1951 Map of Seldovia A-6

About this map

The waters of the Cook Inlet and the Gulf of Alaska meet at the southwestern tip of the Kenai Peninsula Borough in this maritime-focused survey. While the map is dominated by hydrographic soundings and deep-water contours, it captures the critical shoreline transition at the Chugach Islands, a significant landmark for Pacific coastal navigation. Photogrammetric data from 1951 details the rocky perimeter of Elizabeth Island and the prominent headland at Cape Elizabeth. This chart emphasizes the bathymetry and coastline of Koyuktolik Bay, documenting a remote maritime environment prior to modern nautical revisions, based on data compiled from early USC&GS charts to assist in understanding the treacherous coastal waters of the region.
