1963 Map of Chignik A-1

About this map

Castle Cape dominates the northern reaches of this maritime survey, a jagged projection of land that separates the waters of Castle Bay from the open Pacific Ocean. This coastal landscape in the early 1960s is defined by its deep inlets and scattered island geography, including the isolated Chankliut Island situated several miles offshore. Small protected waters like Nikolai Cove and Necessity Cove provide a break from the exposed coastline, while interior landmarks like Pudding and Why serve as fixed points of reference for the mariner and surveyor alike. The mapping reflects a detailed coordination between the Geological Survey and the Coast and Geodetic Survey, utilizing hydrographic data to document the complex shoreline and seafloor depths surrounding the Northwest Arm.
