About this map

Tugidak Island dominates this mid-century hydrographic and topographic study of the Trinity Islands in the Kodiak Island Borough. The landscape is characterized by its dynamic coastal features, including an extensive central Tidal Flat and the dangerous waters of Tugidak Passage. A lone Cabin on the southern shoreline and the Tugidak East Base station on the northern tip are the only markers of human presence, hinting at the remote nature of these islands in the early 1950s.

Navigational hazards and geographic landmarks are meticulously recorded, from the Exposed Wreck off the eastern coast to distinct survey points like Red Bluff 2 and Shallow Point 2. The survey, which also includes a portion of Sitkinak Island to the east, provides a detailed record of the shoreline before minor revisions were noted in the 1970s, serving as a vital resource for understanding the unchanging character of the Pacific Ocean coastline in this subarctic region.
