About this map

Afognak Island reveals a complex network of deep-water inlets and high coastal ridges in this 1950s study. The terrain is dominated by Edge Mountain, which overlooks the eastern coastline where King Cove and Tonki Bay indent the land. This entire land area is contained within the Chugach National Forest, emphasizing its status as protected wilderness during this era.

Coastal landmarks such as Pillar Cape and Peril Cape define the entrance to Izhut Bay, while several triangulation stations, including Vabm 1928 and VABM 525 Peril, indicate the precision of the mid-century mapping effort. The chart provides specific hydrographic data for Marmot Bay, capturing the shoreline as it existed before later seismic shifts in the region. Local names like Midarm and Saposa Bay offer specific reference points for researchers studying the island's maritime geography.
