1951 Map of Valdez B-6

About this map

The Chugach Mountains dominate this portion of the Alaskan interior, recorded in the early 1950s just as topographic photogrammetry was refining the mapping of the territory’s most inaccessible peaks. Massive ice fields define the hydrology here, with the Klutina Glacier, Tonsina Glacier, and Valdez Glacier carving through the high-elevation terrain. This survey provides a precise look at the glaciated landscape before modern retreat, noting numerous crevasses and naming peaks such as Mt Schrader, Mt Ourand, and Mt Evans. The northern reaches show the drainage patterns of Stephens Creek and the Klutina River, highlighting the transition from permanent ice to the river valleys that served as early transit corridors through the coastal ranges.
