1958 Map of Lake Clark D-1

About this map

The Neacola River headwaters and high-altitude glacial systems define this remote Alaskan interior landscape as it was documented in the late 1950s. Located in the Lake Clark region, the map reveals a wilderness of ice and moving water, with the Glacier Fork Tlikakila R cutting through the southeast. This survey was created using photogrammetric methods from 1957 aerial photography and field annotated in 1958, capturing the precise state of the ice fields before several decades of modern glacial recession. The topography is dominated by extensive Crevasses, marking the active flow of glaciers that feed into the regional river systems. This is a map of pure geography, showing a land without established roads or trails, where the only named features are the primary waterways and the dangerous fractures in the ice.
