south. The presence of Cascade Creek further illustrates the complex watershed formed by the melting ice. This edition, featuring limited revisions through 1976, provides a specialized record of Alaskan glaciology before significant modern retreat, highlighting the sheer scale of the ice-carved terrain and the remote river sources that rely on it.
