1949 Map of Gulkana C-1

About this map

The Copper River dominates this mid-century Alaskan landscape, winding through a complex system of wetlands and tributary drainages just north of the Copper River Meridian. Surveyed in 1949 with minor revisions in 1966, the area showcases a wilderness era where the Glenn Highway served as the primary terrestrial artery, linking the remote interior across the valley. The map reveals an intricate network of water bodies, from the cluster at Cobb Lakes and Duck Lake to the glacial-fed silts of Indian Creek. This terrain, interpreted through aerial photography from the late 1940s, highlights the transition from upland mountain slopes down to the braided river flats. Geologists and surveyors of the era documented a landscape defined by significant hydrological features like Boulder Creek and Grizzly Lake, capturing the hydrography before modern development altered the remote drainages of the Drop Creek basin.
