About this map

Perry Island and Culross Island dominate this coastal survey of northwestern Prince William Sound, where deep glacial waters meet a complex shoreline of bays and passages. The maritime character of the early 1950s is evident in the presence of several cabins and a light station, signaling the area's importance for local navigation and seasonal use. While the islands are largely uninhabited by major settlements, the map documents the Lighthouse Reserve on the mainland and the strategic positioning of landmarks like Meares Pt and Billings Pt.

Waterways like Perry Passage and Lone Passage separate the landmasses, leading into sheltered inlets such as West Twin Bay and East Twin Bay. To the south, the terrain becomes increasingly complex around Falls Lake and the mouth of Port Nellie Juan. This survey, updated in the mid-1960s from earlier aerial photography, captures the intricate topography of Lone Island and Crafton Island before significant modern changes.
