About this map

Hinchinbrook Entrance serves as the focal point of this coastal hydrographic study, where the waters of the Gulf of Alaska meet the Pacific Ocean. The map centers on the critical maritime corridor between the southwestern tip of Hinchinbrook Island and the eastern edge of Montague Island. This 1953 survey, derived from USC&GS hydrography and aerial photography, meticulously records soundings and depth curves, revealing the treacherous submarine topography surrounding Seal Rocks. On the island's prominent headland at Cape Hinchinbrook, the Hinchinbrook Lighthouse Reserve is clearly delineated, marking the site of a vital navigational aid. The inclusion of a Radio Tower and Lighthouse underscores the area's role as a sentinel for vessels entering Prince William Sound during the early 1950s.
