1958 Map of Lake Clark D-1

About this map

The Neacola River and the Glacier Fk Tlikakila R define the hydrological character of this high-altitude landscape in the Kenai Peninsula Borough. Surveyed in the late 1950s using photogrammetric methods from 1957 aerial photography, the topography reveals a dynamic environment dominated by ice and moving water. The map provides a specialized look at the glacial geography of the era, specifically calling out numerous Crevasses across the high ice fields. While the region lacks settlements or human infrastructure, the detailed contouring by the Geological Survey illustrates the steep drainage basins and the precise path of the rivers as they emerge from the surrounding glacial systems.
