1959 Map of Nabesna A-5

About this map

Mt Gordon stands as a prominent landmark in this high-altitude Alaskan landscape, where the shifting ice of the Jacksina Glacier and the Nabesna Glacier dominates the terrain. The drainage patterns of the late 1950s are meticulously recorded, showing how Jacksina Creek and its tributaries, such as Mesa Creek and Monte Cristo Creek, carve through the glacial valleys. A single Pack Trail winding past Grizzly Lake in the northwest corner represents the only indicated human infrastructure, highlighting the extreme isolation of this region at the time of the survey. This map provides a specialized view of glaciological and topographic conditions in the Copper River Meridian before modern climate shifts significantly altered these frozen environments.
