1953 Map of Cordova A-7 and A-8

About this map

Hinchinbrook Entrance serves as the focal point of this coastal survey, marking the vital gateway between the open Gulf of Alaska and the sheltered waters of Prince William Sound. The map highlights the strategic navigational importance of Cape Hinchinbrook at the southwestern tip of Hinchinbrook Island, where a Lighthouse Reserve is established. Maritime history is further represented by a Lighthouse and a Radio Tower, critical infrastructure for vessels transiting these waters in the early 1950s. To the west, the edge of Montague Island appears across the strait, while the isolated Seal Rocks rise from the sea south of the main entrance. Depth soundings across the Pacific Ocean floor provide a detailed picture of the underwater topography and safe passages within the Chugach National Forest maritime boundary.
