1958 Map of Kenai D-8

About this map

Lake Clark Pass serves as the central focal point of this late 1950s survey, marking a significant natural corridor through the high mountain terrain. The hydrologic divide is clearly visible where the Tlikakila River flows to the southwest from the vicinity of Summit Lake, while drainage to the northeast is dominated by the North Fork Big River. The landscape is characterized by extensive glacial systems, including the Alto Glacier and several unnamed ice fields marked by numerous crevasses. Mapped primarily through photogrammetric methods from aerial photography, this document records a wilderness state prior to any established road or trail development, focusing instead on the raw topography of the Seward Meridian and the complex intersection of alpine peaks and ice-carved valleys.
