1959 Map of Gulkana A-1

About this map

Mount Sanford dominates this landscape, rising as a massive peak amid a complex system of ice and river drainages. Compiled from mid-century aerial photography, the survey documents an era of active glacial activity where the Sanford Glacier and Dadina Glacier carve deep paths through the high terrain. The drainage patterns are clearly defined by the Sanford River and the Dadina River, which carry meltwater away from the frozen heights of the Wrangell Mountains. To the south, Mount Wrangell and Mt Zanetti stand as prominent landmarks, while Nathlie Mountain sits near the western edge of the ice fields. This map provides a technical look at the land's surface before later twentieth-century changes, specifically showing the vast reaches of the Chiehokna Glacier and Chetaslina Glacier as they were shaped in the late 1950s.
