About this map

Nakchamik Island dominates the central waters of this maritime survey, rising to a peak at Nak Island amidst the expansive Chignik Bay. To the north, the mainland reaches into the sea at Cape Kumliun, a prominent coastal feature that overlooks the western entrance to the bay. This 1963 field-annotated map provides a detailed view of the remote island chain stretching southeast toward the open Pacific Ocean, including Unavikshak Island and its solitary Cabin.

The presence of this Cabin on Unavikshak suggests a history of seasonal use or subsistence trapping in this seafaring region. Further south, the map charts smaller outcroppings such as Kak Island and Atkulik Island, while hazards like Katmai Reef underscore the navigational challenges of these Alaskan waters. The map's bathymetric data, compiled from earlier 1952 hydrographic charts, reveals the underwater topography that defined the local fishing and maritime economy of the early 1960s.
